Discover our foundational selection of refrigeration connectors, high-capacity compressors, specialized tubes, and airflow subsystems for commercial cooling lines.
Modern industrial refrigeration networks face unprecedented operational challenges. The transition to eco-friendly, low-GWP refrigerants increases system sensitivity to internal moisture and chemical contaminants, requiring next-generation copper filter driers.
Moisture ingress into sealed HVAC lines forms hydrofluoric and hydrochloric acids upon contact with POE oils. This process leads to motor burnouts, high repair overheads, and system failure. Our molecular sieves absorb active water vapor down to sub-ppm levels.
New-generation refrigerants, such as R32 and carbon dioxide systems, require higher working pressure ratings. Our filter driers feature high-purity spun copper shells with burst pressures designed to exceed standard operating parameters.
Capillary tube blockage due to wax precipitation or metal dust causes component lockup. Our custom internal filter screens are woven with ultra-fine mesh to isolate particulate contamination without compromising refrigerant flow rates.
Ningbo Taojun Refrigeration Equipment Co., Ltd. is located in Xiangshan, Ningbo. Founded in 1988, our predecessor was the Xiangshan Refrigeration Accessories Factory of Zhejiang University. Over 30 years of research and production development, we have grown into a comprehensive enterprise integrating design, manufacturing, sales, and post-sales support for commercial and residential cooling lines.
Under our flagship brand, "Lingshan" filters, and "Taojun" condensers and stop valves, we have become a trusted partner in China's domestic HVAC manufacturing sector. In 2021, Taojun was recognized as a National High-Tech Enterprise, acknowledging our commitment to materials research, structural tooling, and process automation.

We supply components to Tier-1 home appliance manufacturers in domestic and international markets, including Haier, Xinfei, Midea, Gree, Whirlpool, Electrolux, and Huarui. Our product sales networks span Asia, Europe, South America, the Middle East, and Africa.
Our competitive advantage is rooted in precision engineering. From imported manufacturing equipment to raw material validation, we manage every step of the production process.
Our core manufacturing lines are imported from Germany. Key components, such as Japanese high-precision ITO film and liquid crystal spacers, ensure high dimensional accuracy and thermal stability under extreme conditions.
We employ 15 specialized engineers within our dedicated R&D hub, partnering with researchers and professors from the University of Science and Technology of China (USTC) to innovate fluid dynamics and desiccant materials.
We conduct high & low thermal tests (-35°C to 75°C for 500 hours), thermal shock cycles (10°C to 90°C), and continuous damp heat tests. All smart films undergo a 24-hour aging process and high-voltage breakdown tests.
Our copper filter driers are designed to absorb moisture and acid while trapping debris. They are used both as original components and as replacement parts in residential and commercial cooling units.

|---|---|---|---|
| 10g / 15g | 1/4", 3/16", capillary | R134a, R600a, R290 | Domestic Refrigerators, Ice Makers |
| 30g / 50g | 1/4", 3/8", 1/2" | R410A, R404A, R22 | Residential Split Air Conditioning |
| 75g to 150g+ | 1/2", 5/8", 7/8" | R407C, R410A, CO2 | Commercial Chillers, Cold Storage |
Our Zhejiang facility utilizes a MES (Manufacturing Execution System) to monitor manufacturing steps. Real-time visual monitoring using high-definition CCD cameras inspects dimensional tolerances and assembly configurations.
Our components are installed across multiple thermal management sectors, ensuring system longevity and stable heat transfer parameters.
Installed in refrigerators, freezers, and countertop ice makers. Copper filter driers prevent ice blockages in the capillary tubes, protecting the hermetic compressor from moisture and debris.
Used in supermarkets, food storage facilities, and refrigerated trucks. Our multi-directional and bidirectional filter systems help maintain cold chain temperatures and support system reliability.
Designed to handle vibration, thermal cycling, and humidity in mobile air conditioning systems. Engineered for passenger vehicle and light-truck HVAC units.
We maintain international quality certifications to support global market entry and simplify import-export logistics.
Refrigeration systems are shifting toward smart, high-pressure, and eco-friendly designs. We continuously update our products to meet these evolving industry standards.
We are developing smart filter driers with built-in moisture indicators. These allow operators to monitor drying status in real-time, helping prevent unexpected component wear.
Alternative refrigerants like R290 (propane) and R32 require optimized desiccant materials. We are designing new internal configurations to ensure high compatibility with these gases.
To comply with tightening global environmental standards, we are refining our manufacturing lines to produce lead-free copper connectors and accessories.
