Pure Refrigeration Lubricating Oil
Refrigerator oil is a lubricant specifically used in refrigeration equipment (such as refrigerators, air conditioners and freezers), and its main functions include lubrication, cooling, sealing and corrosion protection. It extends the service life of the equipment by reducing the friction of the moving parts in the refrigeration system; at the same time, it helps to carry away the heat generated during the refrigeration process and maintains the normal working temperature of the equipment.
Product Details：Pure Refrigeration Lubricating Oil
Refrigerator oils create a seal within the compressor, which helps prevent refrigerant leaks and enhances the overall efficiency of the system. Various types of refrigerator oils, such as mineral and synthetic oils, possess distinct characteristics that make them suitable for different refrigerants and operational conditions. Selecting the appropriate refrigerator oil is essential for maintaining the efficient and stable functioning of the refrigeration system, ultimately improving the equipment's performance and reliability.

1. Optional Points
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.
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. Factors Affecting Replacement Cycles
Manufacturer's Recommendations: Manufacturers often give recommendations for refrigeration oil change intervals based on equipment characteristics and usage. These recommendations are usually based on the manufacturer's knowledge of the equipment and test data, and therefore have a high reference value.
Type of equipment and operating environment: Different types of refrigeration equipment and different operating environments will have an impact on freezer oil change intervals. For example, industrial large-scale refrigeration units and domestic refrigerators may differ in the replacement cycle of freezer oil. At the same time, the temperature, humidity, dust and other factors in the use of the environment will also have an impact on the service life of the freezer oil.
