The global heating, ventilation, air conditioning, and refrigeration (HVAC/R) industry is undergoing a structural transition driven by decarbonization, strict environmental mandates, and the rising cost of energy. Traditionally, HVAC systems relied on Permanent Split Capacitor (PSC) motors. Today, modern industrial, commercial, and residential networks are phasing out PSC motors in favor of Electronically Commutated Motors (ECM).
Unlike standard induction motors, ECM fan motors utilize a brushless DC architecture combined with a permanent magnet rotor and an integrated microprocessor controller. This dynamic control system allows the motor to automatically adjust its torque and speed to match demand, yielding up to 75% greater operational efficiency. As global carbon reduction frameworks mandate higher Seasonal Energy Efficiency Ratios (SEER) and Energy Efficiency Ratio (EER) targets, global OEMs are prioritizing ECM integration within their core product assemblies.
30+ years of engineered precision and research partnerships with elite institutions.
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 driers, 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, 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. 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.
Leveraging automated assembly, real-time MES data tracking, and uncompromising quality testing.
Our factory incorporates advanced automated winding systems, robotic copper welding arms, and CNC tooling centers imported from Germany. This machinery maintains precise tolerances down to ±0.02mm, ensuring high efficiency in heat exchange components and motor assemblies.
Our Manufacturing Execution System (MES) monitors real-time operations from raw material intake to final system packing. It dynamically handles resource allocation, preventing supply chain disruptions and providing full component batch traceability.
Every production run undergoes strict testing, including helium leak detection, automated visual inspection, and thermal shock cycles from -35°C to 75°C. High-voltage testing up to 100V is performed to identify electrical weak points before packaging.
