When oil temperatures rise beyond acceptable levels there are a few key areas to look at in order to resolve the issue.

  • Verify the temperature reading is correct.
  • This can be done with an inline thermometer or hand held digital temperature monitor.
  • This ensures the oil temp RTD is sending the correct temperature reading to the control panel.

Thermostatic Control Valve  

  • The Thermostatic Control Valve uses a thermostat to regulate oil through the oil cooler.
  • Once the oil reaches a preset temperature range (110 or 100) the thermostat will open and allow oil to pass through the oil cooler thus maintaining a constant operating temperature.
  • If the thermostat fails, ACE  offers new replacement thermostats in 100 and 110   degree ranges.

Oil Cooler  

  • If your oil cooler isn’t performing, you may need to perform a cooler cleaning to insure there is no buildup in the water side of the tubes.

Once you have performed these basic maintenance steps, your oil systems should be ready for the added heat load of summer.
