Ningbo Taojun Refrigeration Equipment Co., Ltd. is strategically located in Xiangshan, Ningbo, a highly connected industrial and tourist hub. Founded in 1988, our enterprise trace its engineering heritage to the prestigious Xiangshan Refrigeration Accessories Factory of Zhejiang University.
Over the past three decades, we have evolved from a specialized academic workshop into a massive, multi-tiered manufacturing enterprise integrating design, testing, mass production, and comprehensive global after-sales support. As a certified National High-Tech Enterprise (awarded in 2021), we specialize in the design, optimization, and fabrication of advanced HVAC/R components, including filter driers, condensers, universal fan motors, copper fittings, and refrigeration controls.
Through our premier "Lingshan" and "Taojun" brands, we supply domestic giants such as Haier, Midea, Gree, and Xinfei, while exporting directly to major industrial customers in Europe, North America, South America, and Southeast Asia.




The contemporary heating, ventilation, air conditioning, and refrigeration (HVAC/R) industry is undergoing a structural transition toward energy-efficient, smart systems. At the core of this transition lies the need for highly adaptable, durable universal fan motors. As buildings and commercial industrial systems account for nearly 40% of global energy consumption, optimizing the efficiency of condenser and evaporator fan assemblies has become a regulatory imperative.
Universal fan motors serve as the mechanical backbone of both domestic refrigerators and massive industrial ventilation plants. Because these motors are required to run continuously in challenging environments—exposed to fluctuating temperatures, humidity, and chemical refrigerants—engineers demand component designs that ensure zero leakage, high starting torque, and minimal thermal output.
Partnering with a reliable factory supplier that understands the interplay between the motor, compressor, and refrigeration loop components (such as filter driers and capillary tubes) is critical. Taojun Refrigeration addresses this holistic demand by designing and manufacturing the entire loop structure: from high-precision copper fittings and accumulator systems to high-purity filter driers that protect the compressor and motor circuit from moisture-induced breakdown.
At Taojun Refrigeration, innovation is the ultimate engine of growth. Collaborating directly with doctoral researchers and material scientists from the University of Science and Technology of China (USTC), we have laid down a technical roadmap that addresses the next decade of cooling technology.
Developing brushless DC (BLDC) and EC motors that reduce power input by up to 40% compared to shaded pole counterparts, featuring integrated digital controls for speed variation matching actual cooling demand.
Upgrading filter drier internals and copper piping structures to withstand the higher operating pressures of natural refrigerants like CO2 (R744) and Propane (R290), ensuring clean, moisture-free loops under high operating stress.
Integrating micro-sensors directly within molecular sieves and fan casings to stream real-time saturation and motor temperature data back to host systems, minimizing industrial downtime.

Our core manufacturing and testing systems are imported directly from Germany and Japan. Utilizing computerized MES (Manufacturing Execution Systems), CCD visual inspection, and automated Helium leak testing, we secure consistent physical properties in every batch.
We deploy advanced double-copper manufacturing lines capable of maintaining a ±0.02mm aluminum foil and capillary tube tolerance. Liquid crystal spacers and raw materials are imported from trusted partners in Japan and Europe to avoid thermal decay.
With customized mold workshops, we accommodate private label packaging, physical shape adjustments, and unique electrical configurations. Backed by a flexible production model, we accept starting MOQs of 500 units with swift shipping capabilities.
Whether in extreme regional environments or complex industrial systems, the reliability of our fan motors and refrigeration circuits has been proven globally:
Our 5D Quality System guarantees that every single universal fan motor, drier, and component meets global high-reliability standards:
Environmental Testing: We perform high & low temperature environmental testing (+75°C to -35°C) for 500 continuous hours, alongside thermal shock tests (10°C to 90°C) and damp-heat tests.
Leakage Detection: All refrigeration shells, valves, and joints undergo high-voltage and vacuum dry tests to prevent system leaks. Outgoing products are evaluated via advanced aging lines, securing a final customer satisfaction rating of 98.6%.
We maintain GB/T19001-2016 / ISO9001:2015 certification (Registration No.: 41325Q00065R0S). Our products comply with European RoHS/REACH standards and US UL specifications. Verified by CNCA and Zhongci International.
