Both versions of the liquid-cooled drive units, with integrated and external
heat exchanger, are supplied filled with liquid. The coolant comprises tap
water and antifreeze, type Antifrogen N (Clariant). It is mixed in the ratio 1
: 1. This guarantees frost protection down to -30 °C.
CAUTION
Antifreeze is hazardous to health!
⇒
If antifreeze is swallowed, immediately consult a
doctor and keep the packaging or label for reference.
CAUTION
Mixture with other antifreezes!
⇒
Do not mix the coolant with other antifreezes.
⇒
Only use the specified antifreeze if coolant must be
added to installed drive units.
WARNING
Burns due to hot components with
temperatures above 30 °C!
⇒
Wear protective gloves
⇒
Replace devices only when the liquid circulation
system has cooled
