THE DIFFERENCE
Our exclusive additive package, including a proprietary dual stage anti-oxidant, ensures long trouble free operation. Duratherm 630 also incorporates metal deactivators, a seal and gasket extender, de-foaming and particle suspension agents.
LASTS LONGER
Oxidation can cripple your system. Left unchecked, it will ultimately cause catastrophic failure and costly downtime. That’s why Duratherm 630 offers unsurpassed levels of protection against oxidation, and a service life that other fluids simply can’t match.
RUNS CLEANER
Duratherm 630 delivers superior resistance to sludging, a problem plaguing most other fluids. That makes it the best defense against extreme oxidation found in many of today’s demanding manufacturing environments.
ENVIRONMENTAL
Duratherm 630 is environmentally friendly, non-toxic, non-hazardous and non-reportable. It poses no ill effect to worker safety and does not require special handling. After its long service life, Duratherm 630 can easily be disposed of with other waste oils.
SYSTEM CLEANING
If your existing fluid has let you down and left you with a system full of sludge or carbon, we’ve developed a full line of heat transfer system cleaners to get your system back to like-new condition.
