In the contemporary thermal management landscape, the 8mm Bundy Tube (double-walled low-carbon steel tubing) serves as the vascular system of global refrigeration. As the world pivots toward more sustainable refrigerants and higher energy efficiency ratings (SEER/EER), the demand for high-integrity, vibration-resistant tubing has reached an all-time high.
Market analysis indicates a robust 6.4% CAGR in the industrial tubing sector, driven by the expansion of cold chain logistics in Southeast Asia and the retrofitting of HVAC systems in the European Union to meet stringent F-Gas regulations. As a global leading 8mm Bundy Tube supplier, Ningbo Taojun Refrigeration Equipment Co., Ltd. is at the forefront of this transition, bridging the gap between traditional metallurgical excellence and modern digital manufacturing.
From household refrigerators to industrial heat exchangers, the 8mm variant offers the optimal balance between fluid flow dynamics and structural heat dissipation capacity.
Our proximity to the world’s leading steel and copper hubs ensures zero-delay sourcing of high-purity low-carbon steel strips and electrolytic copper, vital for the Bundy brazing process.
Utilizing MES (Manufacturing Execution Systems), our factory can pivot from standard 8mm rolls to customized U-bends within 24 hours, maintaining a defect rate below 0.05%.
Located in Ningbo, a global shipping nexus, we provide 72-hour global delivery readiness, ensuring your production lines never experience downtime due to component shortages.
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. The company's leading products include: filter dries, check valves, air conditioning valves, condensers, brass and copper accessories, air conditioning cable ties and other refrigeration accessories series products.
After 30 years of hard work and rapid development, it has now become a comprehensive enterprise integrating the design and development, production and sales, and after-sales service of refrigeration accessories. In 2021, it became a national high-tech enterprise. Our company is committed to technological and process innovation, equipment improvement, and the introduction of advanced management concepts to produce first-class products. Customer satisfaction is our unwavering pursuit. With reasonable design, reliable quality, and perfect after-sales service, the "Lingshan" filter has become a well-known brand in the domestic refrigeration industry.
In 2012, Ningbo Taojun Refrigeration Equipment Co., Ltd. was established, creating the brand "Taojun" condensers, "Taojun" stop valves and other series of products. Over the years, it has established partnerships with well-known domestic and foreign home appliance enterprises such as Haier, Xinfei, Midea, Gree, Whirlpool, Electrolux, and Huarui.
Focused on high-pressure resistance for CO2 (R744) refrigeration systems. Our 8mm Bundy tubes are tested to exceed UL standards for burst pressure, vital for the growing commercial refrigeration market in the US and Canada.
Compliance with RoHS and REACH is paramount. Our PVF-coated (Polyvinyl Fluoride) 8mm tubes provide 1000+ hours of salt spray resistance, ideal for coastal installations in the Mediterranean and North Sea regions.
We are currently researching the integration of thin-film sensors on Bundy tube surfaces to monitor refrigerant temperature and detect micro-leaks in real-time—aligning with the IoT-enabled HVAC trends.
