Industrial / Energy Fluids


Xceltherm® CA Plus is targeted for use in heat transfer fluid applications that require prolonged life in systems that are open to the atmosphere and subject to accelerated oxidation up to 450° F. Our advanced mineral base oils and proprietary inhibitor package enables Radco to offer a superior product for the Die Casting, Injection Molding and Extruder Markets.

Oxidative stability studies have identified the benefits of Xceltherm® CA Plus to Typical Hot Oils:
