Radiators "Radena" - is equipment of increased strength for heating. To date, these units are one of the most popular on the market. And this can not be called an accident or luck. After all, the batteries of this manufacturer have earned popularity due to their high quality, as well as their long life. These products consist of separate sections, which have paronite gaskets and steel nipples for connection. The inside 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 the 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
The Radena bimetallic radiators sold in sectional products are designated as CS 150, CS 350, and 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, this can not 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 W.
Dimensions
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 radiators "Radena", which are sold under the brands CS 150, CS 350, as well as CS 500 / VC 500, you must count on a certain depth and width of sections. In the first model, these dimensions are 120 x 74, and in the second and third - 85 x 80 mm.
Reviews of the features of the Radena radiators
Manufacturer "Raden" produces aluminum and bimetallic radiators. The first of them have a certain shape of the vertical and horizontal collectors, which are a wide ellipse. This allows you to provide the least resistance to water flow, so the heat transfer in each section is quite good. The collector itself experiences not so high loads, this helps to extend the service life and increase reliability.
The second feature of such batteries is the wall thickness of vertical tubes, this manufacturer always has this parameter greater than 1.9 mm. This is not to say that bimetallic radiators are less reliable. Bimetal in this case is complemented by thick-walled steel manifolds. High-carbon steel is used, the hydrogen index due to this can vary over a fairly wide range, it varies from 6 to 10.5 units.
Additional advantages
Another feature is a two-stage staining. All sections at the first stage are processed, they are cleaned, and then degreased, preparing the staining surface. Each section inside and out is covered with a layer of paint that protects the material from corrosion. There are many small things that add advantages to the radiator manufacturer "Raden". Users note that self-centering graphite intersection gaskets provide complete tightness. The thread is not flooded with paint; it is distinguished by jealousy and depth. Home masters also note the end face protection as a plus, after unpacking the battery, it can be installed immediately.
Reviews on aluminum radiators brand "Radena"
Aluminum radiators "Radena", reviews of which will allow you to understand whether it is worth buying a particular model, do not differ in a wide range. They are presented to the attention of the consumer in two versions, one of them has a center distance of 350, while the other has 500 mm. According to users, the price for one section of such batteries varies from $ 11 to $ 12. Batteries with side connection are made, and for stable operation it is necessary to install an automatic air vent or a Mayevsky cock.
Consumers are advised to install sumps or filters if the coolant is rich in impurities. It is recommended to install Radena aluminum radiators in private homes that are heated by an individual system. Here you can adjust your pH and pressure yourself. All users who installed these radiators in apartments note that they are faced with problems that are expressed in frequent pressure changes and the negative impact of impurities in water on the product’s materials. In addition, due to the change of only 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.
Technical characteristics of Raden radiators made of aluminum
Radiator "Radena" 500 are batteries in which the distance between the axles corresponds to 500 mm. However, this characteristic is not the only one that you should pay attention to when buying a device. It is important to consider that such batteries will function normally at pH no higher than 9, an indicator of 7 units is considered as optimal. The operating pressure is 16 atmospheres, but the batteries can withstand up to 50 atmospheres. This stock 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.
Reviews about bimetallic batteries of the brand "Radena"
You can follow the experience of many buyers and purchase a Radena radiator for your home. Bimetal based on it will exclude contact of water with aluminum, because the characteristics of central heating systems are far from normal. Aluminum is a chemically active metal, at a high pH it can corrode, which leads to leakage.
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 of even small thickness is used, it is able to withstand impressive pressure.
As buyers emphasize, in the 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 deposited on it to create the edges of the ducts. 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 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. These products may not be used on all networks. As for Radena, it produces only full bimetal, while high-carbon steel is used. According to users, that 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. Center distances are 150 and 500 mm. Some buyers are repelled by the price of radiators, which is about $ 14, but this cost is justified, because such batteries are ready to serve even more than the guaranteed lifetime.
Why else is it worth choosing radiators of the "Radena" brand
Radiators "Radena" have been manufactured for more than 30 years in Italy. By purchasing this equipment, you can count on the fact that it is of high quality and adapted for operation in Russia. "Radena" - radiators, the manufacturer of which ensures 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 pressure up to 16 atmospheres, this allows the use of these batteries even in high-rise construction. In addition, they have an attractive design and modern appearance, you can enter them in the interior of the room for any purpose. The main fin profile with a rounded top ensures safety.
Conclusion
Today, quite often you can hear allegations that the aluminum radiators "Radena" are not very suitable for installation in a central heating system. But the manufacturer also took care of this. He provided additional corrosion protection by the special treatment of the alloy, which reduces the zinc content in the material to a minimum. Thus, aluminum radiators are suitable for systems in which the pH level of water varies from 6.5 to 9.
