Lack of color does make a difference
As shown by its almost water-white appearance, Paratherm HE has an extremely low level of impurities. This is the result of the extended processing required to achieve it’s HT1 Rating-approved for incidental food contact by NSF-which removes the impurities that can catalyze fluid degradation. These impurities (such as aromatics, asphaltenes and sulfur bearing compounds) give lesser quality mineral-oil based fluids a slight to moderate yellow color.
Low vapor pressure equals greater stability in vented expansion tanks
Any vapors that are given off by a heat transfer fluid inside a vented expansion tank will react with air to produce the acids that eventually can cause sludge formation and fluid gelling. The higher the vapor pressure, the more vapor is produced and the greater the rate of oxidation. Paratherm HE has a negligible vapor pressure that produces almost no reaction with air in vented expansion tanks.
