Purmo radiators. Purmo radiators: technical characteristics of Finnish devices Basic technical characteristics and features

It is impossible to create an efficient heating system without high-quality radiators. It is on this element that fast and uniform heating of the room depends. Finnish Purmo radiators have all the technical characteristics necessary to create a comfortable microclimate in the house.

Purmo radiator range

Purmo products allow you to mount a heating system of any configuration. The company produces both tubular and panel radiators. In addition, the range includes heated towel rails, pipes, convectors and ventilation systems.

Purmo compact

This is a basic model of a panel radiator with a profiled surface, which has 4 side holes with a ½ ”thread for heating pipes. Products of this model are marked as follows - 11, 12, 22, 33. The first marking value indicates the number of panels along which the coolant moves, the second - the number of rows of internal U-shaped ribs to improve the convection effect. Accordingly, the larger the designation, the more powerful the device will be, but in this case its depth also increases.

Purmo Compact batteries are designed for use in one- and two-pipe heating systems closed type... Depending on the model, the length of the radiator can be from 40 cm to 3 m, and the height - from 30 cm to 90 cm. The permissible pressure is 10 atm. The maximum temperature of the coolant is + 110 ° С.

If it is necessary to supply pipes from below, a model with bottom connection Ventil Compact, in which the inlets can be located on the left or right side of the radiators. When ordering by phone, this point must be clarified. The Ventil Compact M has a bottom connection in the middle of the appliance.

All models with bottom connection are equipped with a thermostatic valve. Its customization is carried out in production. Additional adjustment required in rare cases, if for any reason his work is not satisfied.

Purmo Plan Compact

The technical characteristics of this radiator practically do not differ from the base model. The only difference is the smooth plate applied to the profiled panel and the high cost.

It should be noted that in all models with bottom piping, the coolant supply hole is on the left, and the coolant outlet is on the right.

Purmo ramo compact

In this model, as in the previous one, the profiled panel is covered with a plate, but it is not smooth, but made in the form of wide horizontal stripes. This solution emphasizes the strict design of the radiator and looks stylish in the interior of the room. The model has the possibility of side and bottom connection. Appliances with bottom piping are identified by the word Ventil. This model range includes the following types of radiators - 11, 21, 22, 33, 44. Devices are produced in lengths from 40 cm to 3 m, and heights from 20 cm to 50 cm. Allowable pressure up to 10 atm.

Purmo hygiene

Special hygienic type of radiators without internal fins. When convection flows move, dust particles rise along with them, which then settle on the inner surface of the radiator. The absence of ribs makes it easy to clean the appliance. The Hygiene model is recommended for installation in rooms where people with allergic diseases live, as well as in hospitals, kindergartens and others. public places Oh. In such radiators, the share of heat transferred by infrared radiation is much higher than convection heat transfer.

The Hygiene range includes 3 types of batteries - 10, 20, 30. All of them have versions with bottom side Ventil connection and center Ventil M, as well as Plan Hygiene with a smooth cover plate with all piping options.

Purmo Vertical

Vertical radiators are designed for rooms with limited horizontal space, but for heating which requires a large thermal power... The device has 4 holes for lateral piping and 2 at the bottom center for bottom connection. Vertical radiators are produced in the following types - 10, 20, 21, 22, width from 30 cm to 75 cm and height - from 1.5 m to 2.3 m. Allowable pressure up to 6 atm., Maximum temperature of the coolant - + 99 ° С ...

This type of radiator belongs to the design type and is more suitable for country houses or apartments with autonomous heating system.

Purmo air

Reinforced-plastic windows have good energy efficiency, but they must be periodically opened to ventilate the room, otherwise the lack of fresh air can cause you to feel unwell. The company's specialists took this problem into account and developed the Air model, which allows you to ventilate the room without opening a window.

The radiator is mounted on outer wall, next to it is done through hole and the filter is installed. After passing through it, cold air heats up from the radiator and dissipates around the room. Thus, a miniature heated ventilation system is obtained. Ventilation equipment is supplied complete with a radiator.

