REF N Series Refrigeration Oil (MO)
▌Product description
Specifically developed for applications using ammonia as a refrigerant, the REF N series has a low pour point at very low temperatures and excellent fluidity due to virtually no wax. It also helps ensure that evaporator tubes are kept clean to improve heat transfer and reduce maintenance downtime. Good chemical stability is suitable for cylinder and bearing lubrication.
▌Performance characteristics
- Low wax content-excellent low-temperature fluidity for improved system effciency
- Sound chemical stability-long service life, less downtime, low maintenance costs
- Seal compatibility-long seal life, reducing shaft seal leakage
- Multi-purpose lubricant-Lubrication for cylinders and bearings reduces lubricant inventory
▌Performance characteristics
- It is suitable for R717 (ammonia), hydrocarbon refrigerants (such as R290, etc.), R744 (CO2)
- Reciprocating and screw-type compressor
