At what temperature will the Lube Oil settling tank heater automatically de-energize?

Explanation:
The heater uses a high-limit temperature control that shuts power off when the oil reaches a set maximum. For this system, that maximum is 450°F, so once the oil hits 450°F the thermostat opens and the heater de-energizes. It will re-energize only after the oil cools enough for the thermostat to reset, maintaining safe operation and protecting the oil from overheating. Other temps shown would not represent the designed high-limit point; they wouldn’t capture the automatic cutout behavior at the intended safety threshold.
