Glycol to be used in coolant below 0 °C (32 °F). Freezing
not allowed.
Pressure limits Recommended default pressure: 100–150 kPa
(2)(2)
Maximum operating pressure (= Design pressure):
500 kPa
Maximum test pressure: 750 kPa
Pressure drop 50–100 kPa at rated volumetric flow
Allowed coolants Demineralized water or pure water with the quality spec-

Liquid cooling
Heat sink material Aluminum
1) Measured at a distance of 1 m (3.3 ft), the product in a reference cabinet with the doors closed.
2) The default pressure is the static state pressure without operating the cooling pump. Cooling pump operation increases the pressure typically 100–200kPa. Do not exceed the
maximum operating pressure in any situation.
