Mineral Oil Heat Transfer Oils are high performance products intended for use in closed indirect heating installations. Mineral Oil Heat Transfer Oils are formulated from highly refined base stocks that are resistant to thermal cracking and chemical oxidation. Mineral Oil Heat Transfer Oils have good heat transfer efficiency and their viscosities are such that they can be pumped readily at both start-up and operating temperatures. The flash points of these oils will not decrease significantly in service because of their resistance to thermal cracking at the operating temperatures for which they are recommended. The products are very thermally stable and are capable of an extremely long service life without deposit formation or viscosity increase. Mineral Oil Heat Transfer Oils demonstrate specific heats and thermal conductivities that provide more rapid heat dissipation. Mineral Oil Heat Transfer Oils are recommended for use in both closed and open, cold-oil sealed, indirect heating and cooling systems in all kinds of industrial processes
