13.4 Cooling output
Measuring the performance data according to DIN 12876
The cooling capacity is measured at fixed temperatures of the heat
transfer liquid. Ethanol is used as the standard heat transfer liquid,
thermal oil is used for temperatures above 20 °C. The ambient
temperature for the measurement of air-cooled devices is 20 °C.
For the measurement of water-cooled devices the cooling water
temperature is 15 °C as well as the cooling water differential pres-
sure 3 bar.
All water-cooled devices are equipped with the following cooling water con-
nection:
