MultiTherm is offering the next generation of heat transfer fluid for our growing base of heat transfer fluid users. MultiTherm OG-1 is designed for use in liquid-phase heat transfer fluid systems, which are “open” to the atmosphere or there is a possibility that the heat transfer fluid in the expansion tank will come in contact with air. To reduce the oxidation process in an open-loop system, MultiTherm OG-1 is enhanced with special oxidation inhibitors to prevent this oxidative degradation and deposits. MultiTherm OG-1 heat transfer fluid is designed for a maximum film temperature of 600oF and a maximum system bulk temperature of 550oF. MultiTherm OG-1 offers the benefit of having a high flash point of 455oF / 235oC. It also offers the extra benefit of having a higher Fire Point then most other heat transfer fluids and has a Fire Point of 520oF / 271oC.
