Hydroponic Cooler
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.
● Large diameter heat exchanger, low temperature operation effectively reduce refrigerant flow resistance, increase evaporation pressure, inhibit frost;
● Large distance aluminum foil design, low temperature operation effectively reduce air flow resistance, increase evaporation pressure, inhibit frost;
● Fin flow independent control, accurate control, more thorough defrosting;
● Concentrated a variety of innovative technologies, distributed defrosting system and piston type four-way directional valve effectively avoid the suction of traditional air-cooled heat pump units With liquid, defrosting incomplete, four way directional valve stuck and so on.
Product advantage
1.Free of machine room, less initial investment.
Installed outdoors, no need to build a separate room, no need cooling towers, no need to drill Wells or bury pipes, thus reducing the initial investment of the user.
2. High efficiency, energy saving, environmental protection and safety
Air-cooled screw cold (hot) water unit compared with electric heating can save electricity 75%. Compared with traditional boiler equipment, no combustion,Burning, no exhaust emissions, no flammable and explosive safety hazards.
3. Wide range of operation, strong applicability
According to different needs, a variety of models are available, it can be stable heating operation at -35 ° C ambient temperature, at -30 ° C ~ 48 ° C Stable cooling operation at ambient temperature
4. Intelligent control, no need for special duty
Intelligent control system monitors the operation status of the unit in real time, and automatically adjusts the energy of the unit according to the actual load demand, without the need for special duty, saving labor cost.
5. Multiple protection functions to ensure reliable operation of the unit
With multiple protection function, when failure, real-time automatic alarm
