Open baths represent one of the most challenging applications for heat transfer fluids. Without careful consideration for operating temperatures and proper ventilation of the bath itself, the wrong fluid choice could prove unnecessarily costly and ultimately jeopardize workplace safety.
Oxidation is the number one cause of heat transfer fluid breakdown in open baths. It occurs when the hot fluid is exposed to the surrounding air. This unavoidable exposure to the atmosphere will result in the formation of sludge within the bath itself or gelling of the fluid. The hotter the bath’s operating temperature, the faster and more severe this reaction will be. Very few fluids will hold up under these extreme conditions for more than a few days, however, Duratherm has created this line of heat transfer fluids specifically engineered for this challenging application
