Radiators
Radiators of water heating or, as otherwise called, batteries are familiar to everyone. It is this device that keeps our houses warm in winter. Progress does not stand still and a new generation, aluminium bimetallic and steel panel radiators, has come to replace the cast iron monsters of the Soviet period.
The choice of radiators is carried out basing on the working pressure the radiator is intended for, as well as its thermal capacity and the radiator type.
Steel Panel Radiators
Steel panel radiators are made from two steel plates of 1,25mm width and are connected by means of welding.
The large plate surface increases heat radiation of the radiators.
The radiators are usually covered with a casing that makes the radiator look elegant and austere. Such radiators function under the pressure up to 10 atm, emit up to 20-25% more heat, and cost as little as aluminium sectional radiators.
Besides the standard installation package provided together with the radiator, there is a wide range of packages that allows installing them on the floor with the regulation of the distance from the floor.
Aluminium Sectional Radiators
Aluminium sectional radiators are elegant, light, with high heat emission, and they are quite popular in the Armenian market.
Aluminium has got a high level of heat conduction (3-4 times higher than cast iron and steel), and this allows to make radiators with high level of heat emission at rather small sizes. Radiator length (and, correspondingly, their capacity) is easy to increase by means of changing the number of sections used. Each section has got top and bottom collectors joined by a vertical channel and special elements (gills) that increase the surface and, accordingly, heat emission.
Besides a high level of heat emission, aluminium possesses features that allow getting very hard forms of products by creating the elements through foundry. This gives the designers an opportunity to create any and even the most refined design of radiators.
Sectional Bimetallic Radiators
Bimetallic sectional radiators successfully combine in them the features of sectional aluminium and steel radiators: resistance (they can stand pressure up to 40-50 atmospheres); durability (service life – up to 20 years), and a high level of heat emission in combination with modern design.
In bimetallic radiators two metals are used: steel and aluminium.
The steel mandrel strengthens the radiator construction. Due to it, they can stand a high pressure. In addition, the steel filling reacts to water alkalinity more “calmly” than others (ph-factor).
Aluminium possesses a high level of heat conduction, which, in its turn, considerably increases radiator heat emission and reduces its inertness. Such a heating device warms up and cools more quickly.
