Premium OEM/ODM components engineered for commercial cooling & climate control systems.
Founded in 1988 as the Xiangshan Refrigeration Accessories Factory of Zhejiang University, Ningbo Taojun Refrigeration Equipment Co., Ltd. has spent over three decades evolving into a high-tech powerhouse. Nestled in Xiangshan, Ningbo, the company combines academic research pedigree with cutting-edge industrial execution to supply the global heating, ventilation, air conditioning, and refrigeration (HVAC/R) sectors.
Our comprehensive production facility excels in the research, design, production, and after-sales support of vital refrigeration circuit components, including filter driers, check valves, air conditioning split valves, condensers, brass and copper fittings, and specialized installation accessories. Acknowledged as a National High-Tech Enterprise in 2021, Taojun holds certifications like ISO 9001:2015, EU RoHS, REACH, and US UL certification, ensuring that our products conform strictly to international safety and environmental mandates.
Uncompromising quality and efficient logistics engineered to protect your refrigeration systems.
Our core production machinery and precision testing stations are imported directly from leading technological manufacturers in Germany. Combined with MES intelligent workshop systems, we guarantee high repeatability and zero tolerance for geometric errors.
Operating a state-of-the-art research center staffed by engineering professors and thermodynamic PhDs, we hold dozens of industry patents. We design specialized refrigeration condensers that optimize gas-to-liquid phase transitions under extreme heat loads.
We execute strict high & low temperature thermal cycling (-35°C to 75°C for 500 hours), damp heat exposure, helium mass spectrometer leak testing, and 100V high-voltage aging tests to ensure all smart films and mechanical seals withstand high pressure.
In modern HVAC/R systems, system longevity is dictated by the control of moisture, acid, and solid contaminants. Taojun copper filter driers are explicitly designed to maximize desiccant efficiency by utilizing high-purity copper shells (resistant to structural corrosion and high burst pressures) combined with 3A molecular sieve inner cores. This composition ensures water absorption ≥ 20% while maintaining an activated carbon layer to collect trace organic acids and varnish from the ester oil (POE) or alkylbenzene (AB) lubricants.
A continuous path of engineering evolution, building a global brand on core values of Honesty, Innovation, Responsibility, and Cooperation.
Foundation Year: Xiangshan Refrigeration Accessories Factory of Zhejiang University is established, specializing in heavy-duty commercial filter driers and capillary copper tubing.
Digitalization: Introduction of the MES (Manufacturing Execution System) intelligent workshop management system, securing real-time quality tracing across entire production batches.
Taojun Brand Launch: Establishment of Ningbo Taojun Refrigeration Equipment Co., Ltd., launching the trademarked "Taojun" refrigeration condenser and specialized stop valves line.
Global Automation Integration: Deployment of advanced CCD visual inspection systems, automated helium-leak testing bays, and a deep-tier focus on eco-friendly refrigerant components.
Operating a global supply chain requires strict adherence to localized technical standards and rapid regional service. Ningbo Taojun ensures high quality by offering comprehensive compliance documentation for major regions:
Based in Ningbo, Zhejiang—home to the world's busiest container port—our facility offers substantial logistics advantages. We minimize ocean freight transit and port-clearance delays for global OEMs. Our direct integration with regional copper smelters and local component suppliers guarantees stable pricing, minimizing the impact of raw material market spikes. By utilizing advanced automated high-speed fin presses and tube-bending lines, our production efficiency enables us to support small minimum order quantities (MOQs) and large scale productions.
Enterprise procurement professionals look for suppliers that mitigate transaction risks. Taojun structures its commercial operations around reliable trade terms, utilizing IATF 16949-aligned quality checkpoints. We provide full traceability: material test certificates (MTC) detailing metallurgical composition, helium mass-spectrometer leak test logs, and comprehensive product liability coverage. This level of verification integrates with automated supply chain replenishment systems (such as Kanban or Just-in-Time models) used by international partners like Electrolux and Whirlpool.
The global refrigeration industry is transitioning to low Global Warming Potential (GWP) alternatives such as R32, R290 (propane), R1234yf, and CO₂ (R744). These alternative refrigerants demand higher working pressures and require lubricants that are highly sensitive to moisture. Taojun’s development roadmap features microchannel condensers that reduce refrigerant charge volume by up to 40% while maintaining structural integrity. Our advanced molecular sieve compositions are optimized to prevent chemical breakdown when paired with R32 or R290.
Our comprehensive components list applies across multiple specialized refrigeration sectors:
Using our heavy-duty universal copper filter drier cartridges to eliminate system moisture and organic acids. This prevents freeze-ups at the expansion valve, protecting capillary tubes from internal icing.
Utilizing high-precision copper split service valves, wall-mounted AC outdoor brackets, and charging hose safety valves to secure system charges during residential air conditioning servicing.
Integrating highly resilient aluminum roll-bond evaporators, receiver tanks, and vibration-proof copper accumulator/mufflers to survive structural shocks on mobile cargo systems.
