 Performance 
 

The water-cooled screw chiller adopts the high efficiency double screw compressor of international famous Brand and original refrigeration accessories, that guarantee  the unit has high efficiency, stable performance and long service life. 

The industrial PLC control system can accurately control the energy ratio of compressor, timely and accurately control the matching between the refrigerating capacity and the cooling load, ensure the unit operates at optimal efficiency to reduce the operation cost; Internal integrated water cut, low temperature, high and low pressure antifreeze at low temperature, delay start with lack of phase, reverse phase, overload, motor overheating, oil pressure difference and many other safety protections and processing functions.

The built-in oil pressure system ensures that the compressor maintains the best lubrication effect. High-efficiency internal-threaded copper pipe enhances heat transfer effect with more energy saving and high efficiency; U-shaped heat-exchange tube bundle is convenient for maintenance and eliminates refrigerants leakage with high efficiency, low noise and small vibration. 

Non-standard models can be customized based on customers’ requirements.

 

 

 Technical Specifications: 

1. Model number specification: e.g. DC-RC50W “DC” indicates Doco company code,"RC"indicates screw chiller， "50"indicates 50 horsepower，"W"indicates water cooled chiller.
2. *Compressor power: *2indicates two compressors working and two independent refrigerating systems.
3. Refrigerating capacity parameter basis: the temperature of inlet and outlet chilled water is 12 ℃ / 7 ℃, and the temperature of inlet and outlet cooling air is 30℃ / 35℃.
4. Working ranges: the temperature range of chilling water is from 5℃ to 35℃, the temperature difference between inlet and outlet chilling water is from 3℃ to 8℃, the ambient temperature can not be higher than 40℃, and the high-temperature model should be selected when the ambient temperature is higher than 40℃.
