Radiators "Radena" are heavy-duty equipment for heating. Today these units are among the most popular on the market. And this cannot be called an accident or luck. After all, the batteries of this manufacturer have earned popularity for their high quality, as well as long service life. These products consist of separate sections, which have paronite gaskets and steel nipples for connection. The interior is a tube frame based on carbon steel. By purchasing this equipment, you can count on a long service life, which is ensured by the exclusion of contact of the aluminum shell with water. The manufacturer has created conditions that exclude electrochemical corrosion.
Technical characteristics of sectional bimetallic radiators of different models
Bimetallic radiators "Radena", presented on sale as sectional products, are designated as CS 150, CS 350, as well as CS 500 / VC 500. All of them are capable of operating at a pressure of 25 atmospheres, the test pressure for all three models is 40 atmospheres, while burst pressure is equivalent to 90 atmospheres. The temperature of the coolant also does not differ and is 110 ° C, the same cannot be said about the heat output of one section. In the first case, the parameter is 120, in the second - 135, while in the third - 185 watts.
Aluminum heating equipment
Although many experts offer buyers to purchase Raden bimetallic heating radiators, this is not a mandatory rule. Aluminum as a material of manufacture is quite good in terms of heat transfer and a number of other important characteristics. If the working environment permits, the application pays off. Some rules still need to be taken into account.
Radena aluminum radiators are used in systems based on water heating. Buildings - administrative, residential, public. Low-rise buildings are suitable.
Let's give a little advice. Before buying a radiator, be sure to find out if it is suitable for the main pipelines of the facility where installation is required. Failure to follow the rules of use after installation is unlikely to lead to terrible accidents, as they like to scare unlucky buyers. But the heating equipment will fail. And, with a high probability, finally.
Manufacturing process and cost
It's time to talk about more serious things. Let's start with a little help, which is that Raden's aluminum heating radiators are made from a number of sections. The latter are cast under high pressure. Then they are connected into a single whole. For this, steel nipples and special gaskets are used.
Radiator aluminum Radena 500.
Products are painted with epoxy polyester. A couple of layers are applied. If you are well versed in various technical subtleties, we add that two methods are used to create a protective coating. The first is cataphoresis. The second is electrostatic spraying. It is a powder enamel. At the very end, the product is covered with a paint compound that belongs to class A.
You need to know the following - both the manufacture and painting of Radena aluminum radiators are done at an acceptable level. There are two types of aluminum products to choose from - R350 and R500. The price of the R350 is from about $ 11.3 per section, R500 - $ 11.8.
Specifications
The basic properties of the R350 and R500 are not very different. We will consider the first option. If the R500 differs in something, we will explain it separately.Normal operation of the radiators is guaranteed at an operating pressure of the heat carrier of 16 atm. As for the test one, it is 24 atm. The burst pressure is 50 atm.
The heat output of one section is very high - 165 W. The R500 has a little more - 192 watts. In order for the heating equipment to serve for a long time, the temperature of the coolant should not exceed 110 degrees. Plus, more than 0.02 mg of oxygen is prohibited per liter of working fluid. Pay attention to pH. The valid value is 6.5 to 9.
One section of the product holds 0.275 liters (R500–0.330 liters). The weight also varies to some extent. R350 - 1.05 kg, R500 - 1.35 kg. Section heights are 431 mm and 581 mm respectively for different models. The center distance is 350 mm and 500 mm (hence the indexes in the name). The remaining indicators are the same again. For example, the depth of the radiator section is 85 mm. Width - 80 mm. The inlets for connection have a diameter of 1 inch. White color.
We believe that the information provided is more than enough to superficially evaluate aluminum products. Let's move on to a more interesting option. We are talking about bimetallic heating radiators Radena, which are even more versatile.
Dimensions (edit)
When choosing such equipment, you should also count on the fact that each model has its own height. For these options, these parameters are 241, 403 and 552 mm, respectively. The distance between the axles is also different and is equal to 150, 350 and 500 mm for each model. When purchasing heating radiators "Radena", which are sold under the brands CS 150, CS 350, as well as CS 500 / VC 500, you must rely on a certain depth and width of the sections. For the first model, these dimensions are 120 x 74, while for the second and third models, these dimensions are 85 x 80 mm.
Bimetal equipment
The area of use is systems where water is used as a working fluid. It can be equipment for residential or office buildings. As well as industrial enterprises or public buildings.
