Heat Transfer Fluid
Our fluids outlast all others
... even ones costing many times more!
Our exclusive additive system delivers unparalleled protection and service life. This report shows Duratherm's superior resistance to oxidation, the main cause of sludge buildup and fluid degradation.
"We used to use Paratherm but it had a tendency to sludge up. Duratherm does not sludge up at all." — Bill Corbett, Computer Plastic Inc.
"The difference was amazing. After an entire year of running Duratherm 600 the sludge buildup was minimal compared to Calflo after only 6 months." — J. Gerbec, Cantex Inc.
"We have been using Duratherm 600 and Duratherm G since 2003. Since then our oxidation problems have disappeared." — H. Blair, Saint-Gobain Crystals and Detectors
"Since we changed over to Duratherm, I've had zero pump and valve failures. The heat exchangers aren't clogging as they did with Calflo." — R. Barnett, Nursery Supplies Inc.
"The difference is clear – literally! We have had one of the baths in use for approximately 3 months and the fluid is still clean and clear." — S. Bailey Sr., Parker Hannifin Corporation
About the Test
We chose 6 competing products, ranging from low budget hot oils to some of the more expensive premium fluids from Exxon Mobil Corporation®, Dow Chemical Company®, Paratherm Corporation®, Petro-Canada Inc®, Momar® and Multitherm LLC®.
About the Method
IP48 is an International Petroleum test standard in which 40ml of fluid is exposed to 400°F with 15L/h of air blown through the samples for 24 hours. This accelerates a fluid's aging process and shows a fluid's resistance to oxidation.
