Features of Rifar radiators

Rifar bimetallic batteries have a core made of special steelable to withstand significant loads, it has low heat transfer, while aluminum fins, on the contrary, have a high heat transfer.

Radiators have many advantages, thanks to which they gained great popularity:

• One of the main advantages is versatility of radiators, they can be installed both in multi-storey buildings with centralized heating, and with an autonomous mode. They are designed for 20 atm working pressure with a test pressure of 30 atm.
• Special inner coating protects from rust and other aggressive chemical compounds in water.
• Surface monolithic layer prevents scratches.
• The maximum temperature regime is 135˚С.
• High heat dissipation- with standardized heat supply from the boiler room, it is 200 W for each battery element.
• The small internal volume of one radiator element makes it possible to achieve low inertia.
• The price is lower than for identical batteries in terms of technical parameters imported radiators.
• Give in temperature regulation.
• Radiators can be painted in any color.
• Can be combined with a different number of sections.
• Work guarantee - 10 years.

Comparison of bimetallic and aluminum heating radiators

The power of the section of the aluminum radiator and the bimetallic one is identical. which gives them the same performance, but there are some differences in characteristics

which you should pay attention to when choosing batteries

• Reliability - for an autonomous heating system, in which there is no threat of a water hammer, aluminum equipment will be enough, but if it is supposed to be used in a centralized heating system, it is better to insure yourself and choose a bimetal as more resistant. It is guaranteed to withstand even a serious jump and not leak.
• Cost is one of the most important criteria that often outweighs any arguments. The cost of aluminum radiators is on average two times lower than the cost of bimetallic ones 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 buy 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 base series sections, but thanks to the bracket system, it is possible to produce 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 bending. It is noteworthy that all technical parameters are retained regardless of the form.

How to calculate the power of a 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 initially the calculation of the power and the number of sections was performed incorrectly. The calculation is based on the capacity of one section. It is indicated by the manufacturer in the product specification. But it must be borne in mind that the average indicators may 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 value rarely exceeds ∆t 50 ° C. At the same time, it is declared by the manufacturers as ∆t 70 ° C, which is ideal conditions.

When calculating, it is necessary to take into account other data:

• The location of the premises in the house.
• Condition of building structures.
• Dimensions and location of windows and doors.
• The materials from which the house is built.
• The type of boiler equipment used, etc.

The simplest calculation can be done using the formula - the area of ​​the room, multiplied by 100 and divided by the capacity of one section. For example, for efficient heating of a room with an area of ​​25 sq. m requires 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 a center distance of 500, 350 and 200 mm.

The RIFAR Base 500 model with a center distance of 500 mm is one of the most powerful bimetallic radiators, which makes it a priority when choosing radiators for heating large and low-temperature rooms. The RIFAR radiator section consists of a steel pipe cast under high pressure with an aluminum alloy with high strength and excellent casting properties. The resulting monolithic thin finned product provides efficient heat dissipation with maximum safety margin.

The availability of the RIFAR Base 350 and RIFAR Base 200 models with a center distance of 350 and 200 mm allows maintaining a uniform style in rooms with different height restrictions in the places of their installation. A feature of RIFAR Base 200 is the closed back surface of the section, which allows the device to be used in combination with French windows.

It is produced serially from 4 to 14 sections, color according to the RAL 9016 catalog.

As a heat carrier for Base 500/350/200 models, only specially prepared water is allowed, according to clause 4.8. SO 153 - 34.20.501 - 2003 "Rules for the technical operation of power plants and networks of the Russian Federation".

Confirming the high design characteristics of its radiators and strict quality control, it gives a guarantee for its products for a period of 10 years and at the same time guarantees its uninterrupted operation for 25 years from the moment of installation, subject to the rules of transportation, installation and operation. All products manufactured are certified in accordance with GOST 31311-2005 and insured by INGOSSTRAKH.

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 production can be primary, i.e. pure raw materials, or secondary, which is produced from scrap or dirty alloys. The price of the latter is much lower. When choosing any model, its performance characteristics are important, which include:

1. Working pressure is the amount of water exposure that a heater can withstand, while maintaining its original state. Modern devices have this figure from 6 to 16 atmospheres. Devices with low working pressure are used in private houses or apartments, summer cottages and cottages, where the coolant is controlled by the user. In communal heating systems, more reliable products are needed that will withstand pressure surges.
2. Heat transfer. 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.

Radiators of the Monolith series remarkably warm up even a large area of ​​the room, without the use of additional heating equipment.

Pros and cons

According to reviews of buyers 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;
• the possibility of installation in a private and centralized heating system;
• the maximum temperature of the heating 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 in comparison with foreign counterparts.

