PCL SUNISO 4GS is a highly refined naphthenic mineral refrigeration oil for compressors running on CFC and HCFC refrigerants, and on the natural refrigerants PCL lists for the SUNISO GS range. It has low wax content, low pour point and high dielectric strength, which suits low-temperature systems where evaporator temperatures can fall to -42 °C.
Qishanr supplies the original PCL SUNISO 4GS, and can also assess a replacement-grade option for the same application. The grade is matched to your compressor documentation before any quotation is issued.

A highly refined naphthenic mineral refrigeration oil for systems where the compressor documentation specifies a compatible mineral oil.
PCL lists CFC and HCFC refrigerants (R-11, R-12, R-22, R-502 and others), plus the natural refrigerants R-717, R-600a and R-290. Confirm the exact requirement for your compressor before use.
Only where the OEM or qualified technical documentation confirms that mineral oil is acceptable. Most HFC and HFO systems specify POE or PAG.
The compressor or unit model, the refrigerant, the current oil grade, the pack size required and the destination port.
Yes. The 4 L pack is shown, and other formats can be arranged according to the supply route and order plan.
MOQ depends on pack size and order plan. Payment methods and trade terms are agreed with each order.
Request a product check: send your compressor model, refrigerant and current oil grade, and we will confirm the original or replacement-grade route.
