Duratherm 630
- "Duratherm is the best heat transfer fluid we've ever used." — Larry Daniels
- "This stuff is pretty amazing." — Ryan Seward
- "These products performed exceptionally well for us." — S. Poletto
- "I commend you on the quality and longevity of your products." — H. Blair
- "Duratherm saves money in the long run." — J. Smith
Duratherm 630 is a high performance, efficient and environmentally friendly fluid engineered for applications requiring high temperature stability to 630°F. Offering precise temperature control it’s a great alternative to high temperature aromatic fluids, at a fraction of the cost.
It is ideal for a wide range of applications including, high temperature batch processing, chemical reactions, pharmaceutical and resin manufacturing among others.
The Difference
Our exclusive additive package, including a proprietary dual stage anti-oxidant, ensures long trouble free operation. Duratherm also incorporates metal deactivators, a seal and gasket extender, defoaming and particle suspension agents.
Lasts Longer
In the heat transfer fluid industry cost is always a concern, however fluid longevity and resistance to harmful fouling are of equal importance.
Air contact is normally detrimental to a fluid. Oxidation can cripple your system and if left unchecked will ultimately cause catastrophic failure. Unscheduled downtime due to oil failure has a high cost and negative effect on production.
The Duratherm product line was developed with this in mind. Most other fluids fall short in their protection from oxidation and can quickly foul a system. Duratherm is engineered to give unsurpassed levels of protection and service life.
Runs Cleaner
In our effort to truly service the heat transfer industry, we have developed unique and specific heat transfer system cleaners. Ranging from preventative maintenance system cleaners to emergency downtime system revivers, we have a cleaner that fits your needs and schedule.
Environmental
Duratherm 630 is environmentally friendly, non-toxic, non-hazardous and non-reportable. Worker health and safety is of great concern, Duratherm 630 poses no ill effect to worker safety. After its long service life it can easily be disposed of with other waste oils.
