Direct access to certified OEM/ODM industrial parts engineered for durability, leakage control, and thermodynamic compliance.
Founded in 1988, Ningbo Taojun Refrigeration Equipment Co., Ltd. (located in Xiangshan, Ningbo, a scenic coastal city) evolved from the prestigious Xiangshan Refrigeration Accessories Factory of Zhejiang University. For over 30 years, our enterprise has integrated design, engineering, advanced manufacturing, and technical customer care to supply premium components to the global thermal management and HVACR markets. In 2021, we were officially recognized as a National High-Tech Enterprise, emphasizing our focus on technological innovation and product safety.
Our comprehensive production facility manufactures advanced copper and aluminum accessories, including filter driers, check valves, air conditioning valves, wire tube condensers, and specialized copper fittings under the domestic leader brand "Lingshan" and our specialized global brand "Taojun". Our business strategy centers on zero-defect manufacturing, continuous technological development, and robust partner support.
Through decades of rigorous quality maintenance, we have established long-term engineering and supply chain collaborations with major global home appliance brands, including Haier, Midea, Gree, Whirlpool, Electrolux, Xinfei, and Huarui. Our global export channels extend across Europe, North America, South America, Southeast Asia, the Middle East, and Africa.
With 38 to 41 years of specialized expertise in manufacturing copper filter driers and air treatment accessories, we guarantee optimal cooling system protection.
Our copper filter driers are engineered to protect domestic and commercial refrigerators, commercial freezers, and automotive AC systems. They efficiently capture chemical acids, system impurities, and operational moisture, ensuring system longevity and preventing capillary tube freezing.
Understanding the evolutionary trends in electric motors enables HVACR manufacturers to specify highly efficient, future-proof components.
Auxiliary fan motor systems are shifting from traditional shaded-pole architectures to brushless direct current (BLDC) and electronically commutated (EC) configurations. This transition achieves energy savings of up to 45% under partial load conditions, lowering total lifetime operation costs.
Integrating on-board microprocessors and sensors allows real-time monitoring of rotation speed (RPM), operating current, and bearing temperature. This enables predictive maintenance protocols and helps prevent unexpected system shutdowns.
Eco-friendly refrigerants like R290 (propane) and R744 (CO2) require non-sparking electrical assemblies. Future auxiliary fan motors feature ATEX-certified encapsulated coils and hermetically sealed connectors to guarantee safe operation.
Modern fan assemblies require a holistic design approach. By optimizing the stator-to-rotor spacing and implementing bionic blade geometries, our future lines aim to reduce turbulence-induced noise. This makes our motors ideal for noise-sensitive applications, including residential heat pumps and high-end commercial showcases.
Empowering global supply chains through advanced automation, rigorous raw material selection, and intelligent quality verification.
Our core production lines incorporate manufacturing equipment imported directly from Germany, enabling high-precision machining tolerances down to ±0.02mm. Operating under a comprehensive MES (Manufacturing Execution System), our workshop tracks product batches from raw copper coils to final leak tests.
We source ITO films, high-stability liquid crystal spacers, and high-purity copper directly from verified suppliers in Japan and Europe. This ensures uniform material behavior, zero shrinkage, and chemical compatibility with standard and eco-friendly refrigerants.
Our research and development team includes 15 expert engineers, including doctors and professors from the University of Science and Technology of China (USTC). This direct academic connection allows us to quickly integrate advanced thermodynamic calculations and material engineering research into our mass-production lines.
Customized product configurations designed to address the specific performance and regulatory demands of diverse refrigeration sectors.
Supplying high-efficiency single-phase shaded pole motors, roll-bonded aluminum plate evaporators, and compact copper filter driers (10g to 20g) optimized for domestic refrigerators and ice makers.
Providing high-capacity copper accumulators, robust condensers, and heavy-duty double copper filter driers. These components are designed to withstand high pressure and continuous operations in commercial freezers and supermarket displays.
Manufacturing durable air conditioning valves, charging safety valves, insulated copper tubes, and high-performance AC fan motor components capable of operating in extreme ambient temperatures (-35°C to 75°C).
We provide comprehensive supply chain support to streamline global procurement. Our Flexible Production Model supports OEM and ODM projects with a minimum order quantity (MOQ) of 500 units. This allows procurement teams to balance inventory cost risks while obtaining high-quality components.
Our strategic proximity to Ningbo and Shanghai ports enables rapid container consolidation. For emergency orders, we coordinate with air cargo networks to offer 72-hour global delivery, minimizing operational delays for our manufacturing partners.
Ensuring total compliance with environmental guidelines and international safety regulations to guarantee seamless import and integration.
Our quality management system is fully certified under the official GB/T19001-2016/ISO9001:2015 standards (Registration No.: 41325Q00065R0S). This verification covers the design, manufacture, and sales of filter driers, condensers, and access valves. It is searchable on the official CNCA database (www.cnca.gov.cn).
Additionally, our export lines are fully certified under EU RoHS, REACH, and US UL directives. These certifications guarantee that our components do not contain hazardous heavy metals or prohibited chemical plasticizers, making them ready for immediate integration in European and American factories.
