Mineral Oil Manufacturer,Supplier and Exporter in India
Product Code : EL-MWLE-13064
Jlab Export is a leading Mineral Oil Manufacturer,and suppliers in India
Mineral refrigeration oil lubricates compressors in older CFC and HCFC systems, such as those built for R-12 and R-22. Many hydrocarbon systems running on R-600a or R-290 use it as well. This oil comes in the 3GS and 4GS viscosity grades. It takes up less moisture than POE or PAG, but a container left open still lets damp air spoil it.

Refrigeration Lab Exercises with Mineral Oil
Students work on a domestic refrigerator circuit that runs on R-600a. They drain the oil from a replaced compressor, measure how much it held and compare its colour with fresh oil. The circuit is then evacuated and charged with R-600a Refrigerant, with the pressures read on the Hydrocarbon Manifold Gauges.
Burnt oil looks dark and smells sharp. Teachers pass round a sample from a failed compressor next to clean oil, and students confirm the acid with the Acid Test Kit For All Refrigeration Oils. The class then decides whether the circuit also needs a new Filter Drier.
Frequently Asked Questions
Can mineral oil be used with R-134a or R-410A?
No. HFC refrigerants such as R-134a and R-410A do not mix with mineral oil. The oil stays in the evaporator and the compressor runs short of lubrication, so HFC systems use POE oil.
How much oil goes back in after a compressor change?
Drain the old compressor into a measuring cylinder and note how much came out. Many new compressors already hold their oil charge, so check the label or data sheet first. Add only what the maker gives, since too much oil does as much harm as too little.
Is this the same as vacuum pump oil?
No. Vacuum pump oil fills the sump of the pump and never enters the refrigeration circuit. Refrigeration oil is refined and dried to work inside the sealed system with the refrigerant, so the two should not be swapped.
Do hydrocarbon systems use mineral oil?
Many do. R-600a and R-290 mix well with mineral oil, and a lot of domestic R-600a compressors leave the factory filled with it. Some hydrocarbon compressors use other oils, so read the compressor label first.
