Summit PG-E Series are full synthetic lubricants formulated for oil flooded rotary screw compressors in hydrocarbon gas applications. It is designed to reduce the degree of viscosity dilution experienced by mineral oils and most other synthetics. It is for high BTU hydrocarbon gases where crude oil is allowed to enter the compressor intake and contaminate the compressor lubricant.
PG-E Series lubricants have a high degree of solvency, which keeps the crude oil contamination in solution. This results in longer lubricant life and longer filter life. Crude oil is not soluble in most PAG based lubricants normally used in this type of service. This limited solubility results in frequent plugging of oil filters and coalescing elements leading to high filter costs and manpower requirements. Use of PG-E Series may also result in longer life for mechanical seals by keeping the seal faces free from deposits for an extended time. Since crude oil consists of various compounds, the degree of crude oil solubility in PG-E Series may vary among different locations.
It is recommended PG-E Series not be mixed with mineral, PAO or other hydrocarbon based oils since this will limit its ability to absorb crude oil and may exceed the compatibility limits of the lubricant.
