Ignix InduraMax HTF-42 HEAT TRANSFER FLUID is a high-performance heat transfer fluid formulated with severely hydrotreated, highly-refined, mineral oil base stocks. These carefully selected mineral oil base stocks create a blended product that resists oil cracking, oxidation and thickening, thus extending oil life, efficiency and circulation. Furthermore, the formulation is fortified through the use of a powerful anti-oxidant additive which severely limits corrosion as well as an additive designed to limit air entrainment.
