What Is Great Wall 4523 Series Synthetic Refrigeration Oil?
Great Wall 4523 Series is a professional synthetic refrigeration compressor oil built with premium alkylbenzene base oil and compounded with extreme-pressure, anti-oxidation, anti-corrosion, and anti-foam additives. It covers complete ISO viscosity grades including VG32, VG46, VG56, VG68, and VG100, meeting diverse lubrication demands from light commercial cooling to heavy-duty industrial low-temperature refrigeration.
Distinct from ester-based 4524 series, the 4523 series features outstanding compatibility with traditional refrigerants including R11, R12, R23, R22, and ammonia (NH3). It supports an ultra-wide operating temperature range of -50°C to 150°C, withstanding short-term peak temperatures up to 170°C. With excellent low-temperature fluidity and anti-sludging performance, it is the optimal lubrication solution for conventional and low-temperature industrial refrigeration systems.
Core Technical Advantages & Product Features
-
Industry-Leading Thermal & Oxidative Stability The high-purity alkylbenzene synthetic base oil resists high-temperature deterioration and oxidative degradation during long-hour continuous compressor operation. It effectively inhibits sludge, carbon residue, and varnish formation on valve plates, cylinder walls, and heat exchangers, keeping internal compressor components clean and extending oil change intervals significantly.
-
Exceptional Low-Temperature Fluidity & Oil Return Featuring ultra-low pour point and flocculation point, the 4523 series avoids wax precipitation and oil condensation under ultra-low temperature working conditions. It ensures smooth and rapid oil return in evaporators and long-distance pipelines, eliminating oil logging issues and maintaining stable heat exchange efficiency for low-temperature refrigeration systems.
-
Broad Refrigerant & System Compatibility Perfectly compatible with CFC, HCFC, and ammonia refrigerants, it matches all traditional mainstream refrigeration systems worldwide. It adapts to reciprocating, rotary, screw, and piston compressors of fully enclosed, semi-hermetic, and open types, with strong universality for old and new refrigeration equipment.
-
Superior Anti-Wear & Extreme-Pressure Protection Unique extreme-pressure additive formula forms a dense, durable protective oil film on metal friction pairs. It reduces mechanical wear and friction loss under heavy-load and variable-load operation, effectively extending compressor service life and lowering equipment failure rates.
-
Excellent Anti-Foam & Anti-Cavitation Performance Outstanding defoaming property prevents oil hammer and cavitation phenomena inside compressors, avoiding operational vibration, pressure fluctuation, and component damage caused by foam accumulation, ensuring stable and safe system operation.
-
Reliable Anti-Corrosion & Material Adaptability It effectively isolates moisture and acidic substances generated by refrigerant decomposition, preventing metal rust and electrochemical corrosion. Meanwhile, it is friendly to rubber seals, gaskets, and non-metallic parts, avoiding swelling, aging, and refrigerant leakage risks.
-
Cost-Effective Import Replacement Its overall performance fully meets international KC and DRB grade standards, capable of replacing high-priced imported refrigeration oils. It helps global end users and contractors reduce long-term equipment operation and maintenance costs without sacrificing system reliability.
Main Industrial & Commercial Application Scenarios
With ultra-wide temperature adaptability and strong refrigerant compatibility, Great Wall 4523 series is widely applied in full-scenario commercial and industrial refrigeration systems, especially suitable for low-temperature and ammonia refrigeration projects:
1. Industrial Low-Temperature Cold Storage Systems
Ideal for large frozen warehouses, food cold chain storage, and low-temperature logistics refrigeration equipment. Its excellent low-temperature fluidity ensures stable lubrication at -50°C ultra-low temperature, solving oil solidification and poor oil return problems of ordinary mineral oils, supporting 24/7 continuous operation of cold storage compressors.
2. Ammonia Industrial Refrigeration Projects
Specially applicable for industrial refrigeration systems using ammonia as refrigerant, widely used in petrochemical, pharmaceutical, food processing, and chemical plant process cooling. It delivers stable anti-corrosion and lubrication protection for open and semi-hermetic ammonia compressors, adapting to harsh industrial working conditions.
3. Commercial HVAC & Chiller Units
Suitable for central air conditioning systems, water chillers, and rooftop AC units in office buildings, shopping malls, and hotels. It matches R22 and traditional HCFC refrigerant systems, ensuring stable operation of reciprocating and rotary compressors and reducing daily maintenance failures.
4. Mobile & Special Refrigeration Equipment
Perfect for vehicle air conditioners, refrigerated truck cooling units, and mobile refrigeration equipment. It copes with frequent temperature fluctuations and variable load operation during driving, providing reliable shock-resistant lubrication and protecting mobile compressors from wear and failure.
5. Household & Commercial Refrigeration Devices
Applicable for refrigerators, freezers, display cabinets, and small commercial refrigeration equipment. Stable performance ensures long-term quiet and efficient operation of small enclosed compressors, reducing daily energy consumption and failure rates.
6. Old Refrigeration System Renovation & Maintenance
It is the preferred replacement oil for legacy refrigeration equipment renovation, compressor overhaul, and system oil flushing. It perfectly matches old-generation refrigerant systems that cannot adapt to ester-based oils, realizing low-cost and high-stability system upgrades.
Risks of Using Substandard Refrigeration Oil
-
Poor Low-Temperature Oil Return: Ordinary oils solidify at low temperature, causing oil logging and reduced refrigeration efficiency
-
High-Temperature Carbon Deposits: Thermal oxidation failure leads to sludge accumulation and pipeline blockage
-
Refrigerant Incompatibility: Unmatched lubricants cause seal swelling, aging, and refrigerant leakage
-
Compressor Abrasion & Shortened Lifespan: Insufficient extreme-pressure protection accelerates core component wear
-
Frequent Foam & Oil Hammer: Poor anti-foam performance triggers system vibration and operational faults
