Additional Information
WHY RELATHERM HT-2?
Relatherm HT-2 is a well proven heat transfer fluid formulated from a superior blend of high purity base fluids and advanced additives. These include a proprietary two-stage anti-oxidation additive package, metal deactivators, rust inhibitors, seal/gasket extenders and other proprietary agents. Therefore, in comparison with other industry fluids, Relatherm HT-2 provides for a safer, cleaner, and thermally stable equipment operation.
EXTENDED FLUID LIFE
Relatherm HT-2 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
Relatherm HT-2 greatly minimizes sludge formation in heat transfer systems and the fouling of heat transfer surfaces by virtue of its robust additive technology. It contains highly effective oxidation mitigants, making it the best choice in many industrial applications such as plastic processing equipment, chemical reactors, solar power plants, die casting machines and many more.
For these systems, Relatherm HT-2 provides lower maintenance costs, longer uptime and less frequent fluid changeouts.
HEALTH, SAFETY & THE ENVIRONMENT
Relatherm HT-2 is non-toxic and non-hazardous. It is environmentally friendly and poses no adverse effect to personnel safety.
