WHY RELATHERM HT-3?

Every drop of Relatherm HT-3 contains the most advanced, industry-leading additive technology. In comparison with other industry fluids, it provides for a safer, cleaner, and thermally stable equipment operation. Relatherm HT-3 features a proprietary two-stage anti-oxidation additive package and a complimentary mix of metal deactivators, rust inhibitors, seal/gasket extenders and other proprietary agents. This superior formulation provides precise temperature control and efficient heat transfer much  longer than its contemporaries.

LONGER FLUID LIFE

Relatherm HT-3 is well known for it extended service life, even in oxidation-prone systems. Its superior additive technology extends its usability under operating conditions at which other industry fluids would typically degrade.

MAXIMUM OXIDATION PROTECTION

By virtue of its robust additive technology, Relatherm HT-3 greatly minimizes sludge formation in heat transfer systems and carbon deposition on heat transfer surfaces. It contains highly effective oxidation mitigants, making it the best choice in many industrial applications. For these systems, Relatherm HT-3 provides lower maintenance costs, longer uptime and less frequent fluid changeouts.

HEALTH, SAFETY & THE ENVIRONMENT

Relatherm HT-3 is non-toxic and non-hazardous. It is environmentally friendly and poses no adverse effect to personnel safety. There are no special handling procedures for fluid disposal, it can be disposed with other waste oils/lubricants in accordance with applicable statutes.
