Ningbo Taojun Refrigeration Equipment Co., Ltd. is located in Xiangshan, Ningbo, a beautiful tourist city. Founded in 1988, its predecessor was the Xiangshan Refrigeration Accessories Factory of Zhejiang University. Following over 30 years of hard work and rapid development, it has now become a comprehensive enterprise integrating the design, development, production, sales, and after-sales service of premium refrigeration accessories. In 2021, Taojun was recognized as 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, our "Lingshan" filter has become a well-known brand in the domestic refrigeration industry. The company has successively passed ISO9001:2008 quality management system certification, EU ROHS environmental protection directive certification, and US UL certification.
In 2012, Ningbo Taojun Refrigeration Equipment Co., Ltd. was established, creating the brand "Taojun" condensers, "Taojun" stop valves, and other refrigeration accessory series. Over the years, we have established deep, mutually beneficial partnerships with well-known domestic and foreign home appliance enterprises, including Haier, Xinfei, Midea, Gree, Whirlpool, Electrolux, and Huarui.
Our extensive sales network covers major and medium-sized cities in China and is exported globally to Europe, America, South America, Southeast Asia, the Middle East, and Africa. We seek to support and cooperate with every sincere customer to achieve a win-win situation.
Deep-dive whitepaper analysis on materials, absorption dynamics, and system protection.
Moisture is the primary enemy of efficient refrigeration loops. In modern systems, trace levels of water react under high operating pressures and temperatures to form corrosive acids. These acids attack copper winders in hermetic compressors, causing chemical breakdown and motor failure. Additionally, ice crystals formed by free water can physically block capillary tubes and expansion valves, resulting in total system failure.
An aluminum filter drier acts as a physical filter and chemical purifier. By utilizing a high-purity aluminum shell combined with advanced molecular sieve technology, it absorbs moisture, captures residual acids, and filters out particulate debris.
Pioneering innovation through German machinery, academic collaboration, and rigorous testing protocols.
We host 15 engineers in our R&D center, consisting of doctors and professors from the University of Science and Technology of China (USTC). This academic foundation fuels our innovation in thermal dynamics and fluid mechanics.
Our core production and extrusion machinery is imported directly from Germany, enabling high-precision manufacturing tolerances. Automation ensures consistent wall thickness and uniform desiccant volume.
We source raw materials globally. Our high-grade Japanese ITO film (no shrinkage, zero color difference) and liquid crystal spacers are imported directly. We run thermal and mechanical stress tests on all components.
Our finished products undergo a thermal shock test from 10°C to 90°C for 30 minutes, followed by vacuum oven moisture removal. Smart films in sheets undergo a 24-hour aging process, and rolls are checked with 100V high voltage to guarantee zero breakdown.
How Ningbo Taojun integrates local material ecosystems with world-class logistics to serve global OEMs.
Our strategic location in Xiangshan, Ningbo, connects our facility to the world's busiest container port. This provides logistics advantages, reducing transit times and port costs. Additionally, Zhejiang's industrial cluster grants us direct access to high-purity aluminum smelters and copper tube manufacturers, keeping our material costs highly competitive.
Through our MES (Manufacturing Execution System) intelligent workshop management system, established in 2008 and updated in 2024, we optimize inventory levels and monitor real-time production flow to prevent delays. This enables us to maintain a low lead time, even for high-volume custom orders.
We understand that global buyers require compliance documentation, supply security, and customized product designs. Whether you need custom inlet/outlet diameters for air conditioners or dual-source desiccant mixtures for commercial chest freezers, we deliver tailored designs to meet your requirements.
Engineered for high performance across diverse domestic, commercial, and automotive refrigeration platforms.
Our line of filters and accessories is compatible with multiple refrigerants, including standard HFCs like R134a, natural HC alternatives like R600a and R290, and high-pressure blends like R410A.
