Air Chiller Unit

The GRAD Air Chiller Unit is equipped with a self-developed NB-iot Internet of Things remote intelligent control module. It can be operated via a mobile phone APP, eliminating the need for dedicated personnel to stand by. It offers fault early warning prompts and online diagnosis. It can operate efficiently in an ambient temperature range of -30℃ to 43℃, with a maximum water outlet temperature of 60℃. It has various terminal forms and is suitable for radiator, floor radiant, central air conditioning cooling and heating. The national patented intelligent defrosting technology accurately detects frost, quickly defrosts, significantly reduces the frequency of defrosting, and greatly shortens the defrosting time. In addition, this unit also has unique advantages such as modular customization, no need to build a machine room, environmental protection and energy conservation, high efficiency and low noise, and wide application range.

Product function
