Relatherm S-2: Premium Silicone Heat Transfer Fluid | USA Lab

Relatherm S-2 is a premium silicone-based heat transfer fluid engineered for open and non-airtight systems that demand reliable low-temperature pumpability and clean, non-fouling performance. Its high-purity silicone blend and proprietary additives provide exceptional thermal stability and a trouble-free user experience.

Unlike conventional fluids, Relatherm S-2 resists oxidation, sludge formation, and coke deposition even at elevated temperatures. The result is safer, cleaner operation with longer service intervals and reduced maintenance in open baths, circulators, and general process heating/cooling loops.

Non-toxic and non-hazardous, Relatherm S-2 supports sustainable operations and can be disposed alongside other waste oils/lubricants in accordance with applicable regulations.

For best results, operate within the recommended temperature range and follow equipment OEM guidance.
Always verify material compatibility before first use.

Maximum use temperature: 180ºC / 356°F Non-Fouling / Non-Sludging Low-Temp Pumpability Oxidation-Resistant

Extended Fluid Life: Oxidation-resistant silicone base delivers longer service life in open baths and other exposed systems.

Clean System Operation: Non-fouling formulation prevents sludge formation and carbon/coke deposits for lower maintenance.

Safer, Low-Odor Use: Designed for oxidation-free, less odorous, and cleaner performance vs. typical industry fluids.
