Product Overview


—— Product Description ——


Withair® EVI Air Cooled Scroll Heat Pump adopts the most advanced low-temperature enhanced vapors injection compressor technology, EVI heat pump delivers higher heating capacity at low evaporation temperature thereby better responding to heating requirements than normal air source heat pumps.(EVI compressor-enhanced vapor injection,Vapor-injected method can effectively improve heat capacity, prevent higher discharge temperature of compressor and guarantee operating stability of unit at low temperature).


Withair® EVI Air-Cooled Heat Pump Unit can supply hot water and heating for large buildings in cold climate region and be widely applied to civilian projects and industrial projects,such as hotel, villa,restaurant, hostital, factory,etc,. it is a wise choice for areas where water is insufficient or therre are strict limits on  noise level and surroudings.


—— The Key Advantages Include ——


● ECO friendly refrigerant R410A,R407C.

● Built-in hydraulic module for option.

● Intelligent defrost totally.

● Super heating capacity: latest enhanced vapor injection Copeland(EVI) for extremely cold climate, reliable operation and meet the demand of heating of the cold region.

● EVI unit rated heating capacity is 15% higher than normal unit, higher 10% COP; under - 10℃ temperature, heating capacity is 20% higher than the normal unit, higher 25% COP.

● The independent design and manufacturing of high efficiency shell and tube heat exchanger of water side, strong energy saving and anti-freeing.

● The innovation of the split type design, put water system indoor, which solved the frozen damage problem of water side heat exchanger at the cold region in winter.

● Use SWEP auxiliary plate heat exchanger with condensate super-cooling degree, low temperature heating effect significantly.

● Electronic expansion valve throttle control, refrigerant flow control precision at at the cold temperature.

● Air side heat exchanger with anti-ice system design, prevent heat exchanger to frost at the cold temperature.

● Multi self-protection  functions, such as: high & low pressure, high temperature, water flow and antifreeze protection.

● Modular networking technology, the operation of individual modules can be coordinated according demand.

● Advanced & world-famous hermetic scroll compressor high-efficiency, low-noise and low-vibration operation.

● Standalone subsystems enable maintenance of individual subsystems without affecting the continued operation of the rest.

● Hydrophilic and corrosion-resistant material ensures adaptability to poor weather. 
● Uses advanced hermetic scroll compressor high-efficiency, low-noise, and low-vibration operation.
