WHY RELATHERM S-LT?
Relatherm S-LT boasts of one of the lowest operating temperatures of any thermal fluid in the industry. It is manufactured from a blend of high purity base fluids and proprietary additives that ensure fluidity and that sludge formation and coke deposition do not occur. Relatherm S-LT 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, especially in open systems.
EXTENDED FLUID LIFE
Relatherm S-LT 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-LT has a service life much longer than most thermal fluids in exposed systems.
NO OXIDATION! NO GUNK!!
Relatherm S-LT 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-LT provides lower maintenance costs, longer uptime and less frequent fluid changeouts.
HEALTH, SAFETY & THE ENVIRONMENT
Relatherm S-LT is an environmentally friendly fluid. It contains no PolyFluoroAlkyl Substances (PFAS) .
