The coolant must have a similar thermal capacity to water (specific thermal capacity at 20 °C
c=4.18 kJ/kgK). Industrial water without any air bubbles or sediments is recommended as a coolant.
The hardness of the water must be between 1 dH and 15 dH; the pH value must be between pH 7.4
and pH 9.5. No aggressive liquids may be added to the coolant!
The coolant pressure must not exceed 8 bar. The required quantity of coolant is 10 litres/minute,
and the coolant inlet temperature must not exceed 40 °C; we recommend 10 °C.
We also recommend fitting a pressure reducer or similar at the coolant inlet to avoid damage due to
excessive pressure.
If there is a danger of frost the operator should add a suitable anti-freeze solution to the cooling water.
The temperature of the cooling water and the cooling water flow rate must be supervised and
ensured by the operator. The drive must be shut down if the permissible temperature is exceeded.

4.4 Running-in time for the worm gear unit
In order to achieve maximum efficiency of the worm gear unit, the gear unit must be subjected to a
running-in period of approx. 25 h – 48 h under maximum load.
