Additional Information
WHY RELATHERM FG-1?
Relatherm FG-1 is manufactured from ultra-pure food-grade base fluids and the most advanced life-extending additive technology. In comparison with other industry fluids, it provides for a safer, cleaner, and thermally stable equipment operation. More specifically, Relatherm FG-1 features industry-leading two-stage anti-oxidation additive package and a complimentary mix of metal deactivators, rust inhibitors, defoamers, seal/gasket extenders and other proprietary agents. This superior formulation provides precise temperature control and efficient heat transfer much longer than many industry fluids.
LONGER FLUID LIFE
Relatherm FG-1 exhibits 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
By virtue of its Extended Life Additive Technology, Relatherm FG-1 greatly resists sludge formation in heat transfer systems and carbon deposition on heat transfer surfaces. It contains highly effective oxidation mitigants, making it the best choice for applications in food processing, food packaging and pharmaceutical processing. For these systems, Relatherm FG-1 may provide applicable discounts on facility insurance premiums. It also lowers maintenance costs, while offering longer uptime and less frequent fluid changeouts.
HEALTH, SAFETY & THE ENVIRONMENT
Relatherm FG-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 or disposal. After its long-service life, it can be disposed with other waste oils/lubricants in accordance with applicable statutes.
