Model description
Rifar 500 radiator design
The radiator section is a single steel tube, which is filled with aluminum alloy using a special technology under very high pressure. By means of a high-quality silicone gasket of the original design, the sections are connected to each other and a monolithic product is obtained, which has a high strength index and good heat dissipation.
Purpose
This model is the most powerful among bimetallic radiators and is designed for large rooms with poor insulation. The high heat output of the radiator guarantees heating and maintaining a comfortable temperature for production facilities or living rooms in a house or apartment.
Advantages
- Bimetallic radiators of the Rifar model line have low thermal inertia and are able to quickly change heat transfer parameters, that is, they quickly heat up and cool down. This allows them to be used in systems with autothermoregulation, which is their undoubted advantage.
- Rifar radiators can be used both in houses with centralized heating, and in houses or other objects with an autonomous heating system.
- They have a high margin of safety, as they are pressure tested under high pressure of 30 atmospheres, which ensures safety when used in emergency situations.
- Radiators have a long “life” resource and corrosion protection, thanks to a special coating of the inner and outer surfaces.
- Rifar models provide excellent heat dissipation and the highest possible temperature regime up to 135 degrees.
- They have a beautiful design and can be painted in any color at the request of the buyer.
- Radiators can be configured with a different number of sections.
- The core is manufactured using a special technology from special steel, as a result of which it is able to withstand very heavy loads and has a low heat transfer, while aluminum fins are high.
- With excellent quality and stylish design, they have an attractive price.

Comparison of bimetallic and aluminum heating radiators
The power of the aluminum radiator section and the bimetallic one is identical. which gives them the same performance, but there are some differences in characteristics
What to look for when choosing batteries
- Reliability - for an autonomous heating system, in which there is no threat of water hammer, aluminum equipment will be enough, but if it is intended to be used in a centralized heating system, it is better to play it safe and choose bimetal as more resistant. It is guaranteed to withstand even a serious jump and will not leak.
- Cost is one of the most important criteria, which often outweighs any arguments. The cost of aluminum radiators is on average two times lower than the cost of bimetallic radiators with equal characteristics. If we compare the price-quality ratio, aluminum wins, but subject to control of the pressure in the system.
Both bimetallic and aluminum radiators will meet their characteristics only if they are produced on modern equipment and according to technology. You should not try to save money and purchase a surprisingly cheap model from a little-known manufacturer. Probably its quality, regardless of the material, leaves much to be desired.

Flex
The uniqueness of bimetallic radiators of this series lies in the possibility of giving the plane a certain curvature. This model is equipped with sections of the base series, but thanks to the bracket system, it is possible to manufacture both convex and concave radiators.
The minimum bending radius is 1450 mm. To order radiators of this shape, you must specify the radius and direction of the bend. It is noteworthy that all technical parameters are preserved regardless of the form.
How to calculate the power of the radiator
Dependence on the number of pipes
No matter how high-quality the batteries are, they will not be able to provide the necessary heat transfer if the initial calculation of the power and number of sections was incorrect. The basis of calculations is the power of one section. It is indicated by the manufacturer in the specification for the product. But keep in mind that the averages can differ significantly from the real ones.
To calculate the heat transfer, the parameter ∆t is used, which is the difference between the air temperature in the heated room and the temperature in the system. In practice, this figure rarely exceeds ∆t 50°C. At the same time, it is declared by manufacturers as ∆t 70 °C, which represents ideal conditions.
When calculating, it is necessary to take into account other data:
- The location of the room in the house.
- Condition of building structures.
- Dimensions and location of windows and doors.
- The materials from which the house is built.
- Type of boiler equipment used, etc.
The simplest calculation can be done using the formula - the area of \u200b\u200bthe room multiplied by 100 and divided by the power of one section. For example, for efficient heating of a room of 25 sq. m need 16 sections. This figure is obtained from a simple calculation - 25 × 100/150.
Base
Its device is based on the special design of the parts of the connected sections and the parameters of the silicone gasket.
RIFAR Base radiators are presented in three models with center distances of 500, 350 and 200 mm.
The RIFAR Base 500 model with a center distance of 500 mm is one of the most powerful among bimetallic radiators, which makes it a priority when choosing radiators for heating large and poorly insulated rooms. Radiator section "RIFAR" consists of a steel pipe filled under high pressure with aluminum alloy, which has high strength and excellent casting properties. The resulting monolithic product with thin fins provides efficient heat dissipation with maximum margin of safety.
