Qishanr supplies PCL SUNISO 4GS, a highly refined mineral refrigeration lubricant for refrigeration and air-conditioning compressors using the refrigerants specified by the equipment and lubricant documentation. We can arrange the original PCL SUNISO product and can also assess a replacement-grade option when the compressor model, refrigerant and current oil are provided.
The current PCL SUNISO GS reference data lists 4GS at 55 cSt at 40 °C, 5.9 cSt at 100 °C, density 0.916 kg/L at 15 °C, flash point 184 °C, pour point -42 °C, floc point -54 °C and dielectric strength 40 kV. These are typical production values, not a product specification.
| Property | 4GS typical value | Method |
|---|---|---|
| Density @ 15 °C | 0.916 kg/L | ASTM D4052 |
| Viscosity @ 40 °C | 55 cSt | ASTM D445 |
| Viscosity @ 100 °C | 5.9 cSt | ASTM D445 |
| Flash point | 184 °C / 364 °F | ASTM D92 |
| Pour point | -42 °C / -44 °F | ASTM D97 |
| Floc point | -54 °C / -66 °F | ASHRAE 86 |
| Dielectric strength | 40 kV | ASTM D877 |
The SUNISO GS range is used in consumer and commercial refrigeration and air-conditioning systems. The application scene below shows a cold-room compressor unit; it is an application reference image, not a SUNISO product photograph. Confirm the compressor type, refrigerant and oil requirement before filling or changing lubricant.

PCL publishes the SUNISO GS range for CFC and HCFC refrigerants and also lists natural refrigerants including ammonia (R-717), isobutane (R-600a) and propane (R-290). Use only where the compressor manufacturer or system documentation specifies a compatible mineral refrigeration lubricant. SUNISO GS is not a universal substitute for POE or PAG oil in HFC/HFO systems.
The supplied product image shows a 4 L pack. Other pack sizes may be arranged subject to the selected supply route and stock plan. MOQ varies by pack size and order plan. We can discuss T/T, L/C and other payment methods, together with EXW, FOB, CFR, CIF and other trade terms according to shipment requirements.
Guangzhou Qishanr Technologies Co., Ltd. supplies refrigeration lubricants from Foshan, Guangdong, China. We support product selection, original-product sourcing, replacement-grade assessment, export documentation and OEM/ODM packaging services. For replacement assessment, send the compressor or unit model, refrigerant, current oil grade and required pack size.
We can provide product documentation for the selected supply route. Send your compressor model, refrigerant, application, pack size and destination port so we can confirm the suitable route and quotation.
Request a product check: send the compressor model, refrigerant and current oil grade for an original-product or replacement-grade assessment.
