CPI Refrigeration Oil is a special lubricant for refrigeration compressors, also known as refrigeration oil, produced by CPI in the U.S.A. CPI Refrigeration Oil is mainly used in refrigeration compressors with R22, R12 and R502 as the working fluid, and has good lubrication, especially at low temperatures, because it has good compatibility.
تفاصيل القضية
The characteristics of CPI refrigeration oil are as follows:
Chemical stability: CPI Refrigeration Oil has superior chemical stability and is resistant to the effects of metals and refrigerants in the system.
Lubricity: CPI Refrigeration Oil is refined from selected naphthenic crude oils using a special process that ensures excellent lubricity.
Cleanliness: The use of CPI Refrigeration Oil reduces valve deposits, reduces the likelihood of downtime and keeps the compressor clean.
Low temperature performance: CPI refrigeration oil has good solubility of R22 and R502 to enhance low temperature performance.
Oil return: CPI-4700 series refrigeration oils have good oil return and are suitable for use in refrigeration compressors with R22, R12 and R502 as the working fluid.
Thermal stability: CPI-4700 series refrigeration oils have good thermal and oxidative stability, and are suitable for refrigerators and air-conditioning refrigeration equipment with Freon as refrigerant.
System efficiency: CPI-4700 series refrigeration oils can improve system efficiency, have a low tendency to generate foam, have a low flocculation point and outstanding compatibility.
Main Series of CPI Refrigeration Oil
1.CPI-1507 Series
CPI-1507-68
CPI-1507-68 is formulated by using premium polyalkylene glycol (PAG), coupled with a high performance additive package. The lubricant is specifically formulated to give negligible solubility or dilution in hydrocarbon gases.
Characteristics
CPI-1507-68 features excellent thermal and oxidation stability that enables operation over a wide range of temperatures without degradation, varnish, deposit formation, or corrosion.
The low volatility of the product provides reduced maintenance and reduced top-ups, and the excellent lubricity will provide increased efficiency and reduced cost of operation.
Application areas
The product can be used for flooded rotary screw compressors, centrifugal compressors and liquid ring vacuum pumps.

2.CP-4600 Series
CPI-4600-100
Product description
CPI-4600-100 is a custom-blended polyalphaolefin (PAO) synthetic oil with superior stability.
Application areas
CPI-4600-100 is a long life lubricant formulated especially for flooded screw compressors.
Characteristics and advantages
CPI-4600-100 provides improved lubrication at high and low temperatures, reduced volatility, good chemical
inertness and hydrolytic stability, and compatibility with mineral oils and equipment designed for use with mineral oils.
A low pour point prevents the lubricant from congealing in refrigeration lines.
