Technical Specifications:
1. Model number specification: e.g. DC-CH10A-D, “DC” indicates Doco company code, “CH” indicates constant temperature cold and hot water machine, “10” indicates 10 horsepower, “D” indicates dual system with two compressors, “T” indicates three compressors, “F” indicates four compressors.
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 40℃, 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℃.
