RELATHERM S-1 Silicone Heat Transfer Fluid

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*
  • 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 due to a polymerization reaction. As such, for open systems, operating temperature should not exceed the recommended 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.

COMPREHENSIVE PRODUCT PORTFOLIO

If Relatherm S-1 does not meet your application requirements, there is a very good chance that we will be able to offer a better suited solution from our comprehensive portfolio of thermal fluids and system cleaners. Contact us to discuss your application with a Thermal Fluids Expert.

Relatherm Heat Transfer Fluids offers a complete line of premium Heat Transfer Fluids and System Cleaners for all industrial applications.
