POE Oil Manufacturer,Supplier and Exporter in India
Product Code : EL-MWLE-13062
Jlab Export is a leading POE Oil Manufacturer,and suppliers in India
POE (polyolester) oil is the synthetic compressor lubricant used with HFC refrigerants such as R-134a, R-404A and R-410A, which do not mix with mineral oil. This POE oil comes in two viscosity grades, 3GS and 4GS. Like every polyolester oil it takes up moisture from the air quickly, so the container stays sealed until the moment of filling.

Compressor Oil Practicals on HFC Systems
Trainees learn oil handling when they replace a compressor on an HFC training circuit. They drain and measure the oil from the old compressor, add fresh POE to match and braze the new unit in. The circuit is then pulled down with one of the Small Vacuum Pumps, because moisture left inside reacts with POE to form acid.
Charging practice follows, with R-410A Refrigerant weighed into the system. After a compressor burnout exercise, students draw an oil sample and test it with the Acid Test Kit For All Refrigeration Oils. Its colour change shows whether acid has formed.
Frequently Asked Questions
Which refrigerants need POE oil?
POE is the usual compressor oil for HFC refrigerants, including R-134a, R-404A and R-410A in stationary refrigeration and air conditioning. These refrigerants do not mix with mineral oil, which would collect in the evaporator instead of returning to the compressor.
What is the difference between the 3GS and 4GS grades?
They are two viscosity grades, named after the grades used for mineral refrigeration oil. 4GS is the thicker oil and 3GS the thinner one. Fill with the grade the compressor maker gives on its label or service sheet.
Why must the container be kept closed?
POE is strongly hygroscopic. It draws water from the air soon after opening, and wet oil breaks down into acids that attack motor windings and valves. Open the container only to fill, close it at once and use the oil up soon.
Can POE be mixed with mineral oil?
POE tolerates a small amount of leftover mineral oil, which is why it is used when an older system is converted to an HFC refrigerant. In a system built for HFCs from the start, use POE alone.
