Heat exchanger of XHBQ(X)-TG series HRV

ER paper enthalpy heat exchanger (for XHBQ-TG series)

Heat exchanger of XHBQ(X)-TG series HRV is made of ER paper which is featured by high moisture permeability, good air tightness, excellent tear resistance, and aging resistance. The clearance between the fibers is very small, so only the moisture molecules of small diameter can go through, the odor molecules of larger diameter are unable to pass through it. By this means, the temperature and humidity can be recovered smoothly, and prevent the pollutants infiltrating to the fresh air.

Aluminum sensible heat exchanger (for XHBX-TG series)

Sensible heat recovery air to air heat exchanger is used in comfortable air conditioning ventilation system and technical air conditioning ventilation system. Supply air and exhaust air totally separated, heat recovery in winter and cold recovery in Summer. Two neighbor aluminum foils form a channel for fresh or exhaust air stream. Heat is transferred when the air streams flow crossly through the channels, and fresh air and exhaust air is totally separated.
