Low temperature air source module unit
Low temperature air source module unit
Ultra-low temperature operation, perfect heating solution
Suitable for heating in houses, villas, schools, communities, hotels, office buildings and other places
Modular design
Modular design, compact structure and flexible combination: Modular design concept is adopted. Each module can be used alone, or any 1 to 16 basic modules can be combined freely into a complete set as capacity required to extend the cooling capacity from 35KW to 1088KW for different users
Green and environmentally friendly
The jet boosting technology has subverted the traditional heating modes by boilers and electric heaters in most northern parts of China. It is safe and environmentally friendly, no need of fuel such as oil, gas, coal or liquefied petroleum gas, free of harmful gas emissions, no fire or explosion hazards, and no damage to the surrounding ecological environment.
Leading EVI technology, powerful heating and cooling capabilities
The unit is equipped with the world-leading and efficient EVA (Enhanced Vapor Injection) compressor; the low-temperature unit applies the second-generation high-temperature jet boosting technology, enabling the air conditioner to be heated at an ambient temperature of -25°C where the heat attenuation is reduced by more than 15% compared with common air-cooled heat pump unit.
Cloud technology
Cloud - Information Age of Intelligent Air Energy
Through the network data master center, the user can remotely control the unit anytime and anywhere. The service center technicians can adjust the unit to optimal operation status according to climate change, and can also query the unit operation records to perform daily maintenance. It is really convenient!
