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 company is committed to technological and process innovation, equipment improvement, and the introduction of advanced management concepts to produce first-class products.
Over the span of more than three decades, Taojun has transitioned from a specialized academic workshop into a massive national high-tech enterprise. Today, our leading products include filter driers, check valves, air conditioning valves, wire-tube condensers, brass and copper accessories, and HVAC specialty tapes. Under our trademark "Lingshan", our components are trusted by premier global appliance brands including Midea, Gree, Haier, Whirlpool, and Electrolux.
Our operations conform to strict global standards, having attained ISO9001:2015 registration (No. 41325Q00065R0S), EU RoHS Environmental Protection Directive certification, and USA UL safety listings. We design with structural integrity to withstand volatile field conditions.
The commercial and industrial refrigeration market is experiencing rapid changes driven by environmental compliance, energy conservation directives, and the transition toward natural refrigerants (such as R290, R600a, and CO2). As a foundational component of these systems, the condenser's efficiency directly dictates the coefficient of performance (COP) of the entire system.
Modern HVAC designs demand tight control over subcooling parameters to prevent flash gas formation prior to the expansion valve. Our wire-on-tube and finned-tube condensers are optimized to secure a reliable 3-5K subcooling zone under high-load ambient thresholds.
With global directives phasing out HFCs, our manufacturing processes are adjusted to support natural hydrocarbons and low-GWP alternatives. We utilize oxygen-free copper and high-strength brazing techniques to endure the elevated operating pressures of modern refrigerants.
Unwanted pressure drops inside the condenser tube bundles increase compressor work and degrade system efficiency. By applying computer-simulated loop configurations, we align internal tube diameters to balance velocity profiles with optimal pressure drop limits.
Operating conditions in seaside ports, industrial warehouses, or open residential condenser yards expose copper and steel structures to severe corrosive stress. Ningbo Taojun utilizes high-durability coatings to prevent galvanic oxidation at metal joints.
Refrigeration requirements vary significantly depending on local ambient parameters, structural demands, and regional regulatory codes. Taojun designs and builds custom configurations to perform reliably across diverse settings.
Refrigeration loops in retail environments must operate continuously. Our copper filter driers absorb moisture and process impurities, protecting the compressor motor from damage and securing stable thermal performance in supermarkets.
High humidity and rapid cycle variations in commercial ice makers can introduce moisture into the system. Taojun's copper drying filters utilize 3A molecular sieves, absorbing water vapor to prevent ice blockages in capillary paths.
From heavy-load automotive AC systems to residential heat pumps, compact size and vibration resistance are critical. Our specialized copper fittings and charging valves prevent leaks even when subjected to mechanical vibration in vehicles.
Ningbo Taojun's facility utilizes advanced automated production machinery, integrated ERP scheduling, and an in-house MES (Manufacturing Execution System) deployed to coordinate material flow.
Our raw materials are sourced from reliable mills. Our ITO film is imported directly from Japan, ensuring consistent properties, while our liquid crystal spacer materials feature uniform cell gaps. By importing core equipment from Germany and applying advanced automated testing processes, we achieve a defect rate below 0.05%.
Over our 38-year history, Taojun has evolved from a small regional workshop into an international business partner. Our development milestones highlight our focus on technology, innovation, and customer satisfaction.
