High-quality components manufactured to stringent global industry standards for reliable performance.
Single-phase fans and their associated motor components serve as the critical mechanical heart for air movement across small-to-medium industrial setups, commercial cold storages, agricultural ventilation facilities, and residential HVAC platforms. In regions where three-phase power grid deployment is restricted, expensive, or impractical, single-phase motors represent the ultimate pathway to reliable heat exchange.
From an aerodynamic standpoint, the reliability of single-phase fan solutions relies heavily on motor stability, capacitor sizing, bearing resilience, and blade profile geometry. Modern commercial systems demand components that not only resist moisture ingress and dust deposition (IP54 to IP68 rating) but also operate with optimized power factors to bypass grid line disturbances.
Ningbo Taojun Refrigeration Equipment Co., Ltd. builds on over 30 years of advanced thermal dynamics expertise to design and supply robust air-conditioning fans, wire tube condensers, and capillary solutions. By maintaining precise rotor dynamics and utilizing premium electromagnetic steel laminations, our single-phase ventilation structures maximize volumetric air discharge while reducing operational acoustic levels.
Our products seamlessly integrate with international compressor lines like Emerson Copeland, Danfoss, Secop, and Tecumseh, providing perfect compatibility for OEM refrigeration builders.
Mapping the transition towards high-performance aerodynamic configurations and energy-compliant architectures.
Across the EU, North America, and parts of Asia, strict carbon-reduction directives (such as the EU's ErP Directive and US DOE motor efficiency thresholds) have transformed cooling components. HVAC manufacturers are forced to move away from inefficient shaded-pole designs. Taojun responds to this market pressure by offering high-efficiency permanent split capacitor (PSC) single-phase motors and integrating lightweight, aerodynamically balanced aluminum fan impellers that maximize cubic feet per minute (CFM) output per watt consumed.
A major failure vector for single-phase cooling assemblies is micro-vibration, which accelerates bearing degradation and generates mechanical noise. Using advanced dynamic balancing equipment imported directly from Germany, every single-phase fan and component produced meets ISO 1940 standard requirements. This strict balance ensures stable operation at rotational speeds up to 3000 RPM, maintaining stable airflow without stressing the copper split service valves or copper lines in air conditioning units.
Industrial applications present harsh operating environments, characterized by high relative humidity, corrosive cleaning agents, and thermal fluctuations. Taojun utilizes high-purity copper and specialized alloy structures across our service valves, accumulators, and Bundy tubes. Additionally, our fan assemblies feature anti-corrosive powder coatings and dual sealed-ball bearings designed for continuous operation at temperature extremes ranging from -35°C to 75°C, boasting an estimated L10 lifetime of 50,000 hours.
Designed for commercial cooling, ventilation systems, and intensive industrial cold storage integrations.

Ningbo Taojun Refrigeration Equipment Co., Ltd. - A Trusted High-Tech Pioneer Since 1988
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, 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.

Specialized in HVAC & Refrigeration Component Manufacturing for Over 38 Years
Taojun is specialized in refrigeration parts for 38 years. Our expertise covers filter driers, access valves, and condensers. Feature: TAOJUN copper filter driers are designed to absorb moisture and acid, and to filter out impurities. They are normally installed as a component and replaced as a repair part for both domestic and commercial refrigerators and freezers.
TAOJUN was established in 1988 and has been producing copper filter driers for 41 years. We have domestic leading research and development ability in refrigeration parts, as well as industry-advanced level in refrigeration parts and quality control abilities. Since we started, Taojun's competitive ability has always been driven by technology.









Engineered to deliver high volumetric air flow and heat dissipation across diverse localized operational settings.
In localized commercial supermarkets and restaurant kitchens, evaporators must function inside sub-zero conditions without ice building up on fan blades. Our dynamically balanced fans run alongside Taojun's copper alloy capillary tubes and double copper filter driers to maintain smooth refrigerant cycles, ensuring uniform temperature distribution across display cases.
Heat dissipation is critical in remote outdoor telecom base stations, which frequently rely on single-phase power lines. Taojun's single-phase fans run continuously to prevent electronic card failures, supported by high-grade condenser structures that withstand continuous outdoor exposure without losing heat transfer efficiency.
Agricultural ventilation requires components that resist dust, humidity, and chemical exposure from fertilizers. Featuring heavy-duty copper split service valves, reliable stop valves, and moisture-resistant fan motors, our setups guarantee reliable operations to keep greenhouse environments regulated.





The cooling technology sector is moving fast toward smart, variable-capacity operations. Over the next five years, Taojun's R&D roadmap focuses on:
1988 - Predecessor factory established as Xiangshan Refrigeration Accessories Factory of Zhejiang University, laying the foundation for our technological edge.
