Overview of radiators Rifar Monolith

"Rifar Monolith": instructions for calculating the volume of the room

The previously considered calculation method is suitable for apartments with a classic height of 3 meters. For rooms with non-standard ceilings, the calculation formula for volume is used. According to the regulations, 39-41 watts of power is required for heating 1 m3. For the starting value, we take an area of ​​​​20 m2 with ceilings 3.3 meters high. We need to determine the number of radiator sections for heating equipment, taking into account the parameters of a particular model.

To calculate the total power of all radiator sections required for heating such a room, you need to find the product of area and height, and multiply it by 40 - the average performance indicator for heating 1 m3. The resulting number is divided by the power of one section of the radiator.

The following formula will turn out: X=Sxhx40:W.For the given example, the calculation looks like this: X=20×3.3×40:196, which is equal to 11.46. This means that for heating a room of 20 m2 with a ceiling height of 3.3 m, 12 sections of the Monolith 500 radiator will be needed.

The heat transfer of heating radiators is one of the main parameters that must be considered when choosing heating appliances.

This indicator directly determines the efficiency of space heating. When choosing radiators, it is imperative to take into account the heat transfer of the proposed devices.

The table above shows the heat transfer characteristics of one section for Ogint radiators, which, according to this parameter, are among the best on the modern domestic market. This data allows you to compare heat transfer for different types of radiators.

The heat transfer indicator, or power, of radiators characterizes how much heat the device gives off to the environment per unit time.

When choosing heaters, a calculation is carried out according to the heat transfer formula of radiators in order to determine the battery power. The resulting value is correlated with the heat loss of the room.

The optimal power is considered to be the one that covers the heat losses by 110-120%. This is the best heat transfer, at which a comfortable temperature is maintained in the premises.

Insufficient power will not allow the battery to heat the room efficiently. Increased heat transfer leads to overheating. For autonomous heating systems, too high battery power also means increased heating costs.

To increase heat transfer, you can add additional sections to the radiator or change the connection scheme.

For autonomous heating systems, an increase in the temperature of the coolant may also be available. When using any of these methods, the heat transfer of radiators must first be recalculated.

Thus, when choosing devices for a heating system, it is necessary to take into account their material and design features that are characteristic of a particular type of radiator.

Features of Rifar radiators

Bimetal radiators consist of a steel core and an outer aluminum layer.

Bimetallic radiators are in demand among apartment owners in multi-storey buildings connected to centralized heating systems. Due to some features of their design, they can withstand high pressure and withstand water hammer. They consist of a metal base, on top of which an aluminum "jacket" is applied by injection molding.

The resulting sections are combined into finished radiators, after which they are sent to stores. A strong steel core is responsible for their durability, while the aluminum “shirt” is responsible for good heat dissipation. Thanks to this combination of properties, bimetallic radiators have become so widespread. They can work in centralized heating systems, allowing you to heat apartments, offices, industrial workshops and many other premises.

Rifar heating batteries differ from classic bimetallic radiators. Many of us have read reviews that ordinary "bimetals" do not have a solid metal frame inside. And this is true - a solid steel base is present only in certain radiators, such as Rifar Monolith. But this does not prevent classic radiators from withstanding high pressure, reaching up to 25-30 atmospheres.

Despite high pressure resistance, conventional bimetal radiators cannot provide leakage protection due to the nipple connection of individual sections.

Monolith radiators are much more durable than their bimetallic counterparts, which is achieved by a welded seam between the sections.

Batteries Rifar Monolith are arranged differently. They have a steel base, the individual parts of which are welded together using special contact welding. On top of the base, by injection molding, an aluminum "shirt" is applied. What is good about such a “sandwich” with a whole core?

• No leaks - they simply have nowhere to come from;
• Robust design - no connections make the batteries extremely strong and reliable;
• High pressure resistance - they can work at pressures up to 100 atm.

The test pressure is 150 atmospheres. Such amazing resistance allows radiators to work even in the most difficult conditions - with constant pressure fluctuations and with strong water hammer. Given the presence of centralized boilers with outdated and unreliable equipment, Rifar Monolith batteries will become a reliable solution for high-quality heating without leaks and breakdowns.

