In the conventional drying process of wood, the traditional ventilation method results in significant heat loss due to the removal of moisture and exhaust gas. The forced ventilation and waste heat recovery system in the wood drying room is a new technology that improves the indoor and outdoor dry wet air exchange process in drying production and effectively recovers waste heat.

The counterflow plate heat exchanger adopts high-quality hydrophilic coated aluminum foil, epoxy resin coated aluminum foil and other materials. The two air streams enter the channel in reverse, increasing the heat transfer area. The fresh air and exhaust air are completely separated to avoid the transmission of odors and moisture. Fast thermal conductivity, no secondary pollution, achieving ventilation and heat recovery functions.
