Figure 3-7 Secondary section cooling consisting of heatsink profiles with hose connector nipples
and cover end pieces on both sides for all motors of sizes 1FN3050 … 1FN3450 (side
and top view)
Note
Pressure drop for combi adapter and end piece
Because of the high pressure drops, only use secondary section cooling with a combi
adapter / combi end piece for traversing distances up to a length of approx. 2
m. Check the
pressure drop as part of the design of the entire cooling system.
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.
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.
