York 011-00533-000 Lubricating Oil/K OIL

POE (polyol ester) refrigerant oil, due to its excellent compatibility with HFC-type environmentally friendly refrigerants, outstanding performance in both high and low temperatures, and excellent lubrication stability, has become the mainstream lubricating oil in the global refrigeration and air conditioning industry. The core application areas are as follows:

 1. Commercial central air conditioning and industrial refrigeration systems

This is the core area with the largest usage of POE oil, widely used as the lubricant for centrifugal and screw type chillers from brands such as York, Carrier, and Trane, and also applied in industrial process refrigeration units in fields such as chemical, pharmaceutical, and electronics manufacturing. It is compatible with mainstream environmentally friendly refrigerants such as R134a, R407C, and R1234ze, meeting the lubrication and heat exchange requirements for large-scale units to operate continuously for a long time, and compatible with the economizer, multi-stage compression, and other complex system structures of the units.

2. Cold chain logistics and low-temperature refrigeration equipment

Suitable for various high and low-temperature cold storage, rapid freezing tunnels, supermarket refrigeration and freezing cabinets, refrigerated containers, and road cold chain transportation refrigeration units. Thanks to its extremely low pour point and excellent low-temperature fluidity, POE oil does not have wax precipitation below -40°C, allowing it to smoothly return to the compressor with the refrigerant, avoiding oil deficiency in low-temperature pipelines or blockage of throttling elements, and ensuring the long-term stable operation of the low-temperature system.

3. Light commercial and residential refrigeration air conditioning

Applied to commercial multi-split units, unit air conditioners, variable frequency household air conditioners, as well as refrigeration display cabinets, ice-making machines, commercial kitchen refrigeration equipment, etc. It is particularly suitable for the wide-speed operation conditions of variable-frequency compressors, with a strong oil film bearing capacity, which can reduce component wear at high speeds, and has good compatibility with system seals, heat exchangers, and metal materials.

4. High-end precision refrigeration scenarios

Widely used in data center precision air conditioners, medical low-temperature storage equipment, semiconductor manufacturing clean refrigeration systems, etc. These scenarios have extremely high requirements for reliability and cleanliness. POE oil has strong thermal oxidation stability and extremely low impurities and ash content, making it less prone to coking and deterioration during long-term operation, ensuring the continuous and stable operation of high-precision refrigeration systems.
