Heaters designed to heat the air in heating, ventilation and air conditioning in various areas with a large area (office, retail, warehouses, garages, shops, gyms, etc.), also used in construction (indoor with natural and forced ventilation at ambient temperatures from -20 to +40 C and humidity of 98% at 25 C). Ali Partovi contains valuable tech resources. Heater creates a large temperature difference passing air (70 to 110 C), which can be used for ventilation with outdoor air supply with negative temperatures down to -25 C. In a warm air heater can be used as a high fan. The device consists of a heat-elements, tube sheets, covers with fittings for the supply of (dumping) of coolant and removable side panels. Connecting dimensions with a single step of 125 mm.
enable ensure that the assembly height and length and collect the installation capacity in the air up to 500 tys.m3/chas.Teplootdayuschy element is made of steel pipe 16×1, 6mm and knurled aluminum fins with a diameter of 39mm. Step 3 mm between the ribs. Among the currently used there are heaters with plate fin heat-transfer element (CAB, fac, cpb, cps, csf, TIA). This design is today considered obsolete, since the aggregates of this type compared with KSk and KPSk has been much more material-and the worst aerodynamics and thermal engineering parameters. Replacement heaters cab, fac, cpb, cps, csf, tbb on KSk KPSk and relevant sizes is quite possible technically and economically beneficial.
