Duratherm S Heat Transfer Fluid
Duratherm S is ideal for applications such as negative pressure mold heaters, annealing tanks, open bath forming, or any processing equipment where oxidation is prevalent and problematic. Duratherm S resists the effects of oxidation seen with most other heat transfer fluids.
High temperature stability is maintained to 650°F.This combined with a low end working temperature of -40°F also makes Duratherm S ideally suited for low temperature applications, batch processing or any application requiring a single fluid for both heating and cooling.
Duratherm S is an extremely oxidative and thermally stable heat tranfer fluid offering precise temperature control in applications requiring the highest level of oxidative stability with high and low termperature workability.
The Difference
- Superior oxidation resistance∗ (virtually unaffected)
- Non-fouling - extremely long life
- Low odor
- Non corrosive
- Non hazardous
- Non Toxic
- Extremely high working temperature (650°F)
- Extremely low working temperature (-40°F)
Lasts Longer
Duratherm S is a high performance, extremely stable, long lasting silicone based heat transfer fluid.
Virtually unaffected by oxidation∗ Duratherm S is perfect for use in a variety of applications requiring a safe, non reportable, non-toxic and non corrosive heat transfer fluid.

"The heat transfer appears to be the best it's ever been " — R. Barnett
"You manufacture products that perform exactly as advertised, which is not always the case in the marketplace." — H. Blair
"We were thoroughly impressed with DuraClean Ultra. The system was spotless, and all of the hard build-up was completely removed in only 6 hours" — M. Fransiscovich
"You proved once again that while your goal is to grow. It's through honest customer service and great products." — K. Rose
"The oil still looks as clear as it did when we first put it into use." — J. Thomas
"We used to have to roto-rooter the heater zones due to clogging. This hasn't been a problem since we switched to Duratherm 600." — R. Barnett
