The performance of an HFC system is optimized when the lubricant and refrigerant mix to form a single, clear phase (that is, they are miscible). Miscibility lowers the viscosity of the lubricant carried through the compressor. Mineral oils are not miscible with HFCs. SOLEST lubricants, on the other hand, have been specially designed to be miscible, as demonstrated in the data shown.
Excellent Thermal Stability :
Sealed tube results (ASHRAE-97) indicate that SOLEST lubricants provide excellent stability in the presence of HFC refrigerants. In addition to outstanding stability, these lubricants show no adverse effects to metals and other materials of construction.
