Specialized Oil For Refrigeration System
Refrigerator oil is a dedicated lubricant utilized in refrigeration equipment, which includes refrigerators, air conditioners, and freezers. Its key functions are lubrication, cooling, sealing, and corrosion protection. By lowering friction in the moving parts of the refrigeration system, it significantly increases the lifespan of the equipment. Additionally, it helps to eliminate heat generated during the refrigeration cycle, thus maintaining the equipment's normal operating temperature.
Product Details：Specialized Oil for Refrigeration System
Refrigerator oils form a seal in the compressor, preventing refrigerant leakage and thus increasing the efficiency of the system. Different types of refrigerator oils (e.g. mineral oils and synthetic oils) have different properties and are suitable for different refrigerants and operating conditions. Choosing the right refrigerator oil is crucial to ensuring the efficient and stable operation of the refrigeration system, which can effectively improve the performance and reliability of the equipment.

1. Optional Points
Viscosity: The viscosity of refrigerator oil is an important indicator of its fluidity performance. Select the appropriate viscosity according to the compressor speed, operating temperature and load. Generally speaking, the higher the speed of the compressor, the greater the viscosity of the refrigerator oil used should be.
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.
2. Factors Affecting Replacement Cycles
Type and quality of freezer oil: The type and quality of freezer oil is also an important factor in determining replacement intervals. Generally speaking, the service life of synthetic oil is relatively long, while the service life of mineral oil is relatively short. In addition, good quality freezer oil provides better lubrication and sealing properties, thus extending the replacement intervals.
