The duct heat exchangers KWC are intended for the air heating and cooling in the ventilation and air-conditioning systems. The housings allow the heat exchangers to be connected to the round ducts.
The series of the KWC heat exchangers suitable for the airflows within 250-2000m3/h. The housings of the heat exchangers are adapted for the installation in the round ventilation ducts with the diameter of 160-355mm. In CF and CLF heat exchanger types droplet eliminator and drain gutter are installed inside the housing.
The heaters and coolers are made of copper pipes and aluminium with spacing of 2; 2,4 or 3mm. The terminal connections have internal threads.