The line of Air models consists of devices of type - 11, 22, 33, length from 70 cm to 3 m and width from 30 cm to 75 cm. Allowable pressure - up to 6 atm., admissible temperature coolant - + 110 ° С.

Delta Laserline

This model belongs to the tubular type of radiators, consisting of sections. The design of each section is represented by two heads connected to each other steel pipes... Depending on the model, the number of pipe rows may vary. The sections are welded together into a single radiator. In this design, the quality of the welded seams plays an important role. For the manufacture of tubular radiators, laser welding is used, controlled by a computer system.

Delta Laserline models have the traditional shape used in these types of batteries, but in a slightly different design. The pipes are made not round, but in the shape of the letter D, due to which more efficient heat transfer is achieved at a smaller size.

The length of such batteries varies from 20 cm to 2.5 m, the height is from 15 cm to 3 m. It is possible to manufacture radiators of any height according to individual sizes... The permissible temperature of the coolant is 120 ° C, at a pressure of up to 10 atm.

Also available is the Delta Twin M model, which has a similar design, only in vertical design. It does not provide for the possibility of lateral connection - the pipes are supplied from the bottom in the center. The lineup consists of two batteries 50 cm and 60 cm long, height - from 1 m to 2 m.

Purmo Delta Bar

This radiator is truly exclusive. It can serve not only as heater, but also as a decorative table or even a bar counter. It can also be used as a partition for room zoning.

The inlet pipes are hidden in the lower legs and along the outward appearance the device looks more like a designer table, and not like a heating radiator. The cover is not included in the package of delivery, it will have to be ordered separately. The length of such a product without a table top is from 70 cm to 1.1 m, the height is from 75 cm to 90 cm. The permissible pressure is up to 10 atm., The maximum temperature is + 120 ° C.

Purmo Delta Column Bench

Another exclusive development of the designers of the Purmo company. At the same time it can function as a heater and a decorative bench. As in the previous model, the inlet pipes are hidden in the legs, the only difference is in the horizontal arrangement of the pipes. The base model is colored in White color, but on individual order painting in any shade from the color palette is possible. The length of such a "bench" is 1.5 m to 1.8 m, height - 20 cm to 35 cm. The maximum pressure is up to 10 atm., The permissible temperature of the coolant is + 120 ° C.

It is worth noting that Purmo gives a 10-year warranty for all the described models of radiators.

Advantages and disadvantages of Purmo radiators

For the manufacture of Purmo radiators, high-strength steel with a thickness of 1.25 mm is used. Products are painted using the technology used in the automotive industry. Radiators are immersed in a container with a primer solution, and then a special paint is applied under the influence of an electrostatic field. This technology allows the coating to firmly adhere to the steel surface, which completely eliminates the possibility of peeling and swelling of the paint during temperature fluctuations. Products are painted white, but there is a possibility of painting by individual order. To select a color, the customer is provided with a palette of 700 shades.

Purmo products have a wide range of benefits:

• efficient heat transfer due to natural convection and infrared heat radiation;
• the simplicity of the design ensures a long service life, since there is simply nothing to break in the device;
• various options for supplying heating pipes allow the installation of radiators in any conditions;
• Purmo radiators are lightweight and do not require massive brackets during installation;
• due to the small internal volume of the devices, a high efficiency of the heating system as a whole is achieved;
• the cost of metal radiators is much cheaper than similar aluminum products;
• the aesthetic appearance of the radiators harmoniously fits into the interior of any room;
• Purmo radiators have universal design allowing them to be used in one- and two-pipe heating systems;
• quality paintwork reliably protects the outer surface of radiators from corrosion;
• it is possible to choose a color in accordance with the design of the room.

Disadvantages of Purmo radiators:

• in district heating systems service providers for summer period the coolant is drained; if air enters the device, the metal may corrode.
• due to the presence of a large number of welded seams, radiators do not withstand water shocks well, which imposes restrictions on their use in heating systems operating under high pressure.

