Can the circulation pump be stopped when the temperature of the heat transfer oil furnace is at 120 degrees during shutdown?
Thread Content
I would like to ask the experts: when shutting down an electric heat transfer oil furnace, can the circulation pump be stopped when the oil temperature is at 120 degrees? Does it still have to be below 100 degrees to stop?
It’s better not to stop so early; it’s preferable to wait until the value drops below 100 before stopping, otherwise it can easily lead to carbonization of the gaskets and oil leakage
Attention must also be paid to the furnace temperature to avoid localized high temperatures caused by the cessation of circulation
