HTFs: Is the product food safe / food grade?

Heat transfer fluids are frequently used to lower temperatures in storage areas, manufacturing processes and the processing of food and drink. For consumer safety, it is necessary to select a non-toxic heat transfer fluid.

There is no such thing as a “food grade” heat transfer fluid, or even one of “food-grade quality”.

A heat transfer fluid is not a food-grade ingredient. There are however heat transfer fluids registered by the National Sanitation Foundation (NSF) for accidental contact with foods such as Greenway Neo N, a bio-sourced HTF from Climalife.


NB: in the event of contact with a heat transfer fluid, the contaminated food product must not be placed on the market.

NSF HT1 registration does not imply that the contaminated food product can be consumed.
