Harbin Boiler Fuel reminds you that generally speaking, the actual higher operating temperature of any heat transfer oil product, especially mineral oil-based products, should be at least 10℃ lower than its higher allowable operating temperature to ensure a certain service life and better safety and economy.

To prevent over-oxidation, as thermal oil is prone to oxidation reactions at high temperatures in heat carriers, leading to deterioration, nitrogen protection should be applied to the high-temperature expansion tank to ensure the system's sealed integrity and avoid contact with air, thereby extending the service life of the thermal oil.
