Specification of DC motor Ventilation Unit HRV

Electric Control  of DC motor Ventilation Unit HRV

Cross counter flow plate heat exchanger  of DC motor Ventilation Unit HRV

It is made of ER paper which has high moisture permeability, good air tightness, excellent tear resistance, and aging resistance. 

Two air streams pass through counterly, and increases the heat exchane area in a large degree.  Thus, the efficiency is much more higher.  

Saving your running cost further, reducing air conditioning load

Costs reduce by 30% per year than conventional AC motor ERVs.
