Refrigeration Compressor Oils
Designated for the intricate workings of refrigeration compressors, refrigeration oil, or simply put, compressor lubricant, fulfills a vital role in lubricating the heart of any cooling equipment—the compressor. This ensures smooth and energy-efficient operation, underpinning the reliability and longevity of the system.
Product Details：Refrigeration Compressor Oils
Refrigeration oil assumes a pivotal role in maintaining the optimal functioning of refrigeration equipment. It significantly influences not only the operational efficiency and longevity of the compressor but also the overall stability and dependability of the refrigeration system. Thus, when selecting and employing refrigerator oil, a comprehensive assessment must be conducted, taking into account the specific demands of the refrigeration apparatus and its operational environment.

1. Specifications:
GB/T 16630-1996.
2. Optional Points：
(1) Refer to the manufacturer's recommendations: Manufacturers often provide information on recommended brands, models and specifications for freezer oils. These recommendations are based on the manufacturer's knowledge and testing of their own equipment and are therefore highly informative.
(2) Specification standards: Choose a refrigerator oil that meets relevant specifications and certification requirements, such as the international standard ISO 6743-3 and the specifications set by the manufacturer.
(3) Environmental performance: Consider the environmental friendliness of the freezer oil and choose the product that meets the environmental standards to minimize the pollution and damage to the environment.
(4) Types: Refrigeration machine oils are mainly of mineral oil, synthetic oil (such as POE, polyalphaolefin) and vegetable oil types. Choose the appropriate type according to the type of compressor and working conditions.
3. Difference between freezer oil and lubricant use environment:
(1) Refrigerator oil: It is mainly applicable to the refrigeration compressor under low temperature environment. Under low temperature conditions, freezer oil needs to maintain good fluidity and lubrication performance to ensure that the compressor can operate normally and efficiently.
(2) Lubricating oil: it is suitable for mechanical equipment under various temperatures and environments. Whether it is high temperature, high pressure or low temperature, low pressure conditions, lubricants can play its lubrication and protection to meet the operational needs of different equipment.
