Remark:
1. The cooling capacity is calculated based on the cooling water inlet temperature of 30°C and outlet temperature of 35°C.
2. Scope of work:
Chilled water temperature range: 5℃ to 30℃; Chilled water inlet and outlet temperature difference: 3℃ to 8℃;
Cooling water temperature range: 18℃ to 30℃; cooling water inlet and outlet temperature difference: 3.5℃ to 10℃.
The working environment temperature should be ≤35℃.
The company reserves the right to change the above parameters or dimensions without prior notice.
Note: The parameters in red font above are for special parameter models. If you have special requirements, please customize them in advance.