The presence of RIFAR Base 350 and RIFAR Base 200 models with center distances of 350 and 200 mm allows you to maintain a single style in rooms with different height restrictions at their installation sites.RIFAR Base 200 features a closed back surface of the section, which allows the device to be used in combination with French windows.
Serially produced from 4 to 14 sections, color according to RAL 9016.
As a heat carrier for Base 500/350/200 models, it is allowed to use only specially prepared water, in accordance with clause 4.8. SO 153 - 34.20.501 - 2003 "Rules for the technical operation of power plants and networks of the Russian Federation".

Power of one section of aluminum radiator
Such batteries are characterized by 2 types of construction: cast and extrusion. The first is made in the form of separate sections, and the second - in the form of glued or bolted 3 parts. In addition, the aluminum itself used for manufacturing may be primary, i.e. pure raw materials, or secondary, which is made from scrap or dirty alloys. The price of the latter is much lower. When choosing any model, its performance characteristics are important, which include:
- Working pressure - the amount of water exposure that the heater can withstand while maintaining its original state. Modern devices have this indicator from 6 to 16 atmospheres. Devices with low working pressure are used in private houses or apartments, cottages and cottages, where the coolant is controlled by the user. In municipal heating systems, more reliable products are needed that can withstand pressure surges.
- Heat dissipation. Heating devices made of aluminum have an advantage over cast iron ones, because they have high thermal conductivity, which leads to the release of the maximum amount of energy into the room. Heat transfer depends on the power of one section of the aluminum radiator and varies from 140 to 200 watts.
Popular series of bimetallic batteries Rifar
The most popular series of Rifar bimetallic batteries is Monolith. This heating system is innovative in technical terms, and heat transfer, tightness and reliability are at the highest level.
The Rifar Monolith series with a coolant having a temperature of 135 degrees and high pressure can work flawlessly for 25 years. In this case, various types of coolant are used, for example, antifreeze or ordinary water.
Radiators of the Monolith series remarkably warm up even a large area of the room, without the use of additional heat engineering.
Pros and cons
According to customer reviews using Rifar bimetallic heating batteries, the devices really have all the advantages, features and good quality.
Among the positive characteristics of radiators, it is necessary to highlight:
- versatility, since the battery can be installed both in an apartment building and in a private house;
- possibility of installation in a private and centralized heating system;
- the maximum temperature of the thermal agent is 135 degrees.
- high thermal power, due to which the room heats up in the shortest possible time;
- if necessary, it is possible to independently regulate the heating;
- low price compared to foreign counterparts.
Rifar radiators not only have positive operational features, but also have some disadvantages:
- The equipment is not completely made of bimetal. And fully bimetallic products have even greater heat transfer and high strength.
- Unreliable thread, but you can solve this problem yourself.
RifarBase and Alp radiators
The Base series is the simplest and most convenient for installation in apartment buildings with a standard type of connection. Each section has pre-set parameters for height, width and depth, on which the total heat transfer depends. The main advantage of the model is the ability to supplement the heating system with the required number of sections, taking into account climatic conditions, room size and layout features. Variations of interaxal distances from 200 to 500 mm and different heights of sections allow you to install radiators of the Base series with any type of window openings. The weight of one section does not exceed 2 kg, so installation and installation are quick and easy.
The Alp series is an improved model of the basic series of Rifar sectional radiators. A distinctive feature is the shallow depth, which is important when installing a radiator under narrow window sills without a niche. The internal structure of each section is similar to the previous line, but the outer part of the body differs in the arrangement of aluminum surfaces for maximum heat transfer at a shallow depth. The center distance is standard for the Alp line and is 500 mm. Due to the shallow depth, each section weighs less than 1.5 kg, which facilitates installation and expands the choice of the type of radiator mounting.
Both series of Rifar sectional radiators work with the same type of coolant, which can be used as technical water of parameters specified in accordance with GOST. The manufacturer's warranty is 10 years, while compliance with the operating conditions increases the warranty period of uninterrupted service of the device up to 25 years.

Selection Tips
When choosing heating batteries, it is necessary to take into account the technical features and operating conditions. The technical features that heating batteries have allow them to be installed in systems with forced operation of a heating agent. Rifar models have a high thermal output and a long service life. Installed in high-rise buildings.
When choosing bimetallic radiators, it is necessary to focus on their positive qualities:
- Tightness due to the polyurethane sleeve, which acts as a connecting element of the sections.
