EVI air source heat pumps are designed for domestic/commercial hot water and house heating system 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. R407C refrigerant guarantees fluoride-free emission.
● Usable All-weather
All weather operation: stable operation without being influenced by any windy, rainy or 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 cabinets we are using are made of GALVANIZED STEEL, making them more rust resistant, durable and affordable.
● Multiple Controller and Protection
High pressure, low pressure, overheating, overload anti-freezing, phase sequence, discharge temperature, suction temperature and so on.
Controlled by multiple controller or by computer (optional)
● 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
The EVI heat pump is easy to install in many places, such as garage, balcony, kitchen, etc.
SPRSUN EVI Air source heat pumps can supply domestic/commercial hot water and/or house heating for cold climate. With 3-way valve, the heat pump controller can change the circulating direction of water between hot water tank and house heating system, and set hot water as priority.
Wide Range of Applications: these EVI low temperature heat pumps could meet the hot water and heating requirements of different places, such as villas, families, schools, factories, hotels, hospitals, spacenters, sauna centers, water parks, 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 heat pump 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 heat pumps, shown as the following Installation Diagram:
