POE selection for HFC systems
For buyers comparing wholesale refrigeration oil and wholesale poe refrigeration oil, QSL-170H gives a clear POE path for HFC compressors that need a stable viscosity profile, retrofit support and a direct route to quote.
HFC compatibility
QSL-170H is positioned for industrial refrigeration and HVAC work where the buying decision starts with system fit, then moves to viscosity and service stage.
| Refrigerant family | HFC refrigerants such as R134a, R404A and R407C are named on the product page. |
|---|---|
| Compressor types | Screw, scroll and centrifugal compressors are all listed as target equipment. |
| Service stage | Initial system fill, aftermarket service fill and retrofit work are all described uses. |
| Buying note | If the system uses another refrigerant family or a different compressor spec, confirm the nameplate and oil reference before ordering. |
Viscosity and stability
The product page gives enough hard data to help a buyer compare grades without guessing. These are the values worth keeping in front of the compressor spec sheet.
The goal is not to pile up specs. It is to tell a buyer whether the oil keeps its shape across operating temperature, supports film strength, and fits the service profile of the system.
Service-fill checklist
This section turns the retrofit and service-fill language on the product page into a practical buyer checklist.

The page identifies HFC refrigerants such as R134a, R404A and R407C. If your system uses another refrigerant family, confirm the compressor documentation before selecting oil.
Screw, scroll and centrifugal compressors are named on the product page, so those are the first systems to match against.
170 cSt at 40°C and 17 cSt at 100°C, with VI 107, point to a high-viscosity synthetic oil suited to HFC service needs.
Yes. The product page describes initial system fill, aftermarket service fill and retrofit use.
