High-precision systems designed for optimal thermodynamics, system protection, and process efficiency.
As cooling requirements evolve globally, the demand for high-reliability components is surging. Ningbo Taojun Refrigeration Equipment Co., Ltd. (formerly Xiangshan Refrigeration Accessories Factory of Zhejiang University) has been at the forefront of this transformation. Founded in 1988, our team brings over three decades of advanced chemical and electrical engineering expertise directly to modern mechanical cooling applications.
Our structural design leverages thermodynamic modeling and specialized fluid dynamic analysis to manufacture ventilation systems, condensers, and brass accessories with ultra-low thermal resistance. Whether you require ventilation motors for domestic refrigeration systems or heavy-duty access valves for commercial refrigeration, our solutions deliver optimal mechanical execution under demanding conditions.
Engineered to deliver high torque density, low power consumption, and quiet operations across critical applications.
Equipped with automatic reset thermal overload protectors to prevent winding damage under locked-rotor or high-voltage fluctuations, guaranteeing a service life exceeding 10 years.
Wound with 99.9% oxygen-free pure copper wire, reducing electrical losses, boosting power factor, and lowering operational temperatures by up to 15°C.
Double-shielded ball bearings pre-lubricated with high-performance synthetic grease designed for operations spanning -40°C to 120°C, ensuring noise levels under 42 dB.
In forced-convection refrigeration and cooling applications, fan performance dictates overall thermodynamic efficiency. Our single-phase shaded pole and permanent split capacitor (PSC) motors are systematically balanced on computerized dynamic balancing machines. This reduces micro-vibrations that trigger physical stress on piping and refrigerant connections, preventing fatigue-induced micro-leaks.
Our custom shaft lengths and specialized flats enable simple configurations for commercial kitchen exhausts, high-capacity ice makers, display cabinets, and marine cooling plants. By pairing our motor configurations with Taojun’s advanced copper filter driers and access valves, industrial HVAC clients secure a cohesive, unified sub-assembly that minimizes procurement friction.
Operating out of Xiangshan, Ningbo, Taojun enjoys access to one of the world's most robust industrial ecosystems. Our supply chain integrates raw material sourcing directly from certified high-purity copper refineries and specialized stator steel laminate foundries. This regional concentration stabilizes our lead times, shielding international partners from volatile market shifts.
By leveraging Zhejiang’s world-class logistics network and Ningbo Port, we dispatch shipments to North America, Europe, South America, and Southeast Asia quickly. From raw materials, precision extrusion, to automated winding, testing, and final assembly, the entire workflow occurs in-house under strict quality audits.
Refrigeration circuits demand maximum dryness and cleanliness. The presence of even trace moisture can trigger chemical reactions, yielding hydrofluoric or hydrochloric acids that corrode motor windings and cause internal compressor failures.
Our signature copper filter driers feature high-purity copper shells, integrated 3A molecular sieve cores (water absorption capacity ≥20%), and activated carbon filtration. Argon arc welding ensures a completely hermetic seal, protecting refrigeration circuits from contaminants and improving cooling efficiency.
Certified performance and rigorous testing protocols that meet demanding global import regulations.
