Heat Pump Features

EVI High Temperature Air Source Heat Pumps


SPRSUN EVI High Temperature Air Source Heat Pumps are designed for commercial/industrial hot water heating with lowest air temperature above -10℃.


  • Efficient and Energy-saving 

Heat pump absorbs hot energy from the air freely, and the electricity is only used to drive the compressor to pump up the heat from the air, so it consumes just a quarter of traditional electric water heater, saving lot of power for the user.  


  • Green and Environmental Protection

By using air energy and electric energy, there is no harmful gas being discharged during the work of heat pump. R134A refrigerant guarantees fluoride-free emission. 


  • Usable All-weather

All weather operation: stable operation without being influenced by any windy, rainy or snowy weather. 


  • Endurable 

The Enhanced Vapor Injection (EVI) technology from Copeland compressor, Danfoss Electronic expansion valve, Eaton AC contactor and thermal relay and other brand components of the heat pump guarantee high quality and a long lifespan.   

All of our screws and clips (both external and internal) are stainless steel. The cabinet we are using is made of  GALVANIZED STEEL, making them more rust resistant and durable.


  • Multiple Protections

For example, if water flow is not enough in the system, the system will show high pressure protection and stop the heat pump automatically to protect the compressor from being damaged. Also, there is high current protection: if the power supply is not stable, the heat pump will show the high current error to stop the heat pump and avoid compressor damage


  • Linkage Function

External signal on/off function


  • Guaranteed Safety

Complete isolation of water and electricity avoids electric shock, explosion and poisoning.
