Explore our leading catalog of high-performance condensers, copper filter driers, receiver tanks, and precision brass fittings designed for domestic, commercial, and industrial HVAC applications.
Ningbo Taojun Refrigeration Equipment Co., Ltd. is located in Xiangshan, Ningbo, a major coastal manufacturing hub. Founded in 1988, our predecessor was the Xiangshan Refrigeration Accessories Factory of Zhejiang University. Over three decades of technology incubation and rigorous production development have transformed us into a leading developer of refrigeration technology.
We are a certified National High-Tech Enterprise specializing in custom OEM/ODM solutions for vapor condensers, molecular sieve copper filter driers, receiver tanks, check valves, and comprehensive brass components. Under our flagship brands, "Lingshan" and "Taojun", we have built trusted relationships with global household appliance giants including Haier, Midea, Gree, Whirlpool, Electrolux, and Huarui.
By blending academic refrigeration research from Zhejiang University with advanced automated production lines, we provide our global clients with first-rate performance safety and supply chain security. Customer satisfaction is our unwavering pursuit. With reasonable design, reliable quality, and perfect after-sales service, we are committed to helping you gain competitive advantage in your local markets.
Adapting to the global transition toward high-efficiency thermodynamic systems and eco-friendly refrigerants.
Our vapor condensers and copper filter driers are specifically engineered to withstand the distinct chemical behaviors and higher operating pressures of low-GWP refrigerants. We conduct rigorous performance tests using R290 (propane), R32, R744 (CO₂), and R600a. Our internal chemistry resists decomposition under high thermal stress, protecting your compressor investments.
Moving beyond standard tube-on-plate designs, our research with the University of Science and Technology of China focuses on maximizing heat transfer coefficients. Utilizing ultra-precise extruded aluminum profiles, we minimize refrigerant charge requirements by up to 40% while enhancing the heat rejection capability, reducing overall equipment footprint.
Our cooling control modules are designed to integrate directly with modern smart thermostats and BMS protocols. Through customized firmware development (OEM/ODM), our systems monitor system pressures, optimize fan speeds, and dynamically mitigate frosting risks in variable-load refrigeration loops.
Serving heavy industry, commercial cold chain logistics, marine cooling, and domestic refrigeration sectors with tailored engineering architectures.
Industrial and commercial operations demand components that can function reliably under severe, non-stop workloads. Taojun's copper filter driers, access valves, and wire tube condensers are constructed to guarantee minimal pressure drops and prevent fluid contamination.
Combining high automation, digital monitoring systems, and strategic coastal logistics to deliver absolute supply security.
Our manufacturing base uses an integrated MES (Manufacturing Execution System) to schedule and monitor our production lines in real-time. This system ensures consistent quality control by tracking materials from raw copper pipe entry to final argon arc welding, minimizing human error and keeping our defect rates below 0.05%.
We invest in advanced machinery imported from Germany, including high-speed wire bending machines, automated tube cutters, and CCD visual inspection systems. The fin pitch tolerances of our condensers are maintained within ±0.02mm, ensuring stable thermal performance and straightforward installation.
Located in Xiangshan, Ningbo, our facility is within short driving distance of Ningbo-Zhoushan Port, the world's busiest container cargo hub. This location gives us direct access to shipping lines, reducing transit times, cutting overland container costs, and helping us manage delivery schedules effectively for our international buyers.
Simplifying B2B compliance processes for smooth integration into North American, European, and Asia-Pacific markets.
Our entire catalog of vapor condensers and copper filter driers fully complies with EU RoHS, REACH, and US UL regulations. We maintain up-to-date certificates, guaranteeing that no restricted heavy metals or toxic chemical compounds enter your cooling loops.
We assist our international clients with customs documentation and tariff classifications. Whether you require FOB Ningbo, CIF destination port, or complete DDP arrangements, our shipping department handles the logistics to prevent port delays.
We provide support across multiple time zones. B2B clients receive direct access to our thermodynamic engineers. We resolve design questions, troubleshoot installation issues, and respond to general inquiries within an 8-hour window.

Key technical details and engineering parameters for evaluating vapor condenser manufacturers.
The quality of copper and aluminum alloys directly impacts system lifespan. Taojun uses copper tubing with purity levels exceeding 99.9% to prevent micro-fissures and leakages under high pressures.
Our raw materials (like liquid crystal spacers and high-purity films) are imported directly from leading suppliers in Japan and Europe to guarantee thermal stability at operating ranges from -35°C to 75°C.
For copper filter driers, moisture and acid absorption are critical metrics. Taojun uses 3A molecular sieves with a water absorption rate ≥20%. This design traps trace moisture and prevents ice blockage and corrosion in the capillary tube.
We use a multi-stage testing procedure to ensure airtight seals on all products. Components undergo automated helium vacuum leak testing, pressure burst tests, and thermal cycle testing.
Our Quality Management System is audited to comply with GB/T19001-2016 and ISO9001:2015 standards, providing full batch traceability for our clients.
Our R&D center, staffed by 15 engineers with academic backgrounds from the University of Science and Technology of China, works directly with clients to design customized condenser profiles and fitting configurations tailored to specific cooling capacities.

Scope of Certification (Filter Driers, Condensers, Valves)
Answering key design, integration, and procurement questions for refrigeration engineers and purchasing managers.
A: Copper filter driers protect the compressor and capillary tube from moisture, acid, and solid contaminants. Taojun uses 3A molecular sieves within high-purity copper shells, providing water absorption capabilities ≥20% and preventing capillary freeze-ups.
A: We use high-purity copper components and argon arc welding. Each condenser is tested using automated high-pressure nitrogen checks followed by helium mass spectrometer leak detection down to 10^-8 mbar.l/s, ensuring long-term system integrity.
A: Yes. We offer comprehensive OEM/ODM customization. Our engineering team, in partnership with Zhejiang University, designs customized length, tube layout, fin pitch, and mounting bracket configurations tailored to your system requirements.
A: Our facility is ISO 9001:2015 certified (Registration No.: 41325Q00065R0S). Our products comply with EU RoHS environmental directives and carry US UL safety markings, facilitating direct import into standard global markets.