Batteries Rifar Monolith are used not only in residential, but also in specialized premises, for example, in hospitals and kindergartens. They provide uniform heating and create air convection. It is also allowed to use monolithic batteries in industrial premises.

Using the Monolith battery

Increased strength of radiators allows them to be installed in high-rise buildings

The plant recommends using batteries of the specified series for heating any residential, industrial and utility buildings.

Increased strength allows installation in high-rise buildings.

For production, steel and aluminum grades are used, which allow the installation of the Monolith battery in preschool institutions and schools, hospitals and catering establishments.

The anti-corrosion coating does not deteriorate under conditions of short-term exposure to high humidity, so monolithic batteries can be used for heating basements and garages.

Advantages and disadvantages

Although the bimetallic radiator is distinguished by excellent qualities of consumer operation, it still has its drawbacks. The main disadvantage of Rifar heating equipment is associated with a partial bimetallic design. The disadvantages of radiators include weak threads.Cons are present in all battery models, so let's move on to the parameters that deserve acclaim. Rifar brand devices have a lot of advantages.

The main advantage is low prices for products. This characteristic is due to the fact that Rifar almost does not use expensive nodes in the device. The price is set depending on the number of sections, depending on the size and thermal insulation of the heated room. The production of the battery takes place according to the following method: incomplete use of bimetallic material using spot welding. This helped to reduce the cost of production quite well.

The company provides customers with a diverse range of radiators for different operating modes. These include: models that work only on a specific type of heat carrier (only filtered, soft water); radiators that work well with tap water of varying hardness; batteries that work with antifreeze and water.

1 Features and device

Rifar bimetallic radiators are produced by the Russian company of the same name and have been holding their positions in the heating equipment market for quite a long time. Rifar differs from its competitors not only in that it maintains all its production facilities in Russia (while most manufacturers have long since moved to China, with its cheap manual labor and resources), but also in a clearly defined course for innovation.

Actually bimetallic radiators Rifar Monolith are a complete confirmation of this.

The very word bimetallic means that we are dealing with batteries of a new type. They are made from several metal alloys that work in harmony and work for the benefit of the user.

It looks like a Rifar MONOLITH radiator

So, inside the heating radiator Rifar Monolith is made of steel. It is from steel that its supporting pipes are poured, which serve as vessels for transporting the heat carrier.

Steel in this regard is very convenient, because it is not affected by high temperatures, practically does not expand and is quite cheap. Coupled with amazing strength, it gives a really chic result. Batteries with a steel core are able to withstand much more serious loads, both in terms of operating pressure and in terms of carrier temperature.

Aluminum is simply not able to compete with steel in terms of the above parameters, but it has its own advantages. It is lighter, easier to process, looks better and, what is most appreciated by manufacturers, it conducts heat very well.

Aluminum batteries are easier to heat up. Metal quickly gains heat, but is in no hurry to give it away. In bimetallic batteries, the outer shell is made of aluminum.

So it turns out that the bimetallic radiator Rifar Monolit essentially has a combined device, which gives it advantages in several work areas at once.

Installation of a heating radiator Rifar Monolith

But we would be cunning if we stopped only on the pluses of steel and aluminum, as such. After all, any bimetallic radiator can boast of such solutions.

Rifar bimetallic heating radiators take their place in the market for a reason. And the point here is several improvements at once that touched all the points in the products described.

So, Rifar radiators are equipped with an improved section connection system. In fact, they are assembled directly at the factory by cold welding.This is a rather non-standard approach, but it definitely has its advantages.

For example, section connections are now completely secure. You should not worry about their depressurization or breakdown. The plant gives a guarantee for its products and this guarantee, it is worth noting, is quite long.

If you are going to buy Rifar bimetallic radiators, you can be sure that they will serve you without problems for at least several decades.

Also, right at the factory, threads are ground at the entrances to the radiators. Such a solution immediately throws aside all the inconveniences that concerned the connection of radiators. If earlier you had to deal with this as well, now it’s enough just to choose the right adapter.

And it is very easy to select it, because the thread is cut standard, any ball valve or coupling is suitable for work, in particular, taps of the “American” type, beloved by plumbers.

