How modern manufacturing facilities achieve zero-emission thresholds and optimize thermal efficiency through targeted vapor condensation engineering.
In large-scale chemical, pharmaceutical, and refrigeration facilities, venting storage tanks, reactors, and compressor circuits represents a major point of energy loss and potential emissions. A vent condenser serves as a secondary or tertiary heat exchanger designed specifically to capture valuable volatile compounds, refrigerants, and moisture before non-condensable gases are discharged into the atmosphere.
By deploying sub-cooled industrial liquid streams or direct refrigerant expansion inside the shell-and-tube or plate-fin matrices, vent condensers dramatically lower the vapor temperature. This phase change forces contaminants and valuable solvents to drop out as liquid condensates, allowing plants to achieve dual goals: compliance with clean air mandates and resource recovery.
By lowering vent stream temperatures to sub-zero levels, our condensers help chemical processors capture volatile organic compounds (VOCs) and synthetic refrigerants, cutting fugitive emissions by up to 99.2%.
Analyzing standard shifts, cold-chain distribution growth, and raw material optimization across continental borders.
With the strict implementation of European F-Gas regulations and US EPA AIM acts, refrigeration cycles must operate at peak hermetic efficiency. Copper driers, advanