  • Superior Thermal & Oxidation Stability: Resists carbon and sludge formation, maintaining oil cleanliness and extending equipment life.
  • Wide Operating Conditions: Suitable for semi-hermetic compressors, central AC systems, chillers, screw compressors, and high-temperature applications. Maintains good low-temperature flow.
  • Corrosion Protection: Contains corrosion inhibitors to protect metallic compressor parts, enhancing reliability.

Technical Specifications

  • Complies with mineral oil-based refrigeration compressor oil industry standards.
  • Fully compatible with R22 refrigerant systems.
  • Viscosity grades selected according to compressor type and operating conditions.
  • Ensures efficient, safe, and reliable operation of refrigeration equipment.

Applications

  • L-DRA/A 32: Semi-hermetic compressors for small commercial refrigeration, household AC, and small commercial freezers.
  • L-DRA/A 46: Central air conditioning systems, chillers for commercial buildings, malls, offices, and factories.
  • L-DRA/A 68: Screw compressors and high-temperature industrial refrigeration equipment, such as industrial high-temperature cold storage and large-scale refrigeration units.

Storage & Handling

  • Store in a cool, dry, ventilated area away from direct sunlight and heat sources.
  • Keep containers tightly sealed to prevent moisture or dust contamination.
  • Use the correct viscosity grade for the specific equipment and operating conditions.
  • Wear protective gloves during handling; in case of skin contact, rinse thoroughly with water.
  • During oil replacement, completely drain old oil and flush the system before adding new oil.

Notes

  • Specifically designed for R22 refrigerant systems; do not mix with other refrigerants (e.g., R134a, ammonia) or incompatible compressor oils.
  • Packaging options accommodate small equipment top-up (16L) or large industrial systems (200L).
  • Optimal performance requires selecting the appropriate viscosity grade per equipment manufacturer recommendations or operational needs.
