Product Highlights

THE DIFFERENCE

Duratherm HTO’s use of highly refined base stocks ensures excellent thermal stability. Its low volatility also minimizes vapor pressure at elevated temperatures and unlike most other fluids in its class, Duratherm HTO contains antioxidants*, metal deactivators and corrosion inhibitors to further enhance the fluid’s longevity and help protect your system. *For critical applications where high levels of oxidation are prevalent please consider Duratherm 600.

ENVIRONMENTAL

Duratherm HTO is environmentally friendly, non-toxic, non-hazardous and non-reportable. Duratherm HTO poses no ill effect to worker safety.

DISPOSAL

After its long service life Duratherm HTO can easily be disposed of with other waste oils. Duratherm supports recycling and encourages oil reclamation programs where possible.

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.
