Ningbo Taojun Refrigeration Equipment Co., Ltd. is located in Xiangshan, Ningbo, a beautiful tourist city. Founded in 1988, its predecessor was Xiangshan Refrigeration Accessories Factory of Zhejiang University. Over the past 30 years of hard work, continuous technological iteration, and strategic expansion, our facility has transformed into a comprehensive global enterprise integrating research and development, smart manufacturing, global logistics, and after-sales support.
Recognized as a National High-Tech Enterprise in 2021, Taojun specializes in producing first-class refrigeration components. Our leading portfolio includes advanced copper filter driers, check valves, air conditioning valves, copper-brass fittings, and cable systems. Operating under the renowned "Lingshan" brand, our filtration systems have set industry benchmarks for moisture separation and acid control in refrigeration loops.
Our company has successively passed ISO9001:2008 (updated to GB/T19001-2016 / ISO9001:2015), EU RoHS environmental directives, REACH, and US UL certification. We dedicate ourselves to process and machinery upgrades, utilizing automated lines imported from Germany to guarantee consistent compliance with international safety and performance standards.
Luxembourg, as a pioneering financial and green technology hub in Western Europe, is undergoing an aggressive transition toward energy-efficient, low-carbon building infrastructure. Backed by the Grand Duchy's strict National Integrated Energy and Climate Plan (NECP), the market is heavily phasing out traditional heating systems in favor of high-efficiency heat pumps and centralized district cooling/heating networks.
This green transformation places strict demands on mechanical components. In cities like Luxembourg City, Esch-sur-Alzette, and Differdange, the commercial real estate and datacenter industries require piping systems and filtration components that minimize refrigerant leakage (F-Gas Compliance) and guarantee decades of maintenance-free service.
Our partnership structure in 2012 saw the consolidation of the "Taojun" brand, designing condensers, stop valves, and specialized brass systems for global companies such as Haier, Midea, Whirlpool, Electrolux, and local European installers. We supply critical components that meet these high-efficiency thresholds, ensuring full compliance with European norms.
Addressing the shifting engineering paradigms: F-Gas phasedowns, high-pressure natural refrigerants, and industrial cooling scalability.
We leverage core R&D strength backed by a team of 15 senior engineers and doctoral researchers collaborating with the University of Science and Technology of China (USTC) to solve complex thermodynamics challenges.
Luxembourg enforce strict phase-down of high-GWP refrigerants. Our component metallurgy and safety systems are engineered to withstand the unique pressure curves of eco-friendly alternatives.
We combine massive factory scale with flexible configuration pathways, implementing Manufacturing Execution Systems (MES) to coordinate high-precision production lots.
For over four decades, Taojun has been leading the development and production of refrigeration copper accessories. Our engineering competence rests upon structural superiority and rigorous validation protocols:
A heritage of engineering excellence, starting from research labs to global manufacturing ecosystems.

Luxembourg's F-Gas regulations require systems to minimize potential refrigerant leaks. We manufacture our copper elbows, filter driers, and valves using high-grade copper alloys joined via precise argon arc welding. Each component undergoes automated helium leak detection to guarantee hermetic seal integrity, preventing micro-leakages over long-term operation.
Our production facilities are certified under the ISO 9001:2015 quality management system. Furthermore, all products comply with the European Union's RoHS and REACH directives, confirming they are free of hazardous substances. Our copper tubing and valve assemblies are built to withstand working pressures up to 500 PSI, making them suitable for use with both HFCs and natural refrigerants.
Yes. As an experienced OEM/ODM manufacturer, we can custom-fabricate copper fittings to precise dimensional specifications. Our design engineers work from technical drawing files (DWG/DXF/STEP) to build custom bends and geometries, maintaining tight tolerances (down to ±0.02mm) with minimum order quantities beginning at 500 units per batch.
For standard components, we maintain warehouse inventories to support quick dispatch. Custom manufacturing orders typically require 15 to 25 days for production. Shipping times from Ningbo Port to Europe average 30 to 35 days, and we coordinate with major European freight forwarders to handle customs clearance directly to your local logistics centers.
Our filter driers incorporate 3A molecular sieves that achieve a water absorption rate of ≥20%. By capturing moisture and acids from the refrigerant stream, they prevent ice blockages in expansion valves and reduce copper corrosion inside the compressor motor windings, ensuring the reliability of the system.
