EVI air source heat pump ( heating and cooling) is designed special for house heating and cooling 

system in the air conditioner market where lowest air temperature is above -25℃.

 ● Efficient and energy-saving 

 Heat pump absorb hot energy from 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 the traditional electric heater, saving lot of electric cost for the user.  

 ● Green and environmental protection

    By using  air hot energy and electric energy,there is no harmful gas being discharged during the work of heat pump.

    R407C refrigerant guarantee fluoride-free emission. 

 ● Usable all-weather

    All weather operation: stable operation without being influenced by the windy, rainy and snowy weather. 

 ● Endurable 

   The Enhanced Vapor Injection (EVI) technology from Copeland compressor with crankcase heater for special  cold

   area,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 dur


  ● Multiple controller and protection

    High pressure,low pressur,overheating,overload anti-freezing,phase sequence,discharge temperature,suction tem-

    perature and so on.

    Controlled by multiple controller or by computer(optional)

 ● Linkage function

    External signal on/off function

 ● Guarantee Safe

    Complete isolation of water and electricity avoid electric shock ,explosion and poisoning; LCD screen digital controller 

    and full automatically;


 ● Convenient: 

    This water heater is easy to install in many places, such as the garage, balcony, kitchen etc. 


EVI air source heat pump  (for house heating and cooling)    is designed for house heating and cooling, user can 

change the working mode by operating wired panel of controller.Compressor start/stop according to return water 

temperature,when all rooms reach preset temperature by room thermostat,  heat pump will be turned off through 

linkage switch. 

Wide Range of Applications:which could meet different places’ requirements, villa ,family, school, factory, 

hotel, hospital, spacenter,sauna center,water park,greenhouse, flower garden and farm, etc. 


Why it can work at -25℃? 

Because of the Enhanced Vapor Injection (EVI) technology from Copeland compressor 

with crankcase heater for special cold area,   SPRSUN designed EVI gas piping system 

and controlling system, make EVI air source heat pump can work stably in the low tem

-perature condition.
