Lube Oil System Options

Lube Oil Cooler

An air-to-oil type cooler is available to provide oil cooling for the gas turbine and the
driven equipment. The cooler is sized for specified heat loads and ambient temperatures
and is designed for a 22.2°C (40°F) approach temperature. The cooler is loose shipped
for offskid installation by others.

Lube Oil Immersion Tank Heater

The lube oil tank immersion heater ensures the lube oil tank temperature is adequate for
starting in cold conditions. The tank heater also facilitates a short lube oil temperature
warm up period after a cold start. Electrical supply contactors are not included.