Purmo monitors the quality of products at all stages of production and is constantly looking for ways to improve products. All Purmo products are standardized and certified.

Purmo, which produces steel radiators, belongs to the European concern Rettig Heating. The company pays great attention to the quality of the manufactured products; all the required European and Russian certificates have been obtained. The range of campaigns includes both panel and tubular radiators, there are also convectors, heated towel rails, ventilation systems and pipes. In general, if desired, the entire heating system can be made from the products of this company.

Panel radiators

For heating devices of any type, high-quality coloring is very important: it not only improves the aesthetic appearance, but also protects the metal from oxidation. Therefore, painting is one of the key points of production. Purmo radiators are painted according to the technology used in the automotive industry: first, they are immersed in a bath with a primer solution, and then a special type of paint is applied in an electrostatic field. As a result, the paintwork adheres perfectly to the metal surface, does not flake off and does not swell even at temperature extremes.

In the basic version, all products are painted white, but if necessary, you can order any color from the standard palette, which is more than 700 shades.

Basic model Purmo Compact

It is a panel steel radiator with a grooved front panel. Side connection - four outputs with internal thread½ ”. The following types are produced: 11, 12 (or 21 are the same), 22, 33. The first number indicates the number of panels on which the heat carrier runs, the second - the number of additional convection panels. The more panels, the more powerful the radiator will be, but its depth will also be greater. They can be used both in one-pipe and two-pipe systems of a closed type.

The technical parameters are as follows:

• Sheet thickness on the panel is 1.25 mm.
• The step between the vertical channels for the coolant is 33 mm.
• Height from 300 mm to 900 mm (in 100 mm increments).
• Length from 400 mm to 3000 mm (up to 1200 step 100 mm, then variable).
• The power varies in a very wide range: from 289 W (type 11, size 300 * 400 mm) to 13058 W (type 33, size 900 * 3000 mm).
• The price also depends on the type and size: from 44 to 598 euros.
• Ph from 8 to 9.5.
• Operating pressure- up to 10 Bar, test up to 13 Bar;
• Heat carrier temperature up to +110 o C.
• The warranty period is 10 years.

The same model can be produced with bottom connection. Then it is called Purmo Ventil Compact. In this modification, the nozzles for heat transfer fluids can be located at the bottom right or left (specify the type you need when ordering). There is one more modification with the bottom connection Purmo Ventil Compact M. It differs from the previous model in that the entrance at the bottom is in the middle. This option is convenient in that you can simply remove the pipes and not mount the radiator yet, which is undesirable and problematic when connected to the side.

All models with a bottom feed are factory fitted with a thermostatic valve. The valve is pre-configured, therefore it can be left unadjusted (tuning is needed if its operating mode does not suit you).

Panel radiators "Purmo" with bottom connection are designed for installation in two-pipe systems (for one-pipe systems the hydraulic resistance of the valve will be too high). The technical characteristics completely coincide with the base model, there is a difference in price - they are more expensive by about 20 euros (the cost of the valve).

Smooth panel battery Purmo Planora (PCV) or Plan Compact

This is a variant of a steel radiator with a smooth front panel.

Connection types, dimensions and heat output and others specifications coincide with the parameters of the base model:

When installing any Purmo radiator with bottom connection, remember that the supply pipe is on the left and the return pipe is on the right.

Front panel with horizontal stripes Purmo Ramo Compact

Wide horizontal stripes are stamped on the front panel. This modification is available with side and bottom connections. For the bottom connection, the word Ventil is added. Five types are produced: 11, 21, 22, 33, 44. Technical characteristics of "Purmo Ramo Compact":

Special type Purmo Hygiene

Any of the above options can be produced without additional fins. This is the Purmo Hygiene class. Such radiators are necessary in hospitals and clinics, as well as for those who have allergic diseases.

Perforated metal plates significantly increase heat transfer, but small distances between them make cleaning difficult and troublesome: no brushes or even a steam generator can clean them, which is unacceptable for medical institutions. Also, without additional panels, the proportion of radiant heat increases, the percentage of convective heat transfer decreases, which is important for public places. Available in three types: 10, 20, 30.

