Note:1Nominal cooling capacity is according to:inlet chilled fluid temperature:12°C;outlet chilled fluid temperature:7°C;inlet cooling air temperature:30°C;outlet cooling air temperature:35°C.
Working range:The temperature range of chilled fluid is from 5°C. To 35°C.Temperature difference between inlet and outlet chilled fluid is from 3°Cto 8°C.
It is better to use the chiller while the ambient temperature at or below 35°C
