Duratherm 450 Heat Transfer Fluid
Duratherm 450 is specifically engineered for applications requiring process heating and cooling efficiently between 30°F and 450°F.
Economical and thermally stable, Duratherm 450 heat transfer fluid offers an excellent alternative to costly synthetics and aromatic fluids while delivering precise and efficient cooling down to 30°F.
The Difference
Duratherm 450 heat transfer fluid contains the industries 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.
Longevity
Oxidation can cripple your system. Left unchecked, it will ultimately cause catastrophic failure and costly downtime. That's why Duratherm 450 heat transfer fluid offers unsurpassed levels of protection against oxidation, and a service life that other fluids simply can't match.
Runs Cleaner
Duratherm 450 heat transfer fluid 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.
In fact, our exclusive additive technology makes Duratherm 450 heat transfer fluid the perfect solution for all applications, large or small requiring precise temperature control up to 450° F (232°C).
Environmental
Duratherm 450 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 450 heat transfer fluid can easily be disposed of with other waste oils.