- High thermal performance - one section has a capacity of 0.104, 0.136, 0.204 kW. The maximum height of one section is 57 cm. Batteries are available in 4, 6, 8, 10 and 12 sections. The heated area of the room is 25 m2.
Monolithic bimetallic batteries are considered the most reliable heating systems that are recommended for installation in educational, medical and administrative institutions.
High heat transfer is created due to the optimal ratio of heat from the radiation and convection chambers.However, the heat transfer of such models is slightly less than that of conventional bimetallic batteries.
The main advantages of monolithic bimetallic radiators:
- the diameter of the pipe allows you to do without adapters during installation;
- tightness, which is ensured by laser welding of heating equipment.
However, monolithic bimetallic batteries cannot be connected to an autonomous heating system for cottages. The recommended optimal connection is to centralized heating systems.
An equally important point when choosing a bimetallic battery is the option of connecting it. Rifar radiators come with side and bottom connection, each of the options has some advantages.
Radiators with side connection - "Ventil". The connection is made by a special node, which is located at the bottom of the circuit. It often happens that after installation and connection, uneven heating of the sections occurs. To optimize heating, it is necessary to install a flow extension, which will provide intensive circulation of the coolant. Connection is made according to the top-down scheme. Thus, the heat agent will be supplied from above, and the outlet will be through the lower channel. Also, with a large number of sections, a flow extension may be needed.
Radiators with a bottom connection ensure stable operation of the heating system without installing additional elements. However, to compress air from the device, it is necessary to connect a Mayevsky valve and a thermostatic head.
In the passport of each device, the manufacturer indicates recommendations for the installation and operation of the product:
- Water as a heat carrier with a pH of 7 - 8.5. When using another heat agent, there is no guarantee that the radiator will work.
- In order to avoid premature corrosion, it is necessary to take care of grounding, grounding when using pipes made of metal or piping made of dielectric materials.
- The radiator must be installed by a specialized installation company.
- The radiator must reach room temperature before installation.
- Do not install in rooms with a high level of humidity (more than 75%).
Only when these recommendations are followed, you can not worry about the service life of the heating radiator.
In the next video you will find a video presentation of the production of Rifar heating radiators.
Calculation of heating batteries per room
It is possible to determine the number of products only after calculating the required number of sectional elements. Next, you need to decide how many devices you will be installing. In our example, it turned out that one should have 10 sectional parts. It can be a whole product installed under the window. For a corner room, it is better to divide this number in half or into 4 and 6 parts and mount one device at each outer wall. Another option is to calculate the amount of heat required to heat the space:
- For our example, it is - 100 * 16 \u003d 1600 W or 1.6 kW.
- Next, select a specific product and determine its heat transfer by multiplying the characteristic of one element with the same name by their number. For example, let's take a 6-section model with an indicator of 180 W for one of its parts - 6 * 180 \u003d 1080 W.
- Divide the required heat value by the power of the entire device - 1600/1080 = 1.48. Round this value up. As a result of the calculations, we get the number equal to 2.
Varieties of aluminum batteries
Note! Aluminum radiators are produced by two methods - casting and extrusion. When using the casting method, each section is made separately
The raw material is silumin - aluminum with silicon additives not exceeding 12%. By casting, sections of various shapes are obtained, capable of withstanding pressures up to 16 atmospheres.
Radiators are not made by extrusion, but their separate parts, which are then fastened together.This method makes it possible to reduce the cost of production, but in terms of technical characteristics, batteries created by extrusion are inferior to cast ones. They also have one more drawback - it is impossible to change the number of sections in the radiator.
It should be noted another type of aluminum batteries - anodized type. They are the most expensive and, of course, high quality. The raw material for their production is purified aluminium. The finished product is anodized, which makes it completely corrosion-resistant. Individual parts in such radiators are connected by couplings.
Therefore, inside they are absolutely smooth, which means that they are not afraid of scale fouling. Their working pressure is up to 70 atmospheres.
Types of heating radiators Rifar
Rifar's product range is quite diverse. The company produces monolithic and sectional radiators. There are products with a radius of curvature that are designed for rooms with convex or concave walls. Batteries are most often painted white, but any shade is selected at the request of the client.
Depending on what material Rifar radiators are made of, they are divided into the following types:
- aluminum. Rifar products are made of very high quality and durable aluminum, which is able to withstand pressure surges and large temperature changes. Such batteries have a very attractive appearance, and a large range of Rifar products allows you to choose your favorite model for any room.
- bimetallic. Such batteries are considered reliable due to the combination of several materials at once, while the level of heat transfer from the heating source to the air increases significantly.