Radena bimetallic radiator consists of sections connected by steel nipples and paronite (asbestos-free) gaskets.
The versatility of the products lies in the possibility of operating the products either in autonomous systems (low-rise construction), or in "high-rise buildings" where there is centralized heating. The increased heat output possessed by Raden bimetallic heating radiators goes well with other devices for working in low-temperature conditions.
Manufacturing and price
Each radiator includes a number of sections that are connected to one another with steel nipples. Additionally, asbestos-free paronite gaskets are used. Two pipes are inserted inside the equipment - vertical and horizontal. They are needed for the normal passage of the thermal carrier.
The radiator frame made of steel is enclosed in a special shell made of an aluminum-based alloy. The production method is injection molding. The thermal medium does not come into contact with the aluminum body, which prolongs the durability.
The main parts of the radiator.
Since the frame is made of steel and certain rules are followed during its manufacture, it has high strength and resistance to corrosion. The aluminum component solves two problems. First, it increases heat output. Secondly, it reduces inertia.
The method of painting is no different from aluminum products without the use of bimetal. The cost depends on the model. As in the previous case, the products are divided into several types - Bimetall 350 and 500. The price of the first is approximately $ 13.3 per section, the second - $ 14.
Main technical properties
Here we will again take one model as a basis, that is, bimetallic heating radiators Radena Bimetall 350, and if there are any discrepancies, we will focus on the differences. The working pressure is 25 atm, the test pressure is 40, the tensile pressure is 90. The heat output for Bimetall is 135–350 W, Bimetall is 185–500 W.
Radena Bimetall 350.
The maximum temperature that the heat carrier is allowed to reach is 110 degrees. 0.02 mg of oxygen is allowed in a liter of the working medium.With regard to pH, the value ranges from 6-10.5. One section of the Bimetall 350 holds 0.16 liters, the Bimetall 500 - 0.22 liters.
Section weight - 1.52 kg and 1.95 kg for each model, respectively. Height - 403 mm or 552 mm. The center distance is indicated directly in the model name - 350 mm and 500 mm. Radiator section depth - 85 mm, width - 80 mm. The inlet hole diameter is standard 1 in. The color is made in white, which suits almost any interior.
Reviews about the features of "Radena" radiators
produces aluminum and bimetallic radiators. The first of them have a certain form of vertical and horizontal collectors, which are a wide ellipse. This allows for the least resistance to water flow, so the heat transfer from each section is quite good. The collector itself is not experiencing so high loads, this contributes to the extension of the service life and increase in reliability.
The second feature of such batteries is the wall thickness of the vertical tubes, for this manufacturer this parameter is always greater than 1.9 mm. This is not to say that bimetallic radiators are less reliable. In this case, the bimetal is complemented by thick-walled steel collectors. High-carbon steel is used, because of this, the pH value can vary over a fairly wide range, it varies from 6 to 10.5 units.
Features of Raden technologies
Let's talk about aluminum radiators first. Their first and very important feature is the shape of the horizontal and vertical collectors - a wide ellipse. This form creates the least resistance to the flow of the coolant, therefore it passes a lot, and the heat transfer from the sections is good. At the same time, the collector itself experiences less stress, which contributes to an increase in reliability and service life.
The second feature is the wall thickness of vertical pipes: this manufacturer always has it more than 1.9 mm, which is comparable to the thickness of pipes for supplying a coolant. And this is another plus for durability and reliability.
They guarantee warmth and comfort for many years.
Radena bimetallic radiators are equally reliable. It is a complete bimetal, with thick-walled steel manifolds. Moreover, high-carbon steel is used, which is why the pH value can vary over a very wide range: pH from 6 to 10.5.
The third feature: two-stage painting. First, all sections are pre-processed. They are cleaned, then treated with degreasing compounds, preparing the surface for painting. Further, each section inside and outside is covered with a layer of paint (anaphoresis technology). This is corrosion protection. Please note that all surfaces are processed. Inside too. Finding a second campaign that paints the radiators inside will be very tricky. Then another layer is applied on the outside - epoxy powder paint. Spraying takes place in an electrostatic field, which ensures high durability of the coating.
All reviews are positive. It's just hard to believe
The painting is very reliable, does not fade over time and does not change color, does not exfoliate, there is no marriage - this is from the words of the installers. The paint is uniform on all sides. The sections can be disassembled and assembled, while the appearance does not suffer, chips and mother-in-law are not formed.
