—— Product Description ——

Withair® DC Inveter Heat Pump is a very intelligent heat pump system with flexible capacity output. It could adjust heating capacity output automatically according to requirements.It is much more energy-saving with a long lifespan.

Withair® DC Inveter Heat Pump provides energy-efficient room heating and domestic hot water for residential and small commercial application. Using free renewable energy from the air ,the units are highly efficient with low running costs, low carbon emission and are able to be integrated with energy systems such as solar heater and boiler.

—— The key advantages Include ——

● Running ambient range from -27℃ to 43℃.
● DC inverter technology to sure heating capacity “0” loss when ambient temperature.>-15℃.
● 10~120rps inverter technology to fast  higher water temp. as room load ( accordingly suddenly cold weather).
● Intelligent defrost totally.
● Digital LED display pressure: built-in high & low pressure sensor.
● Built-in hydraulic module for your option.
● 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.
● Hydrophilic and corrosion-resistant material ensures adaptability to poor weather. 
● Advanced & world-famous inverter compressor high-efficiency, low-noise and low-vibration operation.
● Remote monitoring and control features enable the unit’s operational schedule to be set via internet or phone.

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

● 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 the cold temperature.

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

● Heat recovery function provides free hot water using heat removed from room during cooling.

● Remote monitoring and control features enable the unit’s operational schedule to be set via internet or phone.

● 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.

● Standalone subsystems enable maintenance of individual subsystems without affecting the continued operation of the rest.
● Unique heat exchanger protection technology,increases heat exchange efficiency to 30% above that of conventional heat exchangers.

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