DEEPOL THERMO SERIES – High Performance Heat Transfer Oils

ISO Vis. Grades : 32, 46
DEEPOL THERMO SERIES heat transfer oils are produced from highly refined mineral base oils of intrinsic thermal and oxidation stability that is further boosted with highly effective inhibitors. They have a higher degree of heat transfer coe cient. Do not undergo thermal degradation, do not form sludge or deposits during use in the specified temperature range from -10 °C upto 320 °C. Can be used in all type of closed hot oil circulation systems used in the industry. Excellent thermal and oxidation stability assures trouble free longer operation.
• Outstanding thermal and oxidation stability, longer service periods.
• Higher heat transfer coefficient of oil increases the system eficiency.
• Superior dispersancy keeps the system clean and controls deposit formation.
• May be used in all kind of closed hot oil circulating systems used in the industry.
• Compatible with high temperature sealing elements.
