Termofan heat recovery units with heat pump, designed for saving energy and also improving indoor air quality. TF-DXHR units provide heat recovery and well conditioned fresh air by air to air plate type exchanger and heat pump. 30°c fresh air in the summer time and 12°c fresh air in the winter time can be obtained by usual heat recovery units but these results are not comfortable. You can obtain 20°c fresh air in the summer time and 25°c fresh air in the winter with high efficiency heat pump.
