Cooling circuits

Cooling circuit requirements
Avoid algae growth by using suitable chemical agents and opaque water hoses.
We recommend that the cooling circuits be designed as closed systems. The maximum
permissible pressure is 10 bar.
NOTICE
Blocked and clogged cooling circuits
Cooling circuits can become blocked and clogged as a result of pollution and longer-term
deposits.
• We recommend that you use a separate cooling circuit to cool the motors.
● If you use the machine cooling circuits to also cool the motors, you must ensure that the
coolant fully complies with the requirements listed in this chapter.
● Also note the maximum non-operational times of cooling circuits corresponding to the
coolant manufacturer's data.
