Direct from Ningbo Taojun's advanced manufacturing plant. Globally certified to ISO, UL, and RoHS standards.
Founded in 1988, Ningbo Taojun Refrigeration Equipment Co., Ltd. traces its roots back to the prestigious Xiangshan Refrigeration Accessories Factory of Zhejiang University. Situated in the coastal economic hub of Xiangshan, Ningbo, China, the company has transformed over nearly four decades from a specialized engineering laboratory into a massive, national high-tech manufacturing enterprise. Today, Taojun integrates R&D, precision manufacturing, global distribution, and complete technical services for critical refrigeration components.
Our core product lineup includes state-of-the-art cooler condensers, copper filter driers, check valves, AC stop valves, high-purity brass/copper accessories, and specialized cable assemblies. Under the stewardship of our domestic well-known brand "Lingshan" and our global brand "Taojun", we supply top-tier home appliance giants globally, ensuring reliable performance in millions of cooling cycles every day.
Our technology roadmap prioritizes full structural compatibility with next-generation low-GWP refrigerants (R290, R600a, CO2, and HFO mixtures). This demands optimized internal volumes and enhanced structural burst resistance to manage the specific thermodynamic profiles of natural refrigerants.
Moving toward thinner-wall configurations and microchannel extrusions. This increases heat transfer coefficients by up to 30% while reducing refrigerant charge requirements by up to 40%, aligning perfectly with international environmental regulations and strict corporate green initiatives.
Developing hybrid molecular sieve cartridges equipped with integrated humidity indicators and RFID tracing. This allows real-time health monitoring of commercial systems, warning operators of system leaks or desiccant exhaustion before catastrophic compressor failure occurs.
Step inside our manufacturing hub. Witness the high-speed production line of copper filter driers, advanced brazing processes, and automatic helium leak-detection units working in absolute precision.
Refrigeration components do not work in isolation. Our systems are engineered to address the specific performance demands of major application sectors.
Supplying ultra-clean copper filter driers and micro-condensers for domestic refrigerators and freezers. Partnered with major brands (Haier, Midea, Whirlpool, Electrolux) to secure long-term system integrity with minimum repair rates.
High-capacity double-inflow molecular sieve filter driers and high-duty condensers optimized for supermarkets, display cases, walk-in cold rooms, and refrigerated transport, ensuring temperature consistency and fresh product preservation.
Heavy-duty accumulators, mufflers, copper pipe fittings, and high-performance fan systems designed for multi-split air conditioners, chiller loops, and complex commercial building VRF climate management networks.
Fully Automated Product Line
State-of-the-Art Testing Lab
Ningbo Taojun Refrigeration operates at the forefront of the smart manufacturing transition in China. Our facilities utilize a fully integrated MES (Manufacturing Execution System) intelligent workshop management platform. This digitized structure guarantees complete traceability from raw copper ingots to the finished condenser assembly.
By implementing automatic cutting, high-frequency induction brazing, robotic material handling, and CCD visual inspection, human error is minimized. Our key manufacturing equipment is imported directly from Germany to secure extreme precision in tube drawing, shaping, and assembly.
Our journey from a university-linked workshop to a globally recognized OEM manufacturing partner.
Establishment of our original dedicated manufacturing base, expanding from Xiangshan Refrigeration Accessories Factory of Zhejiang University to address rapidly growing domestic HVAC demands.
Rollout of the first-generation MES intelligent workshop management system, transitioning the plant to structured quality monitoring and optimized cycle-time logistics.
Completion of our automated production complex. Incorporating advanced robotics, environmental laboratories, and reaching peak production capacities for global smart home appliance suppliers.
At Ningbo Taojun, a world-class brand is built on a rock-solid foundation of shared values. We recognize that true corporate culture is forged through Impact, Infiltration, and Integration. Our operational roadmap is sustained by four key pillars:
"Our collaborative engineering approach matches professional talent with specialized customer needs to maximize efficiency."
From micro-electronics cooling to mega cold storages, our components ensure structural safety and thermal exchange efficiency.
We meet strict international standards, enabling smooth product integration across highly regulated regions.
