Applications

Lunaria SH 46 is designed for lubricating refrigerating compressors (reciprocating and screw) that use ammonia as a refrigerant.

  • Formulated with PAO (polyalphaolefin) base oils to enhance oil drain intervals and ensure optimal performance, even at extremely low temperatures.
  • Suitable for evaporator temperatures down to -50°C.

Advantages

  • Superior oxidation resistance in ammonia environments. The synthetic base oil and specialized additives prevent the formation of black sludge caused by oil-ammonia reactions.
  • Low pour point, preventing residual lubricant from freezing in the evaporator, ensuring efficient heat exchange.
  • Low volatility and high flash point, reducing oil consumption by 30-50% compared to conventional oils.
  • Storage Precaution: Prevent water contamination, as water presence can block the evaporator.

Specifications

  • Complies with ISO 6743-3 DRA and DIN 51503 KA standards.
  • NSF-H1 registered:
    • Lunaria SH 46 – Certificate No. 139826
