Air to water commercial heatpump water heaters for low temperature ambinet
Air to water evi heat pump
Adopting the most advanced low- temperature Enhanced Vapors Injection compressor technology.
Adopting Eco friendly refrigerant R407c&R417A
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 -20DC 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.
5. Package
The qualified heat pump is packaged by especial designed cartoon or fumigation wooden frame before send to our warehouse, avoid hitting.
Services:
Supply OEM service for customers.
Produce heat pump according to customer's special demands.
Supply free spare parts according to order quantity.
Long warranty period.
