    • Description

    RELATHERM ULT Ultra-Low Temperature Heat Transfer Fluid

    Extended life thermal fluid used extensively for process cooling in chillers and other cryogenic equipment. It cools processes down to -100°C/-148°F and maintains excellent pumpability in the sub-zero temperature range. By virtue of its wide temperature bandwidth, it can also serve as a dual-use thermal fluid, eliminating the need for two different fluids where heating and cooling are required in one process.

    PRODUCT SUMMARY

    • Minimum use temperature: -100°C/-148°F
    • Maximum use temperature : 65ºC / 150°F
    • Flash Point: 49ºC / 120°F
    • Flow Assurance: Remains pumpable within specified temperature bandwidth.
    • Non-toxic and non-hazardous thermal fluid

    WHY RELATHERM ULT?

    Relatherm ULT is the result of extensive thermofluid research. It is manufactured from a blend of high purity base fluids and advanced additives that provide extreme cooling, an extended fluid life, and trouble-free operation in low-temperature applications. It features a sophisticated two-stage anti-oxidation additive package, metal deactivators, rust inhibitors, seal/gasket extenders, and other proprietary agents. These provide for a safer, cleaner, and thermally stable chiller or cryogenic equipment operation.

    EXTENDED FLUID LIFE

    Relatherm ULT 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 ULT offers extreme oxidation protection. It 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 cooling applications. For these, Relatherm ULT provides lower maintenance costs, longer uptime, and less frequent fluid changeouts.

    HEALTH, SAFETY & THE ENVIRONMENT

    In addition to being personnel friendly, Relatherm ULT is environmentally friendly and non-reportable. There are no special handling procedures for fluid disposal. After its long service life, it can be disposed of with other waste oils/lubricants in accordance with applicable statutes.