Further "little things" that add pluses in favor of radiators:
- Intersection gaskets - graphite, self-centering. Therefore, when assembling / disassembling, the radiator is always even. Never flows.
- The thread is deep and even, not filled with paint.
- The ends are always already cleaned. I took it out of the package and can be collected.
- The spinning force is stable, above 50 Nm. Very reliable and high quality build.
- The radiators are packed in bubble wrap, the boxes are reinforced on the sides and corners, so damage during transportation is a rarity.
All these nuances seem insignificant, but they speak of high quality. And all the "little things" give a burst pressure for aluminum radiators - 52-55 atmospheres. The result is a stable clientele and no complaints.
The flow diagram of the coolant in bimetallic radiators with bottom connection
It looks a lot like a promotional article, but the quality is really high. The information given above is not on the official website (partly there is about painting, and that's not all). Apparently, they are trying to protect the subtleties from competitors. The data was taken from the reviews of the installers (on third-party resources).
The popularity of Rodena heating radiators is evidenced by a considerable number of fakes on the market. If you decide to buy this particular brand, or find an official representative, or carefully consider the details of packaging and appearance. These are the stickers in the right place and the correspondence of the barcode.
Additional benefits
Another feature is two-stage staining. At the first stage, all sections undergo processing, they are cleaned, and then degreased, preparing the painting surface. Each section is coated on the outside and inside with a layer of paint that protects the material from corrosion. There are many little things that add up to the benefits of radiators. Users note that the self-centering graphite intersection gaskets provide a complete seal. The carving is not filled with paint, it is distinguished by jealousy and depth. Home craftsmen also note the security of the ends as a plus; after unpacking the battery, you can immediately install it.
Reviews of aluminum radiators of the Radena brand
Aluminum radiators "Raden", reviews of which will allow you to understand whether to purchase this or that model, do not differ in a wide range. They are presented to the attention of the consumer in two modifications, one of them has a center-to-center distance of 350, while the other has a distance of 500 mm. According to users, the price for one section of such batteries ranges from $ 11 to $ 12. Batteries with side connection are made, and for stable operation, an automatic air vent or Mayevsky crane should be installed.
Consumers are advised to install mud traps or filters if the coolant is rich in impurities. It is recommended to install Radena aluminum radiators in private houses heated by an individual system. Here you can adjust the pH and pressure yourself. All users who installed these radiators in apartments note that they face problems that are expressed in frequent pressure changes and the negative impact of impurities in the water on the materials of the product. In addition, due to the change of just one battery, the system can be completely unbalanced, and it will become colder in the apartment. It is necessary to clarify what pressure in the system is normal.
We are looking for problems on the head - cheap manufacturers
Our man is inclined to save money, and I think you are no exception. But it must be done wisely. A well-known proverb says: the miser pays twice.
What can happen if you buy a bimetal radiator that is too cheap? Or will you purchase it from a little-known or dubious supplier?
- Instead of a normal bimetallic radiator, you will be sold a semi-bimetallic one;
- The box of a good brand will contain a fake or Chinese “noname”;
- The internal parts will be made of low-quality steel, which will quickly corrode;
- The copper core will be made of thin-walled tubes that will quickly deteriorate due to poor-quality water;
- Leaks will appear at the joints due to poor sealing;
- The radiator will be manufactured without compliance with the standards, its characteristics will not correspond to the certificates.
Technical characteristics of radiators "Radena" made of aluminum
![radiator radena 500 [1], radiator radena bimetal](https://buildex.decorexpro.com/wp-content/uploads/radiator-radena-500-1-radiator-radena-bimetall.jpg)
Radiator "Radena" 500 is a battery with a distance between the axes of 500 mm. However, this characteristic is not the only one to look out for when buying a device. It is important to take into account that such batteries will function normally at a pH not higher than 9, an indicator of 7 units is considered optimal. The working pressure is 16 atmospheres, but the batteries can withstand up to 50 atmospheres. This reserve should be sufficient for emergency situations. But if serious pressure drops are quite frequent in the system, then it is best to install bimetallic radiators.
Scope of Raden radiators
Made in Italian design, heating appliances consist of separate sections with an annular distance of 350 or 500 mm, which is selected depending on the height of the window sill
... The finned surface of the radiators provides high heat transfer: 165 -192 W aluminum section and 135 - 185 W bimetallic section.
When choosing aluminum or bimetallic heating radiators, you should focus on the characteristics of heating networks.
