Quick technical note
POE 170 lubricant is a high-viscosity synthetic oil mainly used for:
-
Screw compressors
-
Industrial refrigeration systems
-
Large HVAC chillers
-
R134a / R404A / R407C / R410A systems
It is much thicker than POE 32 or POE 68, so it is normally used in heavy-duty or high-load compressors.
