Founded in 1988 as the Xiangshan Refrigeration Accessories Factory of Zhejiang University, Ningbo Taojun Refrigeration Equipment Co., Ltd. has developed into a premier powerhouse in thermodynamic research and auxiliary component fabrication. Today, we sit at the intersection of thermal research and scalable production, providing components that satisfy the demanding needs of global refrigeration systems.
Our modern industrial campus in Xiangshan, Ningbo, utilizes advanced manufacturing systems. Certified as a National High-Tech Enterprise in 2021, Taojun represents quality, continuity, and compliance. We produce copper condensers, filter driers, check valves, air conditioning valves, and brass/copper connectors that keep domestic and commercial cooling infrastructure running reliably.
We work closely with major domestic and international brands, including Haier, Midea, Gree, Whirlpool, Electrolux, and Huarui. These partnerships validate our engineering precision and our commitment to quality across global supply chains.
Analysis of thermodynamic requirements, green refrigerant compliance, and supply chain security for modern procurement organizations.
The global shift toward Hydrofluoroolefins (HFOs) and natural refrigerants (R290, R600a, CO2) requires components designed for higher operating pressures and chemical compatibility. Taojun's copper systems are engineered to prevent leakage and support systems using modern eco-friendly refrigerants.
Modern HVAC units demand smaller, highly efficient heat exchangers. Achieving these compact profiles requires clean internal copper surfaces, precise tube-bending geometries, and optimization for low pressure drops to improve overall system efficiency.
Global supply chains require clear documentation. Manufacturing partners must supply certified metallurgical analyses and confirm compliance with RoHS, REACH, and safety standards like UL, ensuring components are ready for regulatory audits.
The efficiency of a copper condenser depends on material purity and clean internal pathways. Impurities reduce thermal conductivity, while moisture inside the lines can cause ice blockages, acid buildup, and premature compressor wear.
Constructed from high-grade copper pipe to provide high thermal transfer, oxidation resistance, and the strength needed to handle high-pressure refrigerants.
Selected to selectively absorb moisture without capturing the refrigerant or its lubricants. Water absorption capacity meets or exceeds 20% by weight.
Welding is performed under controlled atmospheres to eliminate oxidation, ensuring clean joints that prevent refrigerant leaks under high pressures.
How we combine research from the University of Science and Technology of China with German production technology to achieve a 0.05% defect rate.
Our core production machinery is imported directly from German engineering providers, enabling tight tolerances and consistent dimensional accuracy across large wholesale production runs.
Our research and development team includes 15 engineers with backgrounds from the University of Science and Technology of China, specializing in thermodynamic simulation and material science.
Raw materials are sourced from qualified partners, with key components like ITO film and liquid crystal spacers imported from Japan. Our testing protocols include 500-hour environmental chamber testing, thermal shock, and helium leak testing.
From a specialized university workshop, Ningbo Taojun has grown into a high-tech manufacturing partner for the HVAC and refrigeration industries.
Established as Xiangshan Refrigeration Accessories Factory of Zhejiang University, laying the groundwork for our technical standards.
Expanded physical operations and modernized tooling systems to serve domestic air conditioning manufacturers.
Implemented MES (Manufacturing Execution System) intelligent workshops, introducing real-time quality tracking and shop floor visibility.
Established Ningbo Taojun Refrigeration Equipment Co., Ltd. and launched the brand "Taojun" for condensers and valves.
Recognized as a National High-Tech Enterprise and achieved ISO 9001:2015 certification for our quality management system.
We work with clients based on clear documentation, verified material grades, and transparent production timelines.
Our engineering teams focus on improving the thermal and structural performance of our components.
We provide long-term component support and stand behind our products with comprehensive warranty coverage.
Our logistical network and compliance teams simplify global sourcing for partners in Europe, the Americas, and Asia.
Taojun products meet the regulatory requirements of international target markets, simplifying import processes and integration into final equipment.
Registration Number: 41325Q00065R0S - Scope: Design and manufacturing of refrigeration components (filter driers, condensers, access valves). Verifiable on the CNCA database (www.cnca.gov.cn).
We support our partners at every stage of the project, from design consulting to post-installation service.
Direct communication with sales engineers with at least 15 years of industry experience.
Custom component geometry design, mechanical drafting, and simulation modeling.
Dedicated technical support desk responding to design inquiries within 8 hours.
One-year full product warranty, backed by engineering support for the life of the system.
Installation guidance, debugging assistance, and troubleshooting for integration issues.
Regular review of component performance in the field to support continuous quality improvements.
Answers to key technical and operational questions frequently raised by commercial refrigeration and HVAC procurement teams.
We use high-purity C12200 phosphorus-deoxidized copper with a minimum copper content of 99.9%. This helps maintain thermal conductivity (approximately 401 W/m·K) and structural integrity under high pressure, while preventing internal corrosion and pinhole leaks.
We use high-capacity 3A molecular sieves that absorb water molecules while leaving refrigerant molecules untouched. This prevents hydrolysis and the formation of hydrochloric or hydrofluoric acids, protecting the compressor motor winding insulation.
Yes, our engineering center provides full OEM and ODM services. We design custom tube diameters, bending radii, connection interfaces, and body lengths to fit specific system layouts, working with a minimum order quantity (MOQ) of 500 units.
Every batch goes through helium mass spectrometer leak detection. We subject parts to thermal shock testing between -35°C and 75°C for 500 hours, followed by high-voltage insulation tests up to 100V for components with electrical parts, ensuring zero physical breakdown.
Standard product orders are typically processed and shipped within 15 to 30 days. For urgent global projects, our location near major Ningbo port facilities allows us to arrange rapid customs clearance and coordinate shipping schedules to meet tight project deadlines.
Yes. All of our refrigeration accessories, including filter driers, stop valves, and copper connectors, fully comply with EU RoHS, REACH directives, and US UL standards, ensuring safe import and distribution in western markets.
