Engineered for high durability and performance under extreme pressures, perfectly matching Turkey's local standards.
Turkey has positioned itself as the leading manufacturing gateway for heating, ventilation, air conditioning, and refrigeration (HVAC-R) systems serving Europe, North Africa, and the Middle East. With major industrial clusters centered around Istanbul, Izmir, Manisa, and Bursa, Turkish OEMs and system assemblers are facing a steep rise in demand for premium brass accessories, core access valves (Schrader valves), and filtering technologies.
As the European Union moves closer to enforcing stricter F-Gas regulations, the Turkish domestic manufacturing sector is aggressively shifting towards environmentally friendly refrigerants such as R32, R290 (propane), and CO2. These refrigerants function under higher operating pressures and require highly precise manufacturing tolerance standards. Access valves must prevent even the slightest micro-leakage to ensure system longevity, user safety, and environmental compliance.
Taojun Refrigeration partners directly with Turkish distributors and mechanical contractors to provide high-stability access valves with thick copper tails, ensuring seamless brazing with local copper tubing networks.
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. Over the years, we have transitioned from a specialized laboratory accessory workshop into a global production powerhouse.
Our leading products include: filter driers, 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, we are now a comprehensive enterprise integrating design, development, production, sales, and after-sales service. In 2021, Taojun was recognized as a national high-tech enterprise.
With reliable design, certified raw materials, and dedicated technical support, the "Lingshan" filter drier brand has established a stellar reputation across international markets, certified by ISO9001:2008, EU RoHS, and US UL standards.
Specialized manufacturing of copper filter driers, access valves, condensers, and brass copper fittings for domestic and commercial HVAC-R applications.
Our copper filter driers are engineered to protect domestic refrigerators, commercial freezers, and air conditioners from moisture, acids, and solid particles. Built with a robust housing and high-capacity internal desiccants, they ensure the internal chemistry of refrigeration loops remains perfectly balanced.
A summary of our technological edge, strict raw material sourcing, and comprehensive verification processes.
Our core manufacturing facilities and high-precision testing machinery are imported directly from Germany to ensure micro-tolerance dimensional accuracy.
We host 15 engineers in our dedicated R&D center, leveraging strategic technical collaborations with doctors and professors from the University of Science and Technology of China.
Custom tube lengths, variable copper wall thicknesses, and custom brass configurations are available. We tailor-make components to fit local Turkish manufacturing lines.
Our ITO film and high-uniformity liquid crystal spacers are sourced directly from Japan; industrial adhesives from Europe. High heat resistance (80-90°C) ensures system longevity.
Environmental stress-testing under extreme high and low temperatures (75°C to -35°C) for 500 hours, followed by helium mass spectrometer leak detection and thermal shock validation.
Streamlined logistics routes targeting key Turkish entry ports (Ambarli, Izmir, and Mersin) with short customs clearing cycles and flexible payment terms.
In the modern HVAC-R sector, supply chain delays can stall multi-million dollar HVAC installations. To counter this, Taojun has integrated MES (Manufacturing Execution System) intelligent controls and automated logistics platforms across our production facilities. This ensures real-time oversight of materials, from initial copper casting to final testing and dispatch.
Through automation and robotic brazing stations, we maintain low energy usage and high material yields, providing a significant cost advantage to our Turkish partners. By maintaining direct raw material lines and dynamic production buffers, we absorb upstream price spikes, providing stable annual pricing contracts for long-term buyers.
With an annual manufacturing capacity exceeding millions of access valves and filter driers, we fulfill high-volume OEM orders, maintaining an exceptional 99.8% on-time delivery rate.
Over three decades of dedication, growth, and technological innovations in the refrigeration parts industry.
Establishment of our early factory campus, expanding our tooling workshops and domestic sales networks within China.
Implementation of the MES intelligent workshop management system, transitioning to digitized production and precise tracking.
Global logistics expansion, serving over 50 countries with dedicated channels optimized for the Turkish HVAC-R market.
A world brand is supported by a strong corporate culture. We fully understand that our group's core culture is built through Impact, Infiltration, and Integration. Over the past decades, the development of our group has been driven by our four core values: Honesty, Innovation, Responsibility, and Cooperation.
