Direct supply of precision-engineered fittings, valves, and filtration accessories manufactured under strict ISO quality controls.
Ningbo Taojun Refrigeration Equipment Co., Ltd. is situated in the scenic coastal region of Xiangshan, Ningbo. Established in 1988, our foundations stem from the renowned Xiangshan Refrigeration Accessories Factory of Zhejiang University. Over more than three decades of relentless refinement, we have progressed from a specialized design workshop into a unified industrial corporation coordinating structural development, precision production, global sales, and direct client care for core HVAC/R accessories.
Recognized officially as a National High-Tech Enterprise in 2021, Taojun focuses on structural integration, technological modernization, and implementing progressive management frameworks. Our prominent catalog contains professional-grade filter driers, check valves, air conditioning valves, copper & brass fittings, accumulators, and premium insulating wraps. With reasonable architectural design, reliable quality controls, and a dedicated response system, our flagship brand "Lingshan" has established itself as an authoritative standard in China's domestic HVAC industry.
Our quality policies conform to stringent international frameworks, evidenced by our successful compliance audits under ISO9001:2015, compliance with the European Union RoHS Directives, and certifications from Underwriters Laboratories (UL).
Since establishing Ningbo Taojun Refrigeration Equipment Co., Ltd. as a unified brand in 2012, we have expanded our design and engineering reach. We have forged long-term, high-level cooperative relationships with elite household appliance corporations globally, including Haier, Xinfei, Midea, Gree, Whirlpool, Electrolux, and Huarui.
Our extensive supply grid routes seamlessly to large and mid-sized industrial centers throughout China, alongside consistent exports to regions across Europe, North and South America, Southeast Asia, the Middle East, and Africa. By combining technological advancements with client-first values, we provide the global supply chain with stability, technical expertise, and reliable performance.
Unlocking information gains for international buyers through localized scale, material excellence, and technical innovation.
Ningbo is a key global manufacturing hub for HVAC/R components. Our factory utilizes local copper refining networks and automated tube extrusion mills to keep raw material costs low. This proximity allows us to secure 99.9% pure C12200 copper alloy quickly, ensuring short lead times and stable pricing.
With R410A transitioning to eco-friendly but flammable and high-pressure alternatives like R32, R290 (propane), and R744 (CO2), ACR systems demand specialized tubing. Our factory engineers high-pressure resistant walls and helium leak-tested fittings to prevent dangerous gas escapes under high operational loads.
We ease supply chain pressure by offering end-to-end trace documentation. Every batch of extruded copper pipes or CNC-machined connectors is shipped with Mill Test Certificates (MTC), chemical purity assurances, and stress testing logs, satisfying standard regulatory requirements in Europe, America, and beyond.
Taojun's products serve critical functions across diverse application spaces:
Ensuring structural reliability through computerized assembly, high-precision tooling, and strict testing protocols.
Our core production is backed by research and development, utilizing raw materials and strict quality checkups:
Shell Material: High-purity copper pipe (rust-resistant, high pressure-resistant, designed to survive critical structural stresses).
Inner Core: High-activity 3A molecular sieve (water absorption efficiency ≥ 20%) combined with active carbon barriers to stop sludge, acid, and foreign materials from accessing vital components.
Sealing Integrity: Micro-gap orbital gas tungsten arc welding (TIG/Argon Arc) ensures seamless closures without thermal scaling inside the line.
Rigorous Testing Protocols: Every batch is subjected to high and low-temperature cycling (-35°C to 75°C for 500 hours), thermal shock profiles (10°C to 90°C for 30 minutes), and 24-hour electrical aging on smart electronic parts. This guarantees high reliability across global climate zones.
