EVI Air source heat pump is designed special for
domestic/commercial hot water and house heating 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.
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;
This water heater is easy to install in many places, such as the garage, balcony, kitchen etc.
EVI air source heat pump (for DHW and/or house heating) is designed for domestic/commercial hot water and/or house heating, with 3 way valve, heat pump controller can change the circulating direction of water between hot water tank and house heating system, and hot water ispriority.
Wide Range of Applications:which could meet different places’ requirements, villa ,family, school, factory, hotel,
hospital, spacenter,sauna center,water park 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
Our EVI heat pump used high quality components,such as Copeland Enhanced vapour injection
(EVI)technologh compressor,Danfoss Electronic expansion valve and Eaton AC contactor and
It is easy to install related EVI heat pump as below Installation Diagram .
