Air Cooled Water Chiller
Air Cooled Water Chiller is based on air as a cold (hot) source, water as a refrigerant, it can be cooling and heating, and can run all year round, with environmental protection, energy saving, comfortable, stable characteristics.
The GRAD Air source heat pump 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 and does not require dedicated personnel to stand by. It also features fault prediction Warning alerts and online diagnosis. It can operate efficiently in an ambient temperature range of -30 ° C to 43 ° C, with a maximum water outlet temperature of 60 ° C. It comes in various terminal forms and is suitable for radiators and floors Radiation, central air conditioning for 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.
