SPRSUN
SPRSUN EVI air source heat pumps are designed for domestic/commercial hot water and house heating in cold areas where lowest air temperature is above -25℃.
● Efficient and Energy-saving
Air source heat pumps absorb 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 heaters, saving a lot of electric costs for users.
● Green and Environmental Protection
By using air hot energy and electric energy, there is no harmful gas being discharged during the operation of heat pumps.
● 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 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 cabinets we are using are made of GALVANIZED STEEL, making them more rust resistant, durable and affordable.
● 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; LCD screen digital controller for automatic operation
● Convenient
The EVI heat pump is easy to install in many places, such as garage, balcony, kitchen, etc.
Rated working condition: dry-bulb temp: 20℃; wet-bulb temp: 15℃; cool water temp: 15℃; hot water temp: 55 ℃.

SPRSUN EVI air source heat pumps can be applied for hot water and floor heating.
Wide Range of Applications: these EVI low temperature heat pumps could meet the hot water and house heating requirements of different places, such as villas, houses, schools, factories, hotels, hospitals, spa centers, sauna centers, greenhouses, flower gardens, farms, etc.
Why can SPRSUN EVI heat pumps work at -25℃?
Because of the Enhanced Vapor Injection (EVI) technology from Copeland compressor with crankcase heater for special cold areas, SPRSUN designed EVI gas piping system and controlling system make EVI air source heat pumps work stably in the low temperature condition.
Our EVI air to water heat pumps adopt high quality components, such as Copeland enhanced vapour injection (EVI) technology compressor, Danfoss electronic expansion valve and Eaton AC contactor and thermal relay.
It is easy to install SPRSUN EVI air to water heat pumps, shown as the following Installation Diagram:
