Outdoor Air Chiller
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
Air-cooled screw type cold (hot) water unit 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.
GRAD air-cooled screw cold (hot) water unit embodies the essence of design, manufacture and application, the unit has low temperature, strong heat, multiple protection Freezing, intelligent defrosting, intelligent control and other core technologies, high operational reliability, wide range of operation, product diversity, widely used in hotels, shopping malls, office buildings,exhibition halls, airports, stadiums and other public places, and can meet the electronic,pharmaceutical, biological, textile,Chemical industry, metallurgy, electric power, machinery and other industries.

● 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.
Low temperature strong hot air cold screw cold (hot) water units | Ultra-low temperature strong hot air cooling screw unit operating range | |||
| Refrigerant type | Mode | Air side ambient dry bulb temperature(°C) | Outlet temperature range(°C) |
R22 | heating | -35~-21 | 35~-55 | |
R134a | heating | -35~-21 | 35~-70 | |
refrigeration | 21~-45 | 5~15 | ||
The perfect combination of single-machine two-stage compression technology and strong qi supplementing enthalpy
Stable operation at the ring temperature of -35, up to 70 hot water; -35 operation can ensure the effluent temperature of 60;
Internationally recognized environmental refrigerant R134a is available for selection, low ring temperature and efficient operation, the ambient temperature is -12 , compared with the hot gas boiler And electric boiler energy efficiency increased by 180%. Mainly used in northeast,northwest heating energy station, industrial high temperature process and other occasions.