The "Hygiene" model does not contain additional ribs, therefore they are easy to wash

There are variants Purmo Hygiene - this is a modification of the Compact model with side connection, Ventil Hygiene - also but with a right or left bottom connection, Ventil Hygiene M - the bottom connection is located in the center of the heater. There are similar models in the Purmo Plan Hygiene modification. There is also a "Gate" and "Gate M" model.

Vertical panel radiator Purmo Vertical

This unusual model fits well in those premises where there are few free horizontal surfaces, and the heat power is required large. There are four pipes for the side connection and two, located in the center, for the bottom one. The options for supplying the coolant are shown in the figure.

Types of vertical panel radiator - 10, 20, 21, 22.

According to the technical characteristics, it can be said unequivocally - this is a model for private houses, or for multi-storey houses with an independent heating system, the parameters of which are not higher than those indicated for the radiator.

Radiator with ventilation Purmo Air

Modern metal-plastic windows save heat well, but completely block the access of fresh air to the room. Lack of oxygen can lead to poor health and the development of diseases. The Purmo Air radiator is installed on an external wall, a hole is made in it, from where air comes from the street. It goes directly to the built-in filter, and then passes through the radiator and heats up. It turns out that this type of heating device is a miniature heated ventilation system.

Structurally, the Purmo Air system consists of a typical panel radiator 11, 22, 33 and a small set of ventilation and filtering equipment, which is installed behind it.

Various models and types, capacities and dimensions, the ability to paint the radiator in any color - all this makes it possible to choose a Pumo panel radiator for any room. But once again we draw your attention to the fact that they are suitable only for closed-type systems (with a low oxygen content and a small amount of suspended particles in the coolant). That is, they will show themselves best in individual heating systems.

Tubular radiators

Steel tubular radiators are very decorative even in the most simple execution, but subject to them quality workmanship... And Purmo radiators are renowned for their quality. Structurally, this type of heating devices consists of two section heads (upper and lower), which are stamped from a steel sheet. Steel pipes are then welded to them. Rows of pipes (or columns) can be from two to six, and the depth of the section changes accordingly. The finished sections are welded together into a single radiator, after which it is tested for tightness, then they undergo anti-corrosion treatment and painted (in any color from the RAL palette).

The appearance and reliability of tubular steel radiators largely depends on the quality of the welded seams. At the enterprises of "Purmo" laser welding is used, the process is controlled by computers, therefore connecting seams are reliable and visually indistinguishable. The impression is that this is a single design.

Delta Laserline and Delta Laserline VT

The classic shape for this type of radiator, but in a special design: the pipes are not round, but resemble the letter D in cross-section. This gives an increase in the heating area, and therefore more power with smaller dimensions.

A very wide range of models allows you to choose a heating device for any conditions and any preferences. The general specifications are as follows:

The Delta Laserline VT modification is a tubular radiator with bottom connection. The pipes for supplying the coolant can be located on the right or left, as well as in the center (only in versions with an even number of sections). A thermostatic valve is installed on any of the batteries.

High radiators Delta Twin M

This tubular radiator - perfect choice in places where there is not enough free horizontal space for the battery of the required power. Only a two-pipe version is produced, the connection is lower central. Mounting brackets (four) are welded to the rear panel, brackets are included.

Technical characteristics of "Purmo Delta Twin" indicate that they can work even in systems central heating, but always with an independent connection (check in the management campaign):

• Length 500 mm and 600 mm (10 and 12 sections).
• Height 1000 mm, 1200 mm, 1500 mm, 1800 mm, 2000 mm.
• Depth - 63 mm.
• Heat output from 753 W (size 500 * 1000 mm) to 1762 W (size 600 * 2000 mm).
• Ph from 8 to 9.5.
• The warranty period is 10 years.

Practical Purmo Delta Bar

This battery can be designed as a table or bench, it can be used as a dividing partition between zones in the room.

