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.

COMPREHENSIVE PRODUCT PORTFOLIO

If Relatherm O does not meet your application requirements, there is a very good chance that we will be able to offer a better suited solution from our complete portfolio of thermal fluids and system cleaners. Contact us to discuss your application with a Thermal Fluids Expert.
