FREQUENTLY QUESTIONS & ANSWERS
WILL THE OIL SETTLE OUT?
No. AircoFridge Optimizer contains NO solids. The Components cannot settle out, or be filtered out. They are actually chemically bonded to the napthenic oil base molecules.
IS AFO COMPATIBLE WITH ALL REFRIGERATION OILS?
AFO is compatible and will readily mix with standard refrigeration oils because both AFO and standard refrigeration oils are napthenic based. AFO is compatible and will mix readily with some synthetic oils. Contact your AFO representative to determine the compatibility of any synthetic oil applications you may have.
IS AFO COMPATIBLE WITH ALL REFRIGERANTS?
AFO oil is readily miscible in the following refrigerants:
R-744 Carbon Dioxide
R-40 Methyl Chloride
R-764 Sulfur Dioxide
There is a tremendous effort in developing environmentally safe refrigerants. As the products come to market, AFO will perform tests to determine product compatibility, and will modify the formulation to meet new requirements as needed.
WILL THE PROTECTIVE FILM AFFECT BEARING TOLERANCES?
No. The contact activated barrier that bonds to all metal surfaces is extremely thin. The thickness of this film cannot be measured by the tools available to a machinist. The presence of this film will not affect bearing tolerances of their alignment.
DOES THE COMPONENT IMPROVE MECHANICAL SEAL LIFE?
Yes. Semi-hermetic units require mechanical shaft seals to retain the valuable refrigerant charge, and to keep out air and moisture. Mechanical seals utilize two ultra-precision machined and polished surfaces to generate a zero leakage shaft seal. The mechanical seal is, by far, the most precisely manufactured and most delicate component in the compressor. The seal’s highly polished surfaces can easily be damaged by dry starts, corrosion, or rough bearings. Since these problems are avoided or at least minimize in units treated with FRIGI-TECH, the mechanical seal life is improved.
DOES THE COMPONENT AFFECT ELECTRIC MOTORS?
Motors in hermetically sealed units will enjoy similar benefits that compressors receive. 70% of all hermetically sealed motor failures are caused by bearing failures. Although it may appear on the surface that the motor failure is electrical in nature, in most cases it is a bearing failure that causes a motor stator misalignment which, in turn, causes motor winding damage. Since motor bearings receive the same protection as compressor bearings, motor life is extended when AFO is used.
WHAT TEMPERATURE RANGES CAN AFO BE USED?
This product can be used where temperatures are as low as -65F, or as high as 400F.
