SPRSUN EVI air source heat pumps are designed for domestic/commercial house heating and cooling 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:
- Heating: air temp (DB/WB): 7℃/6℃; water temp (inlet/outlet): 40℃/45℃;
- Cooling: air temp(DB/WB): 35℃/24℃, water temp (inlet/outlet): 12℃/7℃.
EVI air source heat pumps are designed for house heating and cooling. User can change the working mode by operating the wired panel of the controller. Compressor starts/stops according to return water temperature. When all rooms reach preset temperature by room thermostat, the heat pump will be turned off through linkage switch.

Wide Range of Applications: these EVI low temperature heat pumps could meet the heating and cooling 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:

What is an EVI Heat Pump?
The term EVI stands for Enhanced Vapor Injection. It is a kind of advanced technology used on a heat pump to supply heating solutions for severe cold winters, such as space heating, cooling, and domestic hot water. Due to the adoption of EVI compressor technology, the EVI heat pump can meet the higher COP demands at relatively low-temperature conditions. In addition, the eco-friendly and high-efficiency refrigerant makes the pump work stably in severe cold places where the lowest air temperature will reach -25°C.
EVI Heat Pump’s Working Principle
In general, a traditional heat pump distributes the accumulated heat from the ambient environment from one place to another. The EVI heat pump performs the heating and cooling heat pump activities on electricity and effectively transfers heat from one place to another with less time when compared with other heat pumps. It is verified to be an energy-saving and cost-effective way after a long period using.
Reasons to Choose EVI Heat Pump
EVI heat pump provides countless reasons and benefits that attract you to choose them over any other traditional or ordinary unit in the market. Among the various merits the heat pump provides, the following are a few of the significant reasons that make an EVI heat pump a must-have product for you:
√ It is resistant to Extremely cold weather, as the EVI technology adopts humanized settings and intelligent adjustments to ensure the environment doesn’t affect the equipment.
√ It provides smooth and stable running under extremely low-temperature conditions such as -25°C.
√ It has high working efficiency and a built-in automatic defrosting functionality, which takes only 2-3 minutes to get done completely.
√ The compressor has an anti-noise feature that makes it less loud.
√ It contains an R32 refrigerant, which acts as a low global warming element and hence makes it more environment friendly with fewer carbon emission particles.
Major Applications of EVI Heat Pump
The EVI heat pump is formulated with advanced technology to provide unparalleled heating and cooling functions at places where the minimum low temperature is -25°C. Nonetheless, it is equally sufficient to keep any residential area hot in cold weather, like houses and villas. Apart from that, an EVI heat pump can even perform perfect heating and cooling heat pump activities for even greater commercially civilized places, including corporate buildings, factories, hotels, restaurants, hospitals, schools, spa and sauna centers, greenhouses, and others.