Connection is only possible in the following way: supply from the bottom left in the extreme section (in the left leg), the return pipeline on the bottom right (in the right leg). Supplied without top cover. Standard color- white varnish, on order - any color from the RAL palette. The piping is hidden, so few people will guess that this is not a designer table, but a heating battery. Specifications are as follows:

• Length 720 mm (700 mm without table top), 920 mm (900 mm), 1120 mm (110 mm).

• The warranty period is 10 years.

When installing under a window sill, the following distances must be observed: at least 10-12 cm from the floor and window sill. If the distance is from 7-10 cm, the power must be increased by 5-10%. An even shorter distance will make heating completely ineffective. In this case, it is necessary to select a radiator with a lower height.

The piping must be done in such a way that after the completion of the work there is no stress left, either in the pipes or in the fittings. During installation, the radiators must not be heated (for example, with a blowtorch).

If we talk about heating systems, then it is advisable to take advantage of the developments of those who have an understanding of harsh winters. For example, Finland, in terms of its climate, cannot be called a resort. In addition, Finnish products are renowned for their quality. Heating radiators "Purmo" are no exception. Today these devices are used in many countries, and Russia has also appreciated their advantages.

Application area

Purmo is a popular Finnish company engaged in the production of high quality steel heating devices that comply with European and international standards, including ISO 9001. Purmo are radiators that are used for heating both in houses and in non-residential premises in one-pipe or two-pipe pump heating systems.

Having bought Purmo steel radiators, you will not regret your choice for the following reasons:

• Data heating devices have a wide range of applications.
• "Purmo" - radiators that combine at the same time high efficiency and modern design.
• The technical characteristics of these devices meet high requirements - low thermal inertia and high heat transfer.

Advantages

In the manufacture of these heating devices, homogeneous high-strength steel is used. The device is painted using the same technology as at the enterprises of the popular automobile giant Mercedes.

TO undeniable advantages radiators of this model include the following:

disadvantages

When choosing heating devices of this brand, the fundamental point is that they can be used in closed central systems and places where there is no corrosion on metal surfaces. If the radiator is installed in a room with a high humidity regime, then additional anti-corrosion treatment should be provided.

• Color - pure white RAL 9016, other colors are available on request.

Connection options

Connection of "Purmo" radiators can be carried out different ways... The most popular is the side attachment, which is possible on both the right and left sides.

Besides, in recent times the most demanded are “Purmo” radiators with bottom connection. For heaters, the length of which is more than 2 m, it is recommended to cross-connect the nozzles, due to which it is ensured even distribution heat along the entire length of the panel. In a specific case, when it is not possible to connect a radiator in the above ways, an intermediate or saddle connection is used.

Varieties

The range of these heating devices is represented by five main types. Compared to aluminum devices "Purmo" (radiators) differ in connection types and workmanship:

1. Purmo Compact C - radiators with side connection.
2. Purmo Ventil Compact VKO - devices with a thermostatic built-in valve, with a bottom or side connection.
3. Purmo Hygiene P are side-connected appliances that do not have convection elements.
4. Purmo Ventil Hygiene PV are radiators with thermostatic built-in valve, with bottom or side connection. Convection elements are not provided.
5. Purmo Planora Plan DF are devices that have both bottom and side connections.

Radiators must be installed in accordance with current regulations. Protective film it is advisable to remove it from the device after completion of construction and installation work.

The type of bracket is selected depending on the structure of the walls, taking into account the mass of the radiator and operating conditions. The heaters can be installed on stands fixed to the floor. Radiators can be installed in heating systems with plastic, metal-plastic, steel and copper pipes.

If the heating system is hidden in the wall structure, it is advisable to install devices with side connection (type C), but if it is in the floor, it is preferable to choose radiators with bottom connection (type V).

When installing heating devices under window openings, the height of the radiators should be calculated taking into account the distance from the window sill to the floor, while the lower edge of the device should be at least 100 mm from the floor surface, and the upper edge - 100 mm from the window sill.

High quality painting

The main purpose of steel radiators of this brand is not only to heat the premises, but also to achieve a single harmony with the interior. Manufacturers for painting use technologies that are used in the automotive industry and are characterized by durability and increased durability of the effect.

Palette basic colors allows you to choose such products of the "Purmo" brand (radiators), which will ideally fit into any interior, and if necessary, you can order an individual color of the device.

Functionality and design

Steel panel radiators "Purmo" are functional self-sufficient elements of interior design, as well as integral components effective system heating. European quality, which was recognized by Austria and Germany, is an indicator of the professionalism of the manufacturer. The company's designers and engineers have created excellent Purmo radiators. The technical characteristics of these heating devices are unique - high heat transfer coefficient, versatility in application, own style.

Getting into a room, very often we do not even look at the heating devices installed in it - the selected models are so plain and impersonal. The same cannot be said about the devices instantly attract attention with their harmonious colors and unique design. Perfectly fitting into absolutely any interior, panel heating devices become one of the main elements of the room, focusing on comfort, modernity and style.

Diversity lineup often plays the very role that becomes the reason for the purchase. That is, when we come to a store and come across a brand of heating radiator, in which there are several models, we begin to tend to buy one of them. And if in the model range there are types of batteries that are designed for different types premises, then this is a big and fat point and one hundred percent guarantee that one or more devices will be purchased without fail. This is how the Purmo radiators, produced by the Finnish company, have more than three dozen types (models) in the model range.

Steel radiators

Let's start with the fact that the Finnish company, by the way, has its own branch in Poland, so this should not confuse you, it manufactures only steel radiators "Purmo". Here is a panel view and a tubular one.

Bathroom tubular radiators

I would like to note the heating batteries, which are produced specifically for bathrooms with heated towel rails. This group of devices stands apart because it has a number of technical and functional differences:

• Firstly, the classic version of bathroom radiators is vertical batteries. There are three groups: traditional with tubular sections, with offset sections relative to the center of the radiator, with sections in the form of window blinds. The last look is a novelty of the season.
• Secondly, horizontal devices with curved tubular sections. The manufacturer specially produces this type. It is used for design decisions.
• Thirdly, a radiator with one vertical collector. Tubular sections are horizontally installed to the side from it, on which you can hang towels for drying. different widths... That is, the width is not limited to the second manifold. This version of the radiator is non-standard, but very convenient to use.

We must pay tribute that tubular models are used not only in bathrooms. The company today offers a fairly wide variety. For example, Delta Bar. It is a tubular radiator with horizontal collectors and vertical pipes, on top of which a table top is installed. In fact, it is a bar counter that can be used by direct appointment... But at the same time it is also a heating element. With its help, you can divide the space of the room by organizing two separately operated zones. Convenient, beautiful and functional.

We add that the Purmo tubular radiators for ordinary rooms are four full-fledged models, differing from each other in design features.

Tubular vertical version

Panel batteries

For many reasons, steel panel radiators "Purmo" are very popular in Russia, which have an unusual line for Russians such as the height of the device: 300, 450, 500, 550, 600 and 900 mm. This creates some inconvenience, but practice has shown that designers can easily cope with this problem. Moreover, Purmo radiators have good technical characteristics, plus an acceptable price, that is, the ratio of these two most important indicators is optimal. This is what most often leads to demand.

Let's focus on one model and consider the technical characteristics of the "Purmo" radiator. For this we will take the most popular type - this is the "Compact" model. This device is specially produced for city apartments, it has a side connection, which is the most demanded.

Currently, the manufacturer offers three types of heaters: 11, 22, 33. In relation to the height, each type has its own characteristics that relate to the volume of sections, their heat transfer and installation dimensions. Below is a table where all indicators are collected in one place.

The heat dissipation of the device will depend not only on the height, but also on the length of the radiator. Note that the ruler of this size varies from 40 to 300 cm. It turns out that before choosing a heating battery and calculating its power, it is necessary to determine the size of the installation site. That is, the landing dimensions are determined and the dimensions of the radiator itself are already selected for them, taking into account its power. The selection is not difficult, for this you will have to use the ratios of all sizes.

