Direct factory supply chain integration supporting commercial, residential, and industrial cooling networks.
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. Over 30 years of hard work and rapid development, it has now become a comprehensive enterprise integrating the design and development, production, sales, and after-sales service of premium refrigeration components and brackets.
In 2021, Taojun achieved recognition as a National High-Tech Enterprise. Our commitment to technological and process innovation, equipment improvement, and the introduction of advanced management concepts has made us a leading global supplier. With reliable design, strict quality control, and robust support structure, our flagship products, including the "Lingshan" filter and "Taojun" refrigeration parts, are household names in the domestic and global industrial sectors.
In 2012, Ningbo Taojun established specialized lines for the brand "Taojun" condensers, "Taojun" stop valves, and various HVAC wall-mounting solutions. Today, we hold long-term strategic relationships with global market leaders such as Haier, Xinfei, Midea, Gree, Whirlpool, Electrolux, and Huarui. Our global logistics footprint reaches markets in Europe, America, South America, Southeast Asia, the Middle East, and Africa.
Expert manufacturing of copper filter driers, check valves, and outdoor support brackets engineered for extreme operating demands.
TAOJUN copper filter driers are precision-formulated to absorb moisture and system acid, filtering out micro-impurities. Essential for system integrity in domestic and commercial refrigeration circuits.
Integrating optimized flow corridors, thermal conductivity fins, and high-purity copper pipelines. Ensures dynamic heat transfer and system energy efficiency under heavy outdoor ambient loads.
Precision-stamped wall brackets engineered to withstand mechanical load stresses, wind loads, and galvanic corrosion challenges in high-humidity coastal and industrial climates.
Leveraging advanced German automation, Japanese premium raw materials, and extreme thermal testing protocols to secure a zero-breakdown operational standard.
Our core production facility is directly equipped with high-tech automated machining machinery imported from Germany, ensuring sub-micron dimensional tolerances and uniform product quality.
Our collaborative R&D team includes 15 expert engineers holding doctorates and professorships from the University of Science and Technology of China (USTC) and Zhejiang University.
We source ITO films (zero shrinkage, no color difference) and liquid crystal spacers directly from Japan. Adhesives are sourced from specialized EU chemical suppliers, with high-temperature resistance up to 90°C.
Every refrigeration and mounting component undergoes high and low temperature tests ranging from +75°C down to -35°C for 500 consecutive hours. Thermal shock testing shifts components from 10°C to 90°C in 30 minutes, backed by 100V high-voltage insulation tests for smart controllers.
We support fully customized product dimensions, metal gauges, and configurations. Sharing a vision with our partners, we accelerate prototypes from design boards to trial batches with a rapid development cycles.
Ningbo Taojun has spent over four decades mastering copper drying, structural sheet metal stamping, and safety control design. The primary competitive advantage that has secured our industry standing is technology.
Shell: High-purity copper pipeline (extremely rust-resistant, high-pressure rating). Support brackets utilize structural steel with heavy hot-dip galvanized coating profiles.
Inner Core: Premium 3A molecular sieve showing water absorption capacity ≥ 20%, paired with a highly effective activated carbon layer. Welding: Argon arc shielding ensuring leak-free joints.
Drastically lowers compressor mechanical wear by capturing moisture and corrosive acids. Improves refrigeration cycle speed by maintaining system pressure stability.
Analyzing the structural, material, and system shifts defining the future of climate control installations globally.
Modern variable-speed inverters change the frequency profile of vibrations transferred to buildings. Future support structures integrate viscoelastic compounds and variable-tension springs that actively shift dampening characteristics, eliminating structure-borne noise.
As microclimates grow harsher, basic hot-dip galvanization is giving way to Zn-Al-Mg (Zinc-Aluminum-Magnesium) self-healing steel. In the event of surface scratches during installation, the active metal elements migrate to seal the exposed surface, preventing rust formation.
Next-gen refrigerants like R32 and CO₂ (R744) work at significantly higher pressures. Brackets and copper accumulators must be designed to withstand severe thermal expansion cycle fatigue and physical impact stress.
Outdoor AC brackets must perform reliably in diverse and harsh environments. A structural bracket failure can damage building facades, cause severe personal injury, and destroy multi-thousand-dollar HVAC hardware.
Coastlines and High Salt Zones: High humidity and chloride ions accelerate rust in standard steel. Taojun’s specialized C5-M marine-grade powder-coated brackets resist corrosion for over 15 years under aggressive salt spray testing conditions.
Seismic and Wind Resistance: In high-rise urban centers, brackets must withstand strong shear forces. Our FEA (Finite Element Analysis) verified structural brackets are load-rated to withstand category 5 hurricanes without metal fatigue or bracket deformation.
How integration of MES planning software, visual automated inspections, and logistics routing safeguards high-volume orders.
Our Manufacturing Execution System (MES) schedules manufacturing runs, tracks material lots from raw steel coil to finished bracket, and reduces material lead times by 30%.
High-resolution optical cameras scan products for surface anomalies, dimensional variations, or paint finish scratches, rejecting defective parts automatically.
Direct supply contracts with Chinese steel mills shield Taojun and our global buyers from volatility in steel and copper prices.
Our team believes a global brand must be supported by a strong corporate culture. We understand that a company's identity is formed over time through cultural impact, infiltration, and integration.
Honesty: We adhere to the principle of people-oriented, integrity-focused management. Honesty is the foundation of our competitiveness, guiding every business step we take.
Innovation: Innovation is the core of our culture. It drives development, increases strength, and keeps our operations agile and ready for emerging opportunities.
Responsibility: We hold a strong sense of responsibility toward our clients, our employees, and society. This commitment is the driving force behind the development of our group.
Cooperation: We strive to build a cohesive corporate environment. Working together to create win-win situations ensures resource integration and mutual growth with our partners.
Securing building permissions for industrial and residential HVAC units requires compliance with local structural codes. Importing structural elements demands verifiable material safety certifications.
GB/T19001-2016/ISO9001:2015 Compliance: Our manufacturing facility operates under audit certification 41325Q00065R0S, ensuring standard design and build parameters across our entire range of filter driers, condensers, and mounting assemblies.
Environmental Compliance: Our raw material inputs comply with European RoHS, REACH, and WEEE directives, minimizing chemical contaminants and utilizing fully recyclable packaging options.
