Premium line of industrial-grade evaporators, copper fittings, accumulator mufflers, and capillary assemblies trusted by global OEM giants.
A comprehensive overview of heat-exchange engineering requirements, global environmental challenges, and technological transitions.
As the international HVAC industry phases out high-GWP (Global Warming Potential) refrigerants in favor of eco-friendly alternatives like R32, R290 (propane), and CO₂ (R744), system pressures have risen dramatically. Under high pressure, material structural integrity becomes paramount. Precision-grade C12200 phosphorus-deoxidized copper tubing ensures low corrosion and leak-proof resilience under stress.
Industrial condensers and evaporators now utilize inner-grooved ACR tubes rather than smooth-bore tubes. The micro-grooved inner structure maximizes fluid contact area, inducing localized turbulence that prevents laminar boundary layers. This mechanical enhancement improves the overall thermal heat transfer coefficient by up to 30%, satisfying ErP and SEER eco-design requirements globally.
Refrigeration loop failures account for considerable environmental damage and costly refrigerant recharges. The industry has adopted helium-leak testing and automated CCD optical inspection systems to screen copper-brazed joints, filter drier closures, and capillary-elbow unions. High-purity welds and clean inner dimensions prevent capillary blockages and system failures.
A legacy of refrigeration accessories development rooted in technology and research partnership.
Ningbo Taojun Refrigeration Equipment Co., Ltd. is located in Xiangshan, Ningbo, a beautiful tourist city. Founded in 1988, its predecessor was Xiangshan Refrigeration Accessories Factory of Zhejiang University. The company's leading products include: filter driers, check valves, air conditioning valves, condensers, brass and copper accessories, air conditioning cable ties, and other refrigeration accessories series products.
After 30 years of hard work and rapid development, it has now become a comprehensive enterprise integrating the design, development, production, sales, and after-sales service of refrigeration accessories. In 2021, we became a national high-tech enterprise. Our company is committed to technological and process innovation, equipment improvement, and the introduction of advanced management concepts to produce first-class products.
Customer satisfaction is our unwavering pursuit. With reasonable design, reliable quality, and perfect after-sales service, the "Lingshan" filter has become a well-known brand in the domestic refrigeration industry. The company has successively passed ISO9001:2008 quality management system certification, EU ROHS environmental protection directive certification, and US UL certification. The company always takes customer needs as the basis and continuously innovates management concepts to ensure efficient and stable development.
In 2012, Ningbo Taojun Refrigeration Equipment Co., Ltd. was established, creating the brand "Taojun" condensers, "Taojun" stop valves, and other series of products. Over the years, it has established partnerships with well-known domestic and foreign home appliance enterprises such as Haier, Xinfei, Midea, Gree, Whirlpool, Electrolux, and Huarui. The product sales network covers major and medium-sized cities in China and is exported to Europe, America, South America, Southeast Asia, the Middle East, Africa, and other overseas markets. The company's goal is to support and cooperate with every sincere customer to achieve a win-win situation.
Specializing in HVAC/R components engineered to capture system moisture, neutralize acid, and eliminate structural blockages.
Taojun has specialized in manufacturing refrigeration components for 38 years. Our core offerings span filter driers, access valves, and high-efficiency condensers. Our copper filter driers are designed to absorb moisture and acid, and to filter out impurities. Typically installed as standard equipment or replaced as maintenance parts for both domestic and commercial refrigerators, freezers, and air conditioners.
Uncompromising engineering standards backed by institutional partnerships and high-tier equipment lines.
Our core production systems are imported directly from Germany, ensuring precise tolerance controls (±0.02mm for aluminum and copper dimensions) and repeatable metal forming capabilities.
Our engineering division employs 15 core specialists, including doctors and researchers from the University of Science and Technology of China and Zhejiang University, pushing boundaries in high-efficiency flow dynamics.
We provide full customization for structural shapes, copper pipe wall configurations, core capacities, and connection designs. We bring system-level HVAC/R conceptual models to physical reality.
We source Japanese-imported ITO film with zero heat-shrinkage and European-formulated industrial bonding agents. The liquid crystal spacers ensure dimensional uniformity while the protective layers tolerate temperatures from 80°C to 90°C.
Our verification processes subject parts to 500-hour environmental aging tests (-35°C to 75°C), thermal shock cycling (10°C to 90°C for 30 minutes), and 100V high-voltage insulation tests for zero breakdown.
Our GB/T19001-2016/ISO9001:2015 certification (Registration No.: 41325Q00065R0S) guarantees tracing from initial melting, extrusion, machining to final leak testing phases.
A tour across our MES-driven workshops, assembly modules, and advanced validation labs.
