Paratherm Introduces AP Antioxidant Protection Additive

June 24, 2015
Paratherm AP prevents the acids that form during heating the oil from converting to sludge.

The Paratherm AP (antioxidant protection) additive is designed to be added to operating hot-oil systems to extend the oil’s useful life. Incorporating a sacrificial antioxidant, Paratherm AP prevents the acids that form during heating the oil from converting to sludge. The company notes that the AP is not a permanent cure — sacrificial additives become depleted over time and eventually the protection stops. So antioxidants don’t eliminate the need for preventive maintenance, they just reduce or delay the need for oil change-out. Periodic testing is the only truly accurate way to tell whether the additive is still present. Paratherm AP additive is available in 55-gallon drums.
