Manufactured with high-quality synthetic ester base oil and compound functional additives, it complies with strict Q/SH303 178—2004 industry standards and matches international premium refrigeration oil performance benchmarks.
This oil series features an ultra-wide adaptive temperature range of -40°C to 150°C, withstanding short-term peak temperatures up to 170°C. It achieves excellent miscibility with mainstream HFC refrigerants including R134a, R407C, and R410A. Perfectly compatible with scroll, screw, and reciprocating compressors, it is widely applicable for new equipment filling and old system oil replacement and maintenance, serving as a reliable universal lubrication solution for modern refrigeration systems.
Core Technical Advantages & Product Features
-
Superior Thermal & Oxidative Stability The high-purity synthetic ester base oil effectively resists high-temperature oxidation and oil deterioration during continuous compressor operation. It greatly reduces carbon deposit and sludge formation on valve plates, cylinder walls, and heat exchanger surfaces, extending oil change intervals and avoiding system failures caused by lubricant aging.
-
Excellent Refrigerant Miscibility & Solubility It maintains stable miscibility with common HFC refrigerants across low and medium temperature ranges. It prevents oil logging in evaporators and condensers, ensures smooth oil circulation in the closed refrigeration loop, and preserves optimal heat transfer efficiency of the entire system.
-
Ultra-Wide Temperature Adaptability With ultra-low pour point and excellent low-temperature fluidity, it guarantees no wax precipitation and stable lubrication in ultra-low-temperature refrigeration environments. Meanwhile, it maintains stable viscosity and structural performance under long-term high-temperature discharge conditions, adapting to variable and harsh working conditions.
-
Reliable Anti-Wear & Extreme-Pressure Protection Formulated with efficient extreme-pressure and anti-wear additives, it forms a dense protective oil film on compressor friction pairs. It reduces metal friction and wear under high-load operation, effectively extending compressor service life and lowering equipment failure rates.
-
Excellent Material Compatibility It features excellent adaptability with rubber seals, gaskets, and non-metallic components inside compressors. It avoids seal swelling, aging, and leakage risks, ensuring long-term airtight and stable operation of hermetic and semi-hermetic refrigeration systems.
-
Anti-Corrosion & Rust Prevention Performance Unique anti-corrosion formula isolates moisture and acidic substances in the system, preventing metal component rust and electrochemical corrosion. It provides comprehensive protection for internal compressor parts and pipeline systems.
-
Eco-Friendly & Good Biodegradability Compared with traditional mineral refrigeration oil, the 4524 synthetic series boasts better biodegradability, lower environmental pollution risk, and meets global environmental protection and green manufacturing standards.
-
Cost-Effective Import Replacement Its overall performance is equivalent to internationally renowned refrigeration oil products such as Emkarate RL and Castrol Icematic SW series. It provides the same stable operational performance with more competitive pricing, greatly reducing long-term equipment operation and maintenance costs.
Main Industrial & Commercial Application Scenarios
With comprehensive performance and wide compatibility, Great Wall 4524 series synthetic refrigeration oil covers almost all mainstream commercial and industrial refrigeration and HVAC scenarios:
1. Commercial Central HVAC & Chiller Systems
Ideal for large water chillers, rooftop air conditioning units, and central air conditioning systems in hotels, shopping malls, office buildings, and hospitals. It perfectly matches scroll and screw compressors running on R134a, R407C, and R410A refrigerants, ensuring stable long-term operation of commercial HVAC equipment and reducing energy consumption and maintenance frequency.
2. Industrial Refrigeration & Cold Storage Projects
Widely used in low-temperature cold storage, freezing warehouses, food processing refrigeration, and industrial process cooling systems. Its excellent low-temperature fluidity prevents lubricant solidification in ultra-low-temperature environments, ensuring continuous and efficient operation of industrial refrigeration units all year round.
3. Petrochemical & Industrial Cryogenic Systems
Suitable for petrochemical cryogenic recovery equipment, industrial tail gas cooling systems, and special process refrigeration units. It adapts to high-load and variable temperature industrial working conditions, solving lubrication failure problems of ordinary refrigeration oil under harsh industrial environments.
4. Automotive & Mobile Air Conditioning Systems
Applicable to vehicle air conditioning and mobile refrigeration equipment. It copes with frequent temperature fluctuations and variable load operation during vehicle driving, providing stable lubrication and protection for mobile refrigeration compressors.
5. Equipment Maintenance & System Retrofit Projects
It is the preferred replacement oil for old refrigeration system maintenance, compressor overhaul, and system flushing. It can fully replace imported high-priced refrigeration oils, helping engineering teams and end users achieve low-cost and high-quality system upgrades and daily maintenance.
Risks of Using Substandard Refrigeration Oil
-
Compressor Abrasion & Shortened Service Life: Insufficient anti-wear performance causes long-term friction damage to core components
-
Carbon Deposit & System Blockage: Poor oxidation resistance leads to oil aging and sludge accumulation, blocking pipelines and heat exchangers
-
Reduced Refrigeration Efficiency: Poor refrigerant miscibility causes oil accumulation in heat exchange areas, increasing thermal resistance
-
Seal Aging & Refrigerant Leakage: Incompatible oil corrodes seals, triggering system leakage and operational failures
-
Frequent Maintenance & High Operational Costs: Short oil replacement cycles increase equipment downtime and maintenance expenses
