TotalEnergies LUNARIA NH 46 – Refrigeration Compressor Oil
LUNARIA NH 46 is a hydrocracked mineral oil designed for refrigeration compressors using ammonia (R-717) as refrigerant. It provides excellent oxidation stability even in non-hermetic systems and prevents the formation of deposits or sludge.
Product Advantages
• Excellent oxidation resistance, even in open systems
• No formation of deposits or sludge
• Low pour points prevent oil solidification and ensure heat transfer
• Extended oil drain intervals thanks to hydrocracked base oil
Typical Applications
• Reciprocating and screw compressors with ammonia (R-717, NH₃)
• Evaporation temperatures down to –30 °C
• Preferred use in industrial refrigeration plants
