Cooling circuits
Cooling circuit requirements
We recommend that the cooling circuits be designed as closed systems, to prevent the
growth of algae. The maximum permissible pressure is 10 bar.
Note
We do not recommend that the cooling circuits of machines are also used to cool the motors:
We do not recommend that the cooling circuits of machines are also used to cool the motors:
Due to accumulated dirt and long-term deposits, blockage may result! This especially applies
to cooling-lubricating medium circuits.
If the cooling circuits of the machines are also used to cool the motors, then they must fulfill
all of the requirements listed here. Also note the demands on the cooling medium as well as
the maximum standstill times of cooling circuits according to the specifications of the cooling
medium manufacturer!
