N.B. This calculation is based on the general principles of heat generation in oil-injected rotary screw compressors. As standard, heat exchangers are used to heat water from 15 °C (59 °F) to 70 °C (158 °F) (dT = 55 K) or 45 °C (113 °F) to 70 °C (158 °F) (dT = 25 K). This calculation tool is used to obtain approximate values for an initial estimate in the offer phase. To confirm technical data and heat exchanger design, e.g. for deviating temperatures, please contact your responsible KAESER expert.

Please use a decimal point as separator! (Thousands separators are not used.)
