Heat Transfer Fluid - Low Temperature
The low temperature heat transfer fluid is engineered to offer non-toxic and low odour qualities
at an affordable price.
This fluid will satisfy the expectations of the most demanding modern day customer by
providing an environmentally sound, thermally effective heat transfer fluid with a flash point
of greater than 61°C (141°F) or greater. The fluid offers a low viscosity rating and unequalled
heat transfer characteristics through its entire operating temperature range. Recommended
temperature range -40ºC to 125ºC.
When operator safety, environmental impact and price set the benchmark for your next open
bath or closed loop heat transfer application, consider FHTFLO.
A fume hood is recommended for open baths being operated at temperatures above +50ºC
● Benefits and features
