Heat transfer fluid from -18 °C to 325 °C

CALFLOTM HTFis a heat transfer fluid based on hydrogenated mineral oils that is used in a range of -18 °C to 325 °C. The maximum permissible film temperature is 343 °C.

Application Area


In comparison to other heat transfer fluids on a mineral oil basis, CALFLOTM HTF possesses significantly higher thermal stability and has a considerable higher service life – in particular in the upper temperature range.

CALFLOTM HTF can also be used in temperature ranges in which aromatic heat transfer fluids are often used, and offers the advantage here of being odourless. In the event of thermal decomposition no toxic products such as benzene or phenol are produced.

Despite the low tendency to oxidise, it is advisable to utilize a nitrogen blanket in the expansion tank during use in high temperature ranges, in order to prevent premature agein
