L-DRB Series Refrigeration Oil
Multi-Refrigerant Compressor Oil
Features excellent low-temperature fluidity and chemical stability, preventing oil solidification and system blockages in low-temperature environments, along with good lubricity and oxidation resistance for stable refrigeration equipment operation.
Product description
Product performance: Excellent low-temperature performance, with stringent pour point and flocculation point specifications ensuring the oil does not solidify in low-temperature components of refrigeration systems such as evaporators, allowing the compressor to deliver effective low-temperature cooling efficiency without wax deposits or system blockages. Superior chemical stability prevents reactions with refrigerants or other materials in the system, ensuring a long service life. Excellent lubricity, enhanced with a balanced additive package, provides improved anti-oxidation and anti-wear properties, ensuring reliable operation of refrigeration equipment under various conditions. Appropriate refining depth prevents carbon deposits at high-temperature parts like valves, avoiding pipeline blockages. Good cleanliness, with a clear and pure oil that cleans working components, effectively preventing impurity particles from abrading bearing surfaces. Application: Suitable for lubricating mechanical refrigeration equipment in contact with refrigerants. Users can select the appropriate grade of refrigeration oil based on equipment type, refrigerant used in the system, and system operating conditions.
