Mobil Thermal Heat Transfer oils are high-performance products designed for use in closed, indirect heat transfer systems. They are recommended for use in indirect heating and cooling systems that are sealed with cold oil and in all types of industrial processes. Mobil Thermal Heat Transfer Oils are developed from highly refined base oils that are resistant to thermal cracking and chemical oxidation. They have very high thermal stability and the ability to achieve an extremely long service life without formation of deposits or increase in viscosity. Mobil thermal heat transfer oils have good heat transfer capability and a viscosity that allows them to be easily pumped at both start-up and operating temperatures. The oils have specific thermal conductivity which ensures faster heat dissipation. In addition, they have flash points that are not significantly reduced during use, due to the oil's resistance to thermal cracking at the recommended operating temperatures.
