Domekt R 300 V is a compact ventilation unit with vertical connection and heat recovery for ventilation of residential areas. The maximum air capacity of the R 300 V is 289 m³/h, which is enough for a room of up to 110 m² with a ceiling height of up to 2.6 m. The installation dimensions are only 598x502 mm, and the maximum power consumption of the EC fan is 72 W.
Domekt R 300 V is equipped with a rotary heat exchanger (recuperator), which allows maximum saving of electrical energy. The rotary recuperator operates on the basis of thermal energy accumulation. A rotating aluminum cylinder with channels heats up when warm air passes through it, and when cold outside air passes through, it is heated by stored energy. For example, if the air taken from outside is -20.0°C and the air removed from the room is +22.0°C, the temperature of the fresh supply air will be +16°C.
