Emulsion with corrosion protection Corrosion protection oils for coolant circuits contain emulsifiers which ensure
a fine distribution of the oil in the water. The oily components of the emulsion
protect the metal surfaces of the coolant ducts against corrosion and cavita‐
tion. Here, an oil content of 0.5 to 2 volume percent has proved successful.
If the corrosion protection oil is intended to lubricate the coolant pump in ad‐
dition to providing corrosion protection, the required oil content is approx. 5
volume percent.
Comply with instructions of the pump manufacturer!
Cleaning the coolant circuit Inspect and clean (purge) the cooling system at regular intervals as specified
in the machine and cooling system manufacturer's maintenance schedule.
Note that the utilization of unsuitable cleaning agents may cause irreversible
damage to the motor cooling system. This type of damage does not lie within
the responsibility of Bosch Rexroth.
Risk of damage to the motor cooling system
by improper cleaning agents! Loss of warran‐
ty!
CAUTION
● The only liquids or materials allowed for cleaning and motor cooling are
liquids which do not corrode the motor cooling system and do not react
aggressively to the materials used in Bosch Rexroth motors.
● Refer to the instructions of the manufacturers of the cleaning agent and
the cooling system.
