Cooling water quality
The values specified for the cooling water correspond to the requirements for a closed cooling circuit.
Not all of the specified concentrations will occur in the cooling water at the same time.
A filter can be installed to ensure fault-free operation. The filter fineness should be no less than 100 μm.
