    Heat transfer Fluid for 300F Process

    Hello,

    I am looking for a heat transfer fluid for a process. My bulk temp will be a max of 300F (obviously a bit higher at the interface with my furnace.) This is a closed system, but I can't go over 25 PSI. Will be in contact with carbon steel, stainless steel, and copper. A food grade or at least non-toxic option would be optimal.

    10 months out of the year we will be running between 140F and 180F. 2 months out of the year we will run at 300F. I would like a fluid that will last for years with minimal (or zero) maintenance.

    I am considering 100% triethylene glycol for a heat transfer fluid, or an aliphatic hydrocarbon based fluid.

    What would you advise that I use?

    Thanks for your help!

    Have you looked at Paratherm, it is a food grade synthetic oil and can meet/exceed your high temperature requirement.

    So you're recommending an oil based transfer fluid. Stable (especially as I won't be even close to the high temp range for the fluid.) Will work great for long-term service.

    Thank you for your input, I will contact them and get a quote.
