Air Source EVI Heat Pump Description

 1. Safe working at temp down to -25 degree

 2. Adopting the most advanced low- temperature Enhanced Vapors Injection compressor technology. 

3. It has been further optimized to enable heat pumps to efficiently produce water temperature up to 60DC during cold winter time.

EVI Heat Pump Features:

1. EVI air to water heat pump is specially designed for house heating in cold area. The ambient temperature range is -25DC to 43DC. It can use safely in -25DC ambient.

 2. Normal heat pump is difficult to heat below -5 DC. EVI technology importantly increase refrigerant flow of the main loop and outside evaporation enthalpy difference brings 7% to 34% additional heating.

 3. A strong low-temperature heating capacity.

4. EVI heat pump significantly improves the problem of insufficient flow of refrigerant in low-temperature environment by the secondary compressor suction, making it will be useful even if the outdoor temperature is as low as -20DC and without obvious thermal decay problem.
