The oil system has a thermostatic bypass valve. When the oil temperature is less than
80 °C (176 °F) (87 °C (189 ° F) for the optional high‑water handling capacity versions),
the thermostatic bypass valve stops the oil supply from the oil cooler.
The air pressure pushes the oil from the oil separator tank through the oil filter. The oil
cooler is bypassed. When the oil temperature increases up to 80 °C (176 °F)
(87 °C (189 °F) for the optional high‑water handling capacity versions), the bypass valve
starts the supply from the oil cooler. At approximately 95 °C (203 °F) (104 °C (219 °F) for
the optional high‑water handling capacity versions), all the oil flows through the oil
cooler. The filtered oil flows into the pump element.
Cooling
The cooling system has an oil cooler. The fan blows air over the coolers. The fan is set to
on or off, depending on the operating conditions, as per the specific algorithm.
2.4 Condensate system
When discharge pipes are used, water in the discharge air can condense in the pipes.
This water is collected in the collector of the outlet pipe where a drain point is available.
Initially, the drain point is connected to the external valve. Prevent condensate collection
in the oil separator to extend the oil life. Refer local regulations which are applicable for
water drainage.
