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 dries, 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 and development, production and sales, and after-sales service of refrigeration accessories. In 2021, it 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.
Providing cutting-edge manufacturing solutions for refrigeration pipe connectors, desiccant assemblies, and auxiliary HVAC control elements.
Taojun is specialized in refrigeration parts for over 38 years.
Our core lines encompass high-purity copper filter driers, copper access valves, condensers, and premium brass tee fittings. TAOJUN copper filter driers are optimized to absorb internal system moisture and destructive acid compounds while filtering physical impurities. They are vital components for installation and repair in domestic/commercial refrigerators and heavy-duty cold store units.
Our structural capabilities, technological research, and relentless quality control form the foundation of our client relations.
Our core manufacturing lines, auto-brazing machinery, and copper pipe cutting stations are imported directly from leading engineering firms in Germany.
We boast a research division comprising 15 senior design engineers. Many hold doctorates or professor posts from the prestigious University of Science and Technology of China.
We import our ITO films (zero shrinkage, zero color variance) and liquid crystal spacers directly from Japan. Our protective film layers resist temperatures up to 80-90°C.
All parts undergo thermal shock testing (10°C to 90°C for 30 min) and high/low-temperature aging (75°C to -35°C for 500 hours) to secure a field failure rate of under 0.05%.
We specialize in custom sizing, physical shaping, and customized branding for complex pipeline layouts and cooling systems. Share your design sheets with us.
Exporting to Europe, North America, South America, and Africa. Partnered with major appliance brands such as Midea, Gree, Haier, and Whirlpool.

A deep look at global HVAC/R demands, compliance, and material engineering advancements.
The global refrigeration industry is undergoing a transition toward environmentally friendly refrigerants (such as R32, R290, and CO2). This shift presents new challenges for copper fittings. Traditional copper alloys must be modified to withstand the higher operating pressures of green refrigerants without increasing pipe wall thickness. Global supply chains now demand strict compliance with RoHS, REACH, and WEEE directives, requiring manufacturers to provide complete material traceability from raw copper ingots to the finished equal tee.
Additionally, macro logistics challenges mean that OEMs require highly flexible manufacturing partners. Facilities must offer short lead times, reliable bulk packaging, and zero physical defects (achieved through automated vision inspection). Our facility in Zhejiang integrates raw material control with advanced manufacturing processes to meet these demands.
To support high-pressure designs, Taojun's R&D team focuses on key technical improvements:
By using automated CCD vision inspection and helium leak test systems, we check every run of copper equal tees and filter driers against micro-leakage down to 1x10⁻⁸ mbar·l/s. This helps ensure reliability in industrial HVAC installations.
Equipped with high-precision bending and extrusion lines.
Welding and sealing lines under continuous MES control.
Equipped to run 500-hour environmental and high-pressure stress tests.
