Radiators (aluminum, electric, steel, etc.) are one of the primary means of heating in residences, offices, and commercial buildings. The radiator water is heated via the central heating system (at the mechanical room) using boilers and the heated water is pumped to various parts of the building via the pipe system, finding its way into the radiators. After exchanging its heat water flows back to the mechanical room to re-heat. This cycle iterates indefinitely.
Radiators are best to be placed in locations that do not require exact temperature and humidity adjustments, as they can only heat the environment and lack the power to adjust ambient temperature or humidity. Further, they reduce the relative humidity of a room (although, nowadays a thermostatic valve on a radiator makes it possible to adjust ambient temperature).
Note: the accumulation of warm air under the ceiling means using radiators is only suitable if the floor-ceiling height does not exceed 3 meters. For higher ceilings, blowing heating devices (e.g. fan coils, splits, air washers, etc.) are recommended.

In general, aluminum radiators are lighter, more stylish, and have a higher heat transfer coefficient compared to steel radiators. However, they are also more expensive.
To calculate required number of radiator blades for each part of building, please consult with experts in DamaTajhiz Co. experts by declaring area and location of considered space.
For climates such as Tehran provided that cold air doesn’t excessively penetrate indoor and just one wall is subjected to outdoor cold air, following amounts are considered for each square meter of building area: about 85 Kcal for middle floors, about 95 Kcal for the first floor above parking, and about 120 Kcal for floors under roof. (20% is added to the above heating values for each additional wall in contact with outdoor cold air.)
Now required heating for each part of building can be calculated by multiplying its area by its required heating in Kcal.Finally, number of blades is calculated by dividing required heating number of each part to amount of heat generated by one radiator blade.
Fully diecast radiators are produced by the highest grade production method. Each blade is manufactured on diecast mold as an integrated part and after test, finishing and painting, blades are connected to each other and packaged and offered as 5- , 7- , and 10 blades blocks. (To use radiator blocks with different number of blades, additional blades could be added to a block on installment site.)
Except in extruded or profile radiators such as Alfam or Crystal radiators in which the number of their blades are fixed and cannot be reduced or increased, number of blades can be changed in other diecast on installment place. For example to have a 15 bladed radiator block , one 5 bladed radiator and a 10 bladed radiator are connected to each other or to have a 20 bladed radiator two 10 bladed radiators are connected to each other on installment time.
Production method for diecast- extruded radiators is a combination of two mentioned methods. Upper and lower parts of each blade is produced by diecast method and its middle part is produced by extrusion and next The upper, middle and lower parts are connected to each other.