However, reviews of Rifar bimetallic heating radiators are not always one hundred percent positive. In rare situations, the presence of a standard thread only exacerbates the situation. For example, if you have some exotic heating devices and pipelines in your house.

Ways to connect Rifar Monolith

The second important point is improved steel as an internal frame. And it's not just about better stainless steel. Prices for bimetallic heating radiators Rifar are not in vain located at such a high level. The choice of material plays an important role here. And the steel used in Monolith batteries is first-class.

Compare for yourself, if a conventional radiator can withstand a pressure of 20-30 atmospheres, then Rifar Monolith 500 heating radiators can cope with loads of 100 atmospheres, and this is not the limit.

As for the temperature regimes, the bimetallic radiator RifarB500, for example, has an operating temperature range of 0 to +130 degrees Celsius. Which is more than enough (considering that heat networks rarely use carriers with temperatures above 100-110 degrees).

Who manufactures Rifar brand radiators

The Rifar company is a domestic manufacturer of heating systems. On the basis of the Rifar enterprise, a unique radiator design was developed that provides maximum heat transfer and low inertia. When producing and developing products, the manufacturer primarily focuses on domestic operating conditions. As a result, it was possible to develop a design that is resistant to the aggressive environment of the coolant, sudden pressure surges.

One of the achievements of the Rifar company is the production of radiators made with a radius of curvature, which makes it possible to carry out the most complex technical and design solutions.

The main policy of Rifar has been and remains the development of heating systems that are not inferior in quality to samples made by leading European manufacturers, but at the same time adapted to more severe domestic conditions.

Rifar Monolith and SUPReMO

Rifar bimetallic radiators of a new generation with a monolithic design have become a real breakthrough in the field of creating reliable home-made heating radiators.

The steel core was first created using the technology of contact-butt welding, which is patented by the company's engineers and has no analogues in the world. The one-piece steel body completely eliminates the possibility of leakage and is able to withstand hydraulic shocks in heating networks over 100 atmospheres.The thickness of the walls of the pipes for the passage of the coolant coincides with the thickness of the pipes in Russian systems, this thick layer is coated from the inside with an anti-corrosion compound and makes it possible to fill the system with any type of liquid.

The aluminum casing, which hides the internal structure, looks attractive, has no sharp corners, and thanks to the wide fins, it provides excellent heat dissipation and rapid heating of the room. Factory painting in several layers using a special heat-resistant material keeps well and does not require additional costs to maintain an attractive appearance.

To save money and maintain a comfortable temperature, monolithic structures are equipped with thermostats and control sensors.

Due to the monolithic structure, this type of Rifar radiator does not provide for additional sections or modifications, but is available with a large number of variations from 4 to 14 fins.

Depending on your preferences, you can choose one of the two series of a monolithic ruler.

• The MONOLIT series is similar to the bimetallic designs of sectional radiators, but this similarity is only external. A solid one-piece steel case is hidden inside, the tubes of the coolant circulation system are arranged vertically, and the small angle of inclination of the aluminum fins ensures high heat transfer parameters. The complete absence of sharp corners and heat-resistant coating facilitates the maintenance of the radiator, and the choice of the lower or upper connection type expands the operating conditions in various networks. Radiators manufactured after 2011 can work with antifreeze, as indicated in the instructions for the device. Rifar guarantees the preservation of the technical characteristics of the monolithic structure of this series for 25-50 years, depending on the model.

• The SUPReMO series is the embodiment of the dream of exquisite design, safety and excellent thermal qualities. SUPReMO's aluminum housing is a one-piece box, which makes the radiator look attractive and eliminate the possibility of accidental injury. Beveled side surfaces increase heat transfer and allow you to quickly warm up a large room. The inner surface of the steel body is coated with an additional protective layer, which increases the resistance to alkaline environments, makes it possible to use heat transfer oils and antifreeze liquids. SUPReMO radiators are adapted to the top and bottom connection type, suitable for left-hand and right-hand heating systems.

All designs are supplied complete with consumables adapted to a given diameter of heating pipes. Monolithic radiators are considered the best of all heating devices on the market today, and the reliability of Rifar has been proven by many years of successful experience and feedback from satisfied customers.
