PRO bath thermostats and circulation thermostats
The cooling output is measured when the heat transfer liquid rea-
ches a certain temperature. These temperature values are specified
in brackets. The ambient temperature for the measurement is 20 °C
and ethanol was used as a heat transfer liquid. To measure water-
cooled devices, the cooling water temperature is 15 °C and the
cooling water differential pressure is 3 bar.
The cooling water must be a minimum of 5
ambient temperature of the device to ensure efficient cooling.
Cooling water hoses
Hoses with an inner diameter of 10 mm are recommended for the
nipples supplied with the device.
