10.2.4 Cooling Oil: Change Interval
Duty cycles and ambient conditions are important criteria for the number and length of the change
intervals.
KAESER Service will support you in determining suitable intervals and provide information on
the possibilities of oil analysis.
➤ Please observe national regulations regarding the use of cooling oil in oil-injected rotary screw
compressors.
➤ Check operating conditions and adjust intervals as necessary; log the results in table 43 for future
reference.
