High-efficiency Heat Exchanger:
Counter-flow on both air to air/air to refrigerant side, up to 1.6 times cooling efficiency than shell and tube heat exchanger.
Smaller dimension, 30% less power consumption, more stable pressure dew point, compared with shell and tube heat exchanger.
4 ~15 bar working pressure, customizable.
Never get rusted: made of stainless steel or aluminum, and the rest part that contacting compressed air is made of 304S stainless steel, which never results in getting rusty problem as shell and tube type.
