Air source high temperature hot water unit for extreme cold working condition
Air source high temperature hot water unit for extreme cold working condition
Ultra-low temperature operation, ultra-hot water
The ultimate solution for direct replacement of boilers
Modular design
This series adopts the modular design, using NKYR30H, NKYR40H and NKYR50H as the basic module units that 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 heating range from 30KW to 800KW.
IP intelligent protection
Energy –efficient, green and environmentally friendly
The unit adopts world-famous compressor that has energy efficiency up to 4.0 or more, using three kinds of clean energy, solar energy, air heat energy and electric energy, and producing no environmental pollution caused by the use of fossil fuels such as oil, coal and gas. There is no harmful gas emitted during the work process. It is no need for users to worry about health even if they take shower in a confined room.
All weather use
The unit absorbs not only solar energy but also energy from the air. Therefore, it is not affected by bad weather such as cloud, rain or snow, but can be used 24 hours a day, making up for the shortness of common solar water heaters that are affected by the weather and cannot guarantee the supply of hot water all 365 days of the year.
Easy to install and operate
The unit is extremely easy to install and is not subject to environmental restrictions. There is no need for special care or dedicated machine room. The original intelligent network system enables a full-automatic operation by a single press, no need of special management. In addition, it has advanced automatic fault-detection function and is easy to maintain.
Ultra-low temperature, ultra-high temperature
The lowest ambient temperature for safe operation is -35°C, and the highest outlet temperature is 85°C. It is beyond the operating range and outlet temperature of traditional air source heat pumps, and can effectively work in extremely cold areas to completely solve the heating problem in northern regions in winter.
