Heat transfer Fluid - High Temperature
This high temperature fluid offers industry a practically non-toxic, versatile bath fluid that has
proven to be cost effective and thermally stable at temperatures up to +315ºC. This fluid has
demonstrated excellent performance over a wide range of temperature without compromising
economics or system integrity. Unlike the less stable mineral oil based fluid, our high temperature
fluid provides the user with the confidence and reliability without the premium price of other
fluids. Recommended temperature range +60 to +250°C.
● Benefits and features
● Low viscosity
● Improves bath uniformity and stability
● Enhanced heat-up and cool down rates
● Lower cost than glycol and silicone oil type fluids
● Safe and non-toxic
● Convenient 18 Litre (5 US gallon) containers
This fluid is not for long term (more than a few hours) continuous use above 100ºC as excessive
oxidation will occur.
As with most high temperature fluids, a fume hood is recommended for operating temperatures
above 150ºC.
This fluid should only be used with the following plastics; ABS, Epoxy, Acetal, Viton, Kalrez,
Chemraz, Fiberglass, Graphites, Fluroelastimers.
For all other plastic types contact Techne for specific recommendations.
