Explore our high-performance refrigeration parts engineered for maximum moisture adsorption and fluid control efficiency.
Our Legacy in Precision Refrigeration Engineering Since 1988
Ningbo Taojun Refrigeration Equipment Co., Ltd. is strategically situated in Xiangshan, Ningbo, a premier coastal industrial hub. Founded in 1988, the enterprise's foundation originated as the Xiangshan Refrigeration Accessories Factory of Zhejiang University. This foundational integration with elite Chinese academic researchers has defined our technological edge for over three decades.
Our core product portfolio features: Filter Driers, Check Valves, Air Conditioning Valves, Condensers, Brass and Copper Fittings, Air Conditioning Cable Ties, and Custom Receivers. In 2021, Taojun was recognized as a National High-Tech Enterprise, reflecting our continuous investments in manufacturing automation, process design, and material thermodynamics.
Operating under our renowned domestic brand "Lingshan" and our global brand "Taojun", our products serve as crucial components in major cooling networks worldwide. Through long-term partnerships with leading appliance conglomerates—such as Haier, Xinfei, Midea, Gree, Whirlpool, Electrolux, and Huarui—we have established robust distribution channels spanning Europe, North America, South America, Southeast Asia, the Middle East, and Africa.

Inside our high-precision production facilities, engineering design labs, and material testing workshops.
Why OEMs and tier-1 refrigeration buyers depend on our industrial-grade components.
Our core production lines integrate precision automated equipment imported directly from Germany, ensuring precise dimensioning and repeatable weld joints.
Our research unit includes 15 specialist engineers, collaborating with researchers from the University of Science and Technology of China (USTC) to continuously optimize thermodynamic models and flow efficiency.
From high-purity raw copper to imported Japan-grade spacer/films, we monitor each processing step. All parts undergo thermal shock testing (10°C to 90°C), oven desiccant activation, and high-pressure helium leakage verification to ensure robust, leak-free operation.
Why sourcing your filtration hardware from Zhejiang yields significant operational benefits.
Ningbo is globally recognized for its industrial copper processing, smelting, and tube extrusion facilities. By sourcing raw copper and machined components locally, we mitigate domestic transport delays and reduce base material costs, passing these efficiencies directly to our OEM buyers.
Our historical partnership with the engineering labs of Zhejiang University enables us to run computer-modeled fluid dynamics tests. We optimize internal molecular sieve configurations to maximize water and acid adsorption without causing refrigerant pressure drops.
Our location near the Port of Ningbo-Zhoushan—the world's busiest container port—enables flexible, low-cost ocean freight. Standard configurations are dispatched efficiently, and custom design approvals transition smoothly to containerized sea freight.
We accommodate a range of production demands, offering flexible MOQs starting at 500 units for standard sizes. This supports structured inventory management for global distributors and tier-1 assembly factories.
Full compliance with international standards for pressure containment and safety.
Refrigeration systems operate under high internal pressures and contain chemical agents that require strict environmental controls. Ningbo Taojun maintains comprehensive certifications to meet international compliance standards:
ISO 9001 Certificate
Zhongci Quality Scope
UL Certification Proof

How our component series are utilized across various commercial and residential settings.
Protects compressors in home refrigerators and chest freezers from capillary blockage caused by trace water crystallization.
Ensures consistent operation in supermarket display cases, walk-in coolers, and commercial ice machines where moisture limits are strictly monitored.
Heavy-duty copper filters prevent scale and acid accumulation in industrial process chillers, supporting system longevity.
Adapting our manufacturing processes to meet global environmental regulations and design shifts.
The global shift toward natural refrigerants, such as Propane (R290) and Isobutane (R600a), requires high system cleanliness. Because these hydrocarbons are highly miscible with lubricants, filter driers must offer increased water capacity to prevent acid formation and oil breakdown.
Systems using newer eco-friendly blends often operate at higher pressures. Our factory has updated copper wall thickness and automated silver brazing lines to ensure burst test limits exceed 60 bar, maintaining high safety margins.
Modern equipment designs continue to shrink in footprint. We develop custom, multi-port copper drying blocks that integrate liquid receivers and mufflers into a single component, reducing brazing points and leakage risks.
Reliable service and support from technical consulting to post-delivery warranty assistance.
