AHU’s are composed of fan-driven supply and exhaust air channels, and an energy-efficient heat exchanger. Using Kesair air handling units means, that rather than losing your precious indoor heat to exhaust air, you benefit by its heat to the indoor air.
The supply air is first filtered and then heated with water-filled radiators or with electric heaters. Filtering protects You from harmful particles and air pollution from outside. Supply air cooling, on the other hand, makes the inside air comfortably cool in hot summer months.
Kesair uses three types of heat exchangers in their air handling units; fixed plate heat exchangers, rotary thermal wheels or run around heat recovery system with glycol coils. Air handling units can also be constructed such, that they merely rotate the indoor air without replacing it. This actualizes through a set of specific dampers that lock the airflow in the desired area. In this situation, only a portion of the indoor air is replaced with outdoor air.
