SPECIFICATION SHEET

(*) 582.22 pounds of pressure was the maximum load limit of the equipment. There was no breakdown in lubricity at this point of the Frigi-Tech sample, either before or after removal from the sealed chamber aging test.

                  Although the compression components of Centrifugal compressors require no external lubrication, rotating shaft bearings, seals and coupling must be constantly and adequately lubricated. Just as other drive systems, however, very few regular oils could meet the viscosity and dryness requirements as outlined above.

                  For reciprocal systems, the refrigerant gas carries some oil with it into the condenser and the evaporator. This oil must return to the compressor within a reasonable time period and have adequate fluidity at low temperatures. The oil must also remain miscible and be free of suspended matter that might tend to clog the system. In small, pot type, hermetic refrigeration/air conditioning system, the oil is normally never changed, so it must last for the life of the compressor.

                  In all hermetic systems, the chemical stability required of the refrigerant oil in the presence of refrigerants, metals, insulation materials and extraneous contaminants, is perhaps the most important characteristics distinguishing refrigerant oils from those used in other applications. Therefore, any product used to supplement this refrigerant oil must exhibit all of the above characteristics of refrigerant oil to the same or greater degree.

  Frigi-Tech, as shown above, not only meets these demanding standards, but also increases the oil’s lubricity.

In the field of comparison testing, we have used Suniso 3GS® as a benchmark product. Suniso is the certified refrigerant oil used as standard by numerous major manufactures of air conditioning compressors.

The viscosity before and after the addition of 5% Frigi-Tech remain the same at both test points of 100˚F and 212˚F. The viscosity index remains the same as well.

The pour point after the addition of Frigi-Tech does increase from     -45˚F to -35˚F. Although this increase does not affect most applications, including walk-in freezers, since most refrigeration units do not drop temperature below -20˚F; caution should be exercised in applications that do fall below -25˚F, and should only be attempted after conference with a qualified refrigeration engineer.

Both the flash point and the aniline point remain within the same parameters after the addition of product. The water content is increased by only 15 ppm of oil, and does not have any significant effect on the chemical stability of the oil.

The dielectric strength of the 95/5% mixture is 26,000 volts, indicating excellent insulating properties, as needed in hermetically sealed units. The Copper Strip Test shows no significant difference after the introduction of Frigi-Tech. This shows that no significant chemical reaction with copper, the common coil material, is precipitated by the introduction of Frigi-Tech.

Perhaps the only and most significant difference that was noticed after the introduction of the Frigi-Tech product was a 2,000% improvement in the mixture lubricating ability.  The modified Falex test was used to determine lubricity and the results are shown on page 1., i.e. Frigi-Tech exceeded the 582 pound limits of the test. The test is outlined in the Technical Bulletin No. 91006; the only modification was the use of a machine employing specific weights versus a torque wrench. This was done to establish a more specific “fail point”.
