Additional Information
WHY RELATHERM O?
Relatherm O is manufactured from high purity base fluids and a potent anti-oxidation additive*. As such, it exhibits superlative thermal properties when compared to other industry fluids in its class. Its thermal stability translates into low vapor pressures, especially at high operating temperatures. The longevity of Relatherm O is well enabled by a formulation that includes metal deactivators and corrosion inhibitors.
APPLICATION
Relatherm O is an extended life thermal fluid well proven in many closed loop industrial applications. It is infused with advanced additives and a proprietary thermofluid technology that ensures clean running operation. An inert gas blanket provides the most optimal fluid life.
HEALTH, SAFETY & THE ENVIRONMENT
Relatherm O is non-toxic and non-hazardous. It is environmentally friendly and poses no adverse effect to personnel safety.
FLUID DISPOSAL
There are no special disposal procedures for Relatherm O. After its long-service life, it can be disposed of like other regular waste oils according to local, state and federal regulations. Relatherm partners with fluid recyclers and reclamation companies where applicable.
