In modern HVAC/R systems and automotive thermodynamics, auxiliary fan motors serve as the vital line of defense for heat rejection. In commercial refrigeration, residential air conditioning, and electrical vehicle thermal management, auxiliary cooling fans operate continuously under extreme load variations. As global directives demand higher energy efficiency indices (such as the EU's ErP regulations and US SEER standards), the transition toward Brushless DC (BLDC) and Electronically Commutated (EC) motors is accelerating.
Selecting the best auxiliary fan motor factory is no longer just a purchasing decision—it is a critical engineering partnership. Optimal performance hinges on the mechanical integration between the motor assembly, the refrigeration condenser, and fluid flow dynamics. The integration of high-precision components like copper filter driers and safety valves ensures maximum heat transfer coefficient efficiency and guards against fluid-dynamic stagnation.
ESTABLISHED IN 1988
Located in Xiangshan, Ningbo, Ningbo Taojun Refrigeration Equipment Co., Ltd. was founded in 1988, tracing its roots to the prestigious Xiangshan Refrigeration Accessories Factory of Zhejiang University. Over the past 30 years, the company has transformed into a national high-tech enterprise (accredited in 2021) combining advanced design, comprehensive manufacturing, and global sales channels.
Our core product lineup includes filter driers, check valves, air conditioning split service valves, condensers, brass/copper accessories, and cooling fan motor compatibility components. Under our premier household brand "Lingshan" and our global brand "Taojun", we provide high-reliability refrigeration loops that serve top-tier home appliance brands including Haier, Midea, Gree, Xinfei, Whirlpool, and Electrolux.
By integrating technical innovation, advanced manufacturing systems (MES), and strict quality standards, we continue to fulfill our commitment to zero-defect manufacturing.
Every component is subjected to extensive simulated environments. In our advanced laboratories, we execute high-temp & low-temp testing from -35°C to 75°C for 500 hours, thermal shock trials spanning 10°C to 90°C for 30 minutes, and high-voltage breakdown insulation checks at 100V to ensure complete dielectric integrity. Moisture removal and outgassing are controlled via vacuum baking ovens before shipment.
Core production lines and precision bending machinery are imported directly from Germany, ensuring geometric tolerances within ±0.02mm for aluminum and copper assemblies.
Our designated R&D center is staffed by 15 specialist engineers, including doctors and professors from the University of Science and Technology of China (USTC) specializing in thermodynamics.
Our raw material imports include premium ITO film from Japan and high-performance adhesives from Europe, guaranteeing high thermal reliability and color-stable performance.
The structural layout of auxiliary fan motors and filter driers determines the overall operational lifecycle of HVAC units. Poor filtration leads to moisture ingress, forming acids that dissolve the windings of fan motors and damage compressors.
Shell Material: High-purity, oxygen-free copper tubing resistant to high working pressures (up to 500 PSI/34.5 Bar) and environmental rust.
Inner Core desiccant: 3A molecular sieve with water absorption capacity ≥20% combined with an activated carbon layer to catch acid residues.
Argon Arc Welding: Specialized welding techniques prevent micro-porosities and eliminate gas leakage risks.
China's Yangtze River Delta is the world’s leading hub for refrigeration component supply chains. By establishing factories close to copper processing centers and automated casting facilities, companies can source and deliver components with optimized lead times.
Ningbo Taojun implements a proprietary MES (Manufacturing Execution System) to monitor process parameters in real time. From the arrival of raw material bars to helium mass spectrometer leak testing and final packaging, the production lifecycle is monitored digitally. This enables us to maintain a low minimum order quantity (MOQ) of 500 units and dispatch emergency orders within 72 hours, matching global procurement demands.
Operating continuously in compact enclosures, our fan motors and copper filters (10g, 15g, 20g configurations) prevent moisture condensation and maintain low heat-exchange temperatures.
High capacity refrigeration cycles requiring large-flow filter driers and dynamic auxiliary cooling motors to maintain low temperature ranges in large food storage operations.
High vibration-resistant aux fan setups combined with copper accumulator-mufflers to control noise, vibration, and harshness (NVH) levels inside vehicles.
Originates as Xiangshan Refrigeration Accessories Factory of Zhejiang University. Dedicated to early academic research and thermal accessory development.
Implements the MES intelligent workshop management system, transitioning the facility toward digital product tracking and automated quality checking.
Expands production space and establishes international distribution partnerships across 50 countries, supplying OEM fan parts globally.
We believe in people-oriented integrity management. Building trust with clients is the foundation of our competitive edge.
We continually update our concepts, mechanisms, technology, and management styles to adapt to shifting green energy requirements.
We take active responsibility for our clients' supply chains, ensuring long-term product lifespans and reliable operation.
Ningbo Taojun complies with all major manufacturing and environmental standards. We hold the official GB/T19001-2016 / ISO9001:2015 certification (Registration No.: 41325Q00065R0S) for refrigeration component design and production. Our products also meet the requirements of US UL certification, EU RoHS, and REACH.
