Non-Fouling Heat Transfer Fluid is capable of operating system under a temperature ranging up to 55 degree F or 290 degree C. The Heat Transfer Fluid is a synthetic fluid that can resist the effects of oxidation 10 times better than mineral oils. The Heat Transfer Fluid exhibits less oxidation means less solids formation and much less fouling. The Non-Fouling Heat Transfer Fluid is pumpable at -15 degree F and allows the system to start-up quickly and easily.
