Engineered for high-pressure refrigerants including R410A, R32, and eco-friendly R290 systems.
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. Our 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 over 35 years of hard work and rapid development, it has now become a comprehensive enterprise integrating the design and development, production and 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.
With reasonable design, reliable quality, and perfect after-sales service, our "Lingshan" filter has become a well-known brand in the refrigeration industry. The company has successively passed ISO9001:2008 quality management system certification, EU ROHS environmental protection directive certification, and US UL certification.
Navigating the requirements of high ambient temperatures, energy efficiency schemes (BEE Star rating), and green refrigerants.
Driven by the "Make in India" initiative, the Production Linked Incentive (PLI) Scheme for White Goods, and massive investments in cold chain networks, India's demand for high-grade copper fittings is at an all-time high. Air conditioning systems in India face uniquely harsh conditions: extreme tropical heat waves exceeding 48°C, monsoon moisture, and voltage fluctuations. Consequently, residential and commercial refrigeration manufacturers require copper components that ensure zero leakage and withstand elevated operating pressures.
At Taojun, we design our copper fittings utilizing high-purity C12200 Deoxidized High Phosphorus (DHP) copper, which is the gold standard for refrigeration applications. This material guarantees excellent brazing characteristics, high thermal conductivity, and outstanding resistance to corrosion.
With India phasing out HCFCs (like R22) in favor of lower GWP alternatives such as R32 and natural hydrocarbon R290 (Propane), system pressures have risen considerably. Standard copper fittings are no longer sufficient. Our factory specializes in heavy-wall copper fittings specifically engineered to handle the high-pressure dynamics of R32 (often requiring up to 4.3 MPa testing pressures).
Over the decades, we have established long-term relationships with leading domestic and foreign home appliance giants including Haier, Midea, Gree, Whirlpool, Electrolux, and Huarui. Our logistics network is optimized to serve industrial clusters in Pune, Chennai, Noida, and Hyderabad.
How our advanced manufacturing floor translates to reliable lead times, lower tariffs, and uncompromising quality for Indian buyers.
Our main manufacturing and forming equipment is imported directly from Germany, ensuring precise cut tolerances (+/- 0.02mm) and zero internal scoring in the bending processes.
By integrating a central MES (Manufacturing Execution System), we track batches from copper cathode sourcing through melting, extrusion, stamping, wash, and pressure testing.
Located near Ningbo Port, one of the world's largest logistics hubs. We offer streamlined customs clearing, swift freight scheduling, and short ocean transit times to Chennai, Mumbai, or Kolkata.
For over 38 years, our focus has been providing copper filter driers and related HVAC accessories designed to protect critical compressor systems.
Our copper filter driers are designed to absorb moisture and acids, and to filter out physical impurities within the system. They are typically installed as a core component in brand-new systems or replaced as a critical service/repair part for domestic and commercial refrigerators, display cases, and freezers.
✓ Shell: High purity C12200 copper pipe (Highly rust resistant, excellent thermal conductivity, high-pressure certified).
✓ Inner Core: Premium 3A Molecular Sieve (water absorption ≥ 20%) combined with an activated carbon layer to prevent acid buildup.
✓ Sealing: Argon Arc welding process to ensure leak-free performance under pressure.
Wholesale orders and customized manufacturing directly from our factory floor.
