Stable lubrication is the cornerstone of long-cycle, fault-free operation for refrigeration compressors. Many traditional mineral oils suffer from poor low-temperature fluidity, severe high-temperature oxidation, unstable oil return, and incompatibility with old-generation refrigerants, leading to carbon deposit buildup, compressor wear, oil sludging, and unexpected system shutdowns. Great Wall 4523 Series Synthetic

Refrigeration compressor oil is the core protective medium that determines the stability, efficiency, and service life of HVAC and industrial refrigeration systems. Inferior lubricants often cause high-temperature oil degradation, carbon deposit accumulation, poor refrigerant compatibility, and compressor wear, leading to frequent system failures, reduced heat exchange efficiency, and costly equipment

pH value is the core fundamental indicator that determines the operating state of industrial circulating water systems, HVAC cooling towers, boiler water loops, and industrial wastewater treatment lines. Long-term cyclic concentration, chemical agent dosing, microbial metabolism, and industrial process infiltration easily cause severe pH imbalance. Excessively acidic water triggers metal

High-temperature industrial circulating water systems, boiler equipment, petrochemical pipelines, and seawater desalination facilities face severe scaling, sludge deposition, and medium corrosion challenges under long-cycle and high-load operation. Conventional water treatment dispersants often fail at high temperatures and high alkalinity, leading to hard scale accumulation, reduced heat exchange efficiency, pipeline blockage,

Industrial open and closed circulating water systems, including HVAC cooling towers, industrial boilers, chemical process water, and petroleum & steel plant cooling loops, constantly accumulate mineral microcrystals, suspended silt, corrosion sediments, and organic impurities during long-term operation. These tiny particles easily agglomerate, settle, and adhere to pipe walls and heat

Industrial circulating water systems, central HVAC cooling systems, industrial boilers, and metal pipeline networks face continuous threats of electrochemical corrosion, rust oxidation, scale deposition, and pipeline aging. After routine descaling and cleaning, bare metal surfaces lose protective layers and become extremely active, easily reacting with oxygen, moisture, and mineral ions
