LUBRIPLATE HTO SPECIAL is highly refined mineral-oil based heat transfer fluid designed for use up to 600F(316C) in closed-loop systems. LUBRIPLATE HTO Special’s low pour point provides easy start up in cold environments. Lubriplate HTO Special is also formulated with oxidation inhibitors, corrosion inhibitors and metal deactivators not found in most heat transfer fluids of this type; resulting in much longer oil life. This is demonstrated in this ASTM D2440 test run by an independent laboratory.
