THE DIFFERENCE
Not only does Duratherm HF have one of the highest flash points available it also contains the industry’s most effective and resilient blend of additives to ensure long-lasting, trouble-free service. Our exclusive system includes a proprietary, dual-stage anti-oxidant and a special blend of metal deactivators, extenders, and other agents that prolong fluid life and help keep systems clean. That also means longer life for parts like pumps and rotary seals.
LASTS LONGER
Oxidation can cripple your system. Left unchecked, it will ultimately cause catastrophic failure and costly downtime. That’s why Duratherm HF offers unsurpassed levels of protection against oxidation, and a service life that other fluids simply can’t match.
RUNS CLEANER
Duratherm HF 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, including plastics processing, molding, casting, asphalt, paint, chemical and a wide variety of other applications.
ENVIRONMENTAL
Duratherm HF 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 HF 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.
