Ningbo Taojun Refrigeration Equipment Co., Ltd. is located in Xiangshan, Ningbo, a beautiful coastal city. Founded in 1988, its predecessor was Xiangshan Refrigeration Accessories Factory of Zhejiang University. Over the past 30 years, our company has evolved into a national high-tech enterprise integrating R&D, precision manufacturing, sales, and comprehensive after-sales services.
Our leading brands, including "Lingshan" and "Taojun," represent top-tier refrigeration accessories like copper filter driers, check valves, air conditioning valves, condensers, and brass accessories. By combining our academic roots with industrial scale, we have established long-term strategic partnerships with leading appliance conglomerates globally and within China, including Haier, Midea, Whirlpool, Electrolux, and Gree.
The South Korean HVAC, refrigeration, and electronics manufacturing ecosystems are globally renowned for their strict quality benchmarks, rapid technological transitions, and high sustainability standards. As major Korean industrial OEMs (such as Samsung, LG, and Carrier Korea) accelerate their shift toward eco-friendly refrigerants like R32, R290 (propane), and CO2, the demand for high-integrity, leak-free system components has surged.
Under South Korea's Carbon Neutrality 2050 framework and localized implementation of the Kigali Amendment, refrigeration components must satisfy demanding mechanical properties:
South Korean procurement managers operate under strict Just-In-Time (JIT) delivery guidelines, requiring suppliers to guarantee seamless metallurgical quality and chemical compliance (K-REACH and RoHS). Finding a Tier-1 partner capable of providing custom-extruded copper parts, micro-groove tubes, and certified brazing materials is essential to mitigating supply chain risks.
Years of HVAC/R Expertise
PhD-Led R&D Engineers
Defect Rate Target (5D QA)
Export Countries Worldwide
Our core manufacturing lines employ automated copper cutting, bending, and extrusion systems imported from Germany to guarantee tolerances within ±0.02mm.
Born from the Xiangshan Refrigeration Accessories Factory of Zhejiang University, our 15-engineer R&D team includes PhDs focused on optimizing thermodynamic flow profiles.
Strict testing protocols including high & low temperature aging (-35°C to 75°C for 500h), automated CCD visual inspections, and helium mass spectrometer leak testing.
We provide complete design customization from CAD/SolidWorks prints. Low MOQ (500 units) options allow Korean HVAC startups to scale seamlessly.
Our factory maintains ISO 9001:2015, EU RoHS, REACH, and US UL certifications, ensuring direct conformity with Korea's safety guidelines.
Our Manufacturing Execution System (MES) provides full end-to-end batch traceability, tracking chemical raw materials from formulation to dispatch.
Our core specialization focuses on manufacturing premium filter driers, stop valves, and condensers. The "Lingshan" range is designed to absorb system moisture and acid, preventing critical damage to compressors in commercial refrigeration and domestic heat pumps.
At Taojun, we build reliable relationships with global partners based on our four core principles: Honesty, Innovation, Responsibility, and Cooperation. By aligning our corporate practices with global ESG standards, we ensure that our manufacturing lines minimize environmental impact while maximizing raw material circularity.
Our official quality registration GB/T19001-2016/ISO9001:2015 (Registration No.: 41325Q00065R0S) guarantees strict control over all aspects of designing and producing copper parts, accumulators, and condensers.
We cooperate with overseas inspection organizations to offer regulatory alignment for Korea. This includes offering full documentation for raw material composition, RoHS compliance certificates, and pressure vessel certifications.
Work with an ISO 9001-certified manufacturer to secure consistent material quality, clean brazing connections, and K-REACH-compliant copper supplies.
