No oxidation! No gunk!! This engineered thermal fluid is formulated for absolute resistance to fluid degradation. In a class of its own, it boasts of premium performance, extended life, and extreme stability in a variety of demanding applications.
PRODUCT SUMMARY
- Oxidation-proof thermal fluid great for open baths and other aerated systems
- Maximum use temperature: 315ºC / 600°F in closed systems and 204ºC / 400°F* in open systems.
- Great chiller/cooling fluid down to -51°C (-60°F)
- Non-toxic and non-hazardous thermal fluid
*In open systems operating above 204ºC / 400°F, gel formation is known to occur rapidly due to a polymerization reaction. As such, for open systems, the operating temperature should not exceed the recommended maximum use temperature.

WHY RELATHERM S-1?
Relatherm S-1 is the result of extensive thermofluid research into effective non-fouling options for open systems. It is manufactured from a blend of high purity Silicone fluids and proprietary additives that ensure that sludge formation and coke deposition do not occur. Relatherm S-1 is thermally stable, even at elevated temperatures. In comparison with other industry fluids, it provides for an oxidation-free, less odorous, safer, cleaner, and trouble-free operation.
EXTENDED FLUID LIFE
Relatherm S-1 is often selected for its durability and oxidative-stability in typically problematic systems such as open baths. Its base chemistry is non-susceptible to oxidation. As such, Relatherm S-1 has a service life much longer than most thermal fluids in exposed systems.
NO OXIDATION! NO GUNK!!
Relatherm S-1 is fully resistant to oxidation in open and non-airtight systems. By virtue of its uniquely stable chemistry, it is non-susceptible to oxidative reaction mechanisms. This translates into the absence of sludge and carbon deposits. When used within the specified operating range, Relatherm S-1 provides lower maintenance costs, longer uptime and less frequent fluid changeouts.
Relatherm S-1 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. After its long-service life, it can be disposed with other waste oils/lubricants in accordance with applicable statutes.
