Explore our premium product portfolio designed for high efficiency, operational longevity, and seamless integration into commercial and domestic HVAC systems.
Founded in 1988 as the predecessor Xiangshan Refrigeration Accessories Factory of Zhejiang University, Ningbo Taojun Refrigeration Equipment Co., Ltd. is strategically situated in Xiangshan, Ningbo. Over more than three decades of specialized development, we have evolved into a national high-tech enterprise (awarded in 2021) integrating refrigeration parts design, technological research and development, smart manufacturing, and customer service.
Our comprehensive production facility excels in creating world-class components including filter driers, check valves, AC service valves, condensers, brass and copper fittings, and advanced thermal system accessories. Through strict engineering precision, we have earned a formidable reputation under the domestic trademark "Lingshan" and our global brand "Taojun". Our operational values prioritize customer satisfaction, system reliability, and advanced technology.
In modern industrial and commercial refrigeration, the auxiliary fan motor serves as the vital heartbeat of forced-convection cooling systems. Unpack how our components integrate into micro and macro cooling networks.
Auxiliary fan motors actively regulate condenser head pressure. In high-ambient temperature regions, standard natural convection is insufficient, resulting in compressed refrigerant gaseous back-pressure. Our high-airflow fan motors ensure continuous convective heat transfer, preventing thermal overload of compressors.
Commercial refrigeration systems operated in urban environments face strict noise regulations. Utilizing advanced rotor dynamics, Japanese-grade liquid crystal spacers, and dynamically balanced fan blades, Taojun aux fan motors operate below 42dB while maintaining high static pressure outputs.
By coordinating fan speed with condenser thermodynamic requirements, energy expenditure drops by up to 22%. Integrated with our high-purity copper filter driers and microchannel condensers, our auxiliary cooling fans minimize system pressure drop, enabling peak efficiency.
The global demand for reliable cooling solutions has surged, fueled by the expansion of cold chains, high-performance HVAC platforms, and industrial control cabinets. Today, leading brands require suppliers who offer more than generic assemblies; they need engineering partnerships that mitigate system downtime.
Currently, the market faces significant hurdles including low-grade aluminum windings that corrode prematurely, high acoustic resonance in multi-fan installations, and standard bearing failures due to thermal shock. Taojun address these issues by combining localized material control with stringent compliance systems, maintaining direct supply networks for leading appliance makers such as Haier, Xinfei, Midea, Gree, Whirlpool, Electrolux, and Huarui.
Quality control at Ningbo Taojun is integrated directly into our product development cycle, starting with premium raw materials and extending to automated German production machinery.
We source our core raw materials globally to ensure extreme performance. Our ITO films (ensuring zero shrinkage and absolute color consistency) and liquid crystal spacers are directly imported from Japan. Our engineering adhesives are procured from European chemical providers to withstand operating ranges exceeding 70°C, with protective films resisting high temperatures of 80-90°C.
To reduce human assembly tolerances, we utilize high-precision German manufacturing equipment. Every copper filter drier casing uses high-purity copper pipes, which are rust-proof and high-pressure resistant. The internal molecular sieves comprise premium 3A desiccant (water absorption capacity ≥20%) combined with active carbon, sealed using precise argon arc welding techniques.
Every batch undergoes thermal shock testing between 10°C and 90°C for 30 minutes, damp heat testing for 500 hours, and high/low temperature tests at 75°C and -35°C for 500 hours. Our smart sheet films undergo 24-hour continuous load aging, while our film rolls are subjected to a 100V high-voltage insulation check to ensure zero breakdowns.
Our thermal components and fan units are optimized for several application scenarios globally, ensuring maximum performance regardless of environmental extremes.
Custom-sized copper filter driers and micro aux fan motors maintain steady coolant states in home refrigerators and freezers, operating silently behind the scenes for years.
Heavy-duty condensers and auxiliary fans operating in distribution depots prevent high heat loads from causing cooling loop drops during active door cycling.
Vibration-resistant bracket arrays combined with low-vibration aux fans provide consistent temperature control inside modern vehicle cabins, even in off-road environments.
At Taojun, our engineering vision looks toward the future. In collaboration with R&D experts from the University of Science and Technology of China (USTC), we are developing smart, networked cooling components designed for tomorrow's green energy grids.
Operating internationally requires strict compliance with diverse regulatory and quality standards. Our business processes are fully certified to ensure reliable delivery to any continent.
