DETAIL
Contaminated or blocked coolers
If oil or outlet temperatures rise at a comparable load, contaminated radiator surfaces, added airways or a faulty fan can limit the heat dissipation.

Oil & cooling water temperature
Temperature trends show whether cooling and lubrication are stable before limit shutdowns or accelerated wear occur.

Why monitor?
What this parameter reveals about your compressed air station.
Temperatures respond early to changes in heat dissipation, friction and operating conditions. Together with load, ambient temperature and running time, they help distinguish a brief peak from gradual deterioration.
DETAIL
Problems in the cooling water cycle
Unusual feed and return temperatures indicate too low a volume flow, deposits in the heat exchanger, valve faults or a disturbed pump.
DETAIL
Assessment of lubrication and load
Slowly rising oil temperatures may indicate changes in oil quality, increased friction or permanently unfavorable operating conditions.
In practice
The oil cooling circuit of a compressor.
The temperature at the airend outlet shows the thermal load where the compressed air and oil mixture is hottest.
Legend: a = airend; b = oil separator; c = compressed air and oil outlet, the hottest point of the compressor. Original diagram with German labels.