There are several examples of this relationship:

• Type 11, height 30 cm, radiator length 40 cm - thermal conductivity will be 218.
• Type 11, height 900 cm, length 40 cm - thermal conductivity 1304.
• Type 22, height 50 cm, length 100 cm - thermal conductivity 1407.
• Type 22, height 90 cm, length 300 cm - 7164.
• Type 33, height 30 cm, length 100 cm - 1347.
• Type 33, height 60 cm, length 100 cm - 2356.

As you can see, the power of the heating radiator varies depending on the size of the device itself.

Heater device

Рurmo Сompact radiators withstand the coolant pressure up to 10 atm., While the water temperature should not exceed + 110C. For an autonomous heating system, this is the ideal model. In urban conditions, failures occur in the form of hydraulic shocks, but Purmo radiators cope with them without problems, because high-quality materials are used in their production process and Newest technologies welding.

Attention! The traditional color of the Purmo radiators is snow white (RAL 9016). The manufacturer and designers believe that this is the most democratic color that can be entered into any room interior. But on request, batteries can be painted in any shade according to the RAL catalog.

On the Russian market, there is another representative of the Purmo model range, which is very popular - this is the Purmo radiator with a bottom connection of the Ventil Compact model. I would like to draw your attention to the complete set of this type:

• Mounting brackets.
• Plugs.
• Mayevsky crane.
• Thermo valve.

The last device is installed at the factory only in this model, for the rest it will have to be purchased separately. But Ventil Compact does not come with locking and connecting assemblies, you have to buy them. By the way, the connection node can be angular or straight, it all depends on where the pipes of the heating system of the house are laid.

Conclusion

It is not for nothing that Purmo heating radiators are so popular today. It is actually a high quality heating device with excellent heat dissipation. True, the guaranteed service life given by the manufacturer is only 10 years. But if you use the radiator correctly and achieve good technical characteristics of the coolant, then the period can be almost doubled.

PURMO Compact С 22

Panel steel radiators PURMO PURMO Compact С 22 equipped with convection elements, lateral surfaces reliably closed with protective elements, the upper part of the radiators is closed with a "grill" bar. The steel radiator has four side connection holes in each corner of the radiator with a G1 / 2 "female thread. This arrangement of the holes allows the panel radiator to be connected with three possible ways- lateral connection, diagonal and saddle. Thus, we can choose the most suitable option connections.

Side connection

This is the most popular solution, allowing radiators to be connected both on the right and left. The supply pipe must be connected to the upper radiator connection, and the return pipe to the lower one. The opposite connection will reduce the heat dissipation of the radiator by more than 30%.

Crossover connection.

Recommended for radiators over 2,000 mm in length, as well as for those whose length is four times the height. The supply pipe should be connected to the right or left upper nipple and the return pipe to the opposite lower nipple. The opposite connection will reduce the heat dissipation of the radiator by more than 30%.

Saddle connection.

Most often it is used in type C radiators, when the central heating system is located in the floor. In addition, it can be used in "H" type radiators, and after removing the thermostatic valve - also in CV and HV type radiators. With this type of connection, the heat dissipation of the radiator will be approximately 10% lower than the nominal.

Hydraulic characteristics Purmo Compact C 22

The resistance to the flow of water through the radiator depends on the flow of its mass.

For single-panel radiators of type C11 and H10, the pressure drop in the radiator is described by the formula:

Δp = 0.0160 * q2
Kv = 2.5 m3 / h

For multi-panel radiators of type C21s, C22 and C33, as well as H20 and H30, the pressure drop in the radiator is described by the formula:

Δp = 0.0105 * q2
Kv = 3.1 m3 / h
where:
Δp - resistance to water flow through the radiator, expressed in pascals
q is the flow of a mass of water passing through the radiator, expressed in kilograms per hour

Radiators of type V and PV are equipped with a built-in thermostatic valve, and therefore their hydraulic characteristics are determined for a radiator kit with a valve.