Rifar radiators not only differ in positive operational features, but also have some disadvantages:

• The equipment is not entirely 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 connection type. Each section has preset parameters for height, width and depth, on which the total heat output 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 in the center distance from 200 to 500 mm and different section heights allow installing Base series radiators with any type of window openings. The weight of one section does not exceed 2 kg, so assembly 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 a shallow depth, which is important when installing a heating battery under narrow window sills without a niche. The inner structure of each section is similar to the previous line, but the outer part of the case 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 makes installation easier and expands the possibilities for choosing the type of radiator mounting.

Both series of Rifar sectional radiators work with the same type of heat carrier, which is allowed to use technical water specified in accordance with GOST parameters. The manufacturer's warranty is 10 years, while compliance with the operating conditions increases the warranty period of the device's uninterrupted service to 25 years.

Rifar Base 500 12 sections

The technical and industrial revolutions pushed humanity towards inventions that have improved and made life easier. In just a little more than a century, people have switched from stove and fireplace heating to complex low-temperature heating systems that operate virtually autonomously. Such a breakthrough was made possible by the improvement of heating radiators.

Today, the best manufacturer of heating equipment in Russia is Rifar, whose products have been repeatedly noted at various exhibitions, and most importantly, have earned the well-deserved trust of consumers. Statistics show that the bimetallic radiator rifar base 500 12 sections is more often than other models installed in apartments, houses and various institutions with rooms of 24m2.

Selection Tips

When choosing heating batteries, technical features and operating conditions must be taken into account. The technical features possessed by heating batteries allow them to be installed in systems with forced operation of a heating agent. Rifar models have high heat output and long service life. Installed in high-rise buildings.

When choosing bimetallic radiators, you must focus on their positive qualities:

• Tightness thanks to a polyurethane bushing that 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 produced 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 recommended for educational, medical and administrative applications.

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 makes it possible to do without adapters during installation;
• tightness, which is ensured by laser welding of heating equipment.

However, monolithic bimetallic batteries cannot be connected to the autonomous heating system of cottages. The recommended optimum connection is to centralized heating systems.

An equally important point when choosing a bimetallic battery is the option to connect it. Rifar radiators come with side and bottom connections, 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 contour. 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 ensure intensive circulation of the coolant. The connection is made up-down. Thus, the heating agent will be supplied from the top, and the outlet will be through the lower channel.Also, with a large number of sections, a flow extension may be required.

Bottom connection radiators ensure stable operation of the heating system without installing additional elements. However, to squeeze 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 hydrogen index of 7 - 8.5. When using another thermal agent, there is no guarantee that the radiator will work.
• 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 installer.
• The radiator must reach room temperature before installation.
• Cannot be installed in rooms with high humidity levels (over 75%).

Only when these recommendations are followed can you not worry about the duration of the heating radiator's service life.

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 a window. For a corner room, it is better to divide this number in half or into 4 and 6 parts and mount it according to the device at each outer wall. Another option is to calculate the amount of heat required to heat the room:

1. For our example, it is - 100 * 16 = 1600 W or 1.6 kW.
2. Next, select a specific product and determine its heat transfer by multiplying the characteristic of one element of the same name by their number. For example, let's take a 6-section model with 180 W for one part - 6 * 180 = 1080 W.
3. Divide the required heat value by the power of the entire device - 1600/1080 = 1.48. We 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. With the injection molding method, each section is manufactured separately

The raw material is silumin - aluminum with silicon additives not exceeding 12%. By molding, sections of various shapes are obtained, capable of withstanding pressures up to 16 atmospheres.

The extrusion method is used to make not radiators, but their separate parts, then fastened together. This method makes it possible to reduce the cost of production, but in terms of technical characteristics, batteries created by the extrusion method 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 by far the highest quality. The raw material for their production is purified aluminum. The finished product is anodized, due to which it becomes absolutely non-corrosive. Individual parts in such radiators are connected by couplings.

Therefore, inside they are absolutely smooth, which means that they are not afraid of scale overgrowth. Their working pressure is up to 70 atmospheres.

Types of heating radiators Rifar

The range of Rifar products 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 wide range of Rifar products allows you to choose the model you like 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.

Radiators RIFAR 500: description, characteristics

The Russian buyer has already managed to appreciate the Rifar bimetallic radiators, and today this heating equipment is actively used and functions perfectly in many houses and apartments throughout Russia. The company took into account all the technical features of Russian heating systems and adapted its products to their requirements as much as possible.

Engineers of the Russian company RIFAR Base systematically monitor systems used in order to expand the range, increase the range of standard sizes and new accessories. Tests are carried out for the performance of radiators at a maximum possible pressure of 30 atmospheres, which is much higher than the working one. This guarantees the normal operation of this technique during operation, even with high surges in heating networks. The inner surface of the radiators is covered with a special protective layer, and the outer surface - with powder paint, which protect the radiator from internal and external corrosion and damage.
