High-temperature heat transfer oil

High-temperature heat transfer oil is produced from refined base oils, high-temperature antioxidants, and anti-coking additives. It provides thermal stability, oxidation resistance, low-temperature fluidity, and efficient thermal conductivity for industrial liquid-phase heat transfer systems.

The product is suitable for oil heaters, oil baths, drying chambers, heat-setting machines, reactors, distillation equipment, and rectification systems. Under no-air-access operating conditions, the appropriate grades are rated for maximum operating temperatures of 280°C, 300°C, and 320°C.

Ningbo MOS Chemical Co., Ltd. manages international B2B sales and export deliveries for MOSINTER GROUP. Through the group-invested manufacturing network, we support industrial users, lubricant distributors, importers, and private label customers, providing bulk supply, large wholesale orders, and OEM cooperation.