If the heating system is installed in an individual residential building, where the coolant is supplied from an autonomous boiler, then aluminum
radiators would be ideal.
At the same time, if during the construction of a multi-storey civil building it is envisaged to connect to centralized networks with possible pressure drops and a coolant with alkaline additives, then bimetallic
devices, due to their design, will be more reliable and durable.
Reviews of bimetallic batteries of the Radena brand
You can follow the experience of many buyers and purchase a Radena radiator for your home. Bimetal in its basis will exclude contact of water with aluminum, because the characteristics of central heating systems are far from the norm. Aluminum is a reactive metal and can corrode at high pH levels, leading to leaks.
The second reason, which indicates the advisability of using bimetallic radiators, is expressed in their increased strength. Aluminum and its alloys can be called soft metals, and pressure drops can damage the material. Moreover, some manufacturers are trying to save money by making the walls of the collectors thin. Whereas if steel is used, even of small thickness, then it is able to withstand impressive pressure.
As buyers emphasize, in batteries, steel collectors are connected by welding, a vertical tube is welded into the collector. However, steel has a low coefficient of thermal conductivity, so aluminum is fused onto it to create air duct fins. As a result, it is possible to obtain a bimetallic section, which is characterized by low chemical activity, impressive strength and excellent thermal power.
Considering the radiators "Raden", we can highlight their advantages over the products of many other companies. The latter sometimes produce batteries in which steel is only in a vertical tube. In such batteries, heat transfer is higher, but the coolant is in contact with the material. Not all networks can be used with these products. As for Radena, it produces only full bimetal, using high-carbon steel. According to users, this is why the working pressure of such products is 25 atmospheres, and the warranty period reaches 25 years, and the ambient temperature is equivalent to 100 ° C. The center-to-center distances are 150 and 500 mm. Some buyers are put off by the price of radiators, which is about $ 14, but this cost is justified, because such batteries are ready to last even longer than the guaranteed service life.
Radena bimetal radiators
Bimetallic batteries are available in 4 types.
Raden bimetallic radiators are made of stainless steel and aluminum. The collector (tubes through which the coolant flows) is steel, and the fins are aluminum. This makes the battery very strong and gives off heat well. The sections are connected to each other by steel nipples with paronite gaskets.
There are four modifications:
- CS 150 - 620 rubles / sec;
- CS 350 - 680 rubles / sec;
- CS 500 - 720 rubles / sec;
- VC 500 - 870 rubles / sec.
All experts, without exception, declare that bimetallic batteries are the best choice for any heating system. Especially for those working under high pressure.
As you can see, Raden's bimetallic radiators are not more expensive and not cheaper than other Italian batteries. The letters in the marking indicate the method of connection to the circuit (CS - lateral, VC - lower), and the numbers - center-to-center distance. All models withstand an operating pressure of 25 atmospheres, and a test pressure of 40 atmospheres. The quality of the coolant does not really matter (the upper limit of the pH is 10.6), the maximum temperature is 110 degrees.
The section height depends on the center distance. The depth for all but the CS 150 is 85 mm and the width is 80 mm. The dimensions of the CS 150 low heat exchanger section are slightly different: the depth is 120 mm, and the width is 74 mm.
Gas infrared heating is not suitable for permanent use, except as a temporary measure. like a conventional heater.

Why else is it worth choosing Radena brand heating radiators
Radiators "Radena" have been manufactured in Italy for over 30 years. By purchasing this equipment, you can count on the fact that it is of high quality and is adapted for operation in the conditions of Russia. "Radena" - radiators, the manufacturer of which takes care that the technical conditions of the products correspond to the heating systems of the countries where they are supplied. For example, aluminum radiators manufactured for Russia are capable of undergoing pressures up to 16 atmospheres, which makes it possible to use these batteries even in high-rise construction. In addition, they have an attractive design and modern appearance; they can be integrated into the interior of a room for any purpose. The main finning profile with a rounded top provides injury protection.
Not only quality, but also appearance is an essential advantage of Raden radiators
Positive reviews for Raden radiators are due not only to their mechanical and operational characteristics, but also to their aesthetic appearance, as well as strong packaging that reliably protects radiators from mechanical damage.
The Italian design of the device is complemented by a high-quality anti-corrosion and decorative coating. White powder enamel is applied to aluminum surfaces using electrostatic spraying. When heated, the paintwork does not emit substances that negatively affect human health, and fully complies with the requirements of both domestic and European environmental safety standards.
