High efficiency and energy saving - high efficiency, long service life,

more than 75% of energy can be recycled

efficiency becomes a reality

Easy maintenance - the heat exchanger has a side-out design for easy replacement and repair 

A wide range of air volume

Heat and moisture exchange – it can recyele more than 75% of the energy in the exhaust, exchange temperature and humidity with fresh air, reduce load of the air conditioning, and greatly reduce energy consumption

Efficient and durable heat exchanger core -The heat exchanger core adopts special flow channel design, ER special paper + ABS plastic.

The Mortise and tenon joint structure improves heat transfer efficiency and can be used for 10 years. Ordinary corrugated paper can only be used for 3 years

Silent operation.
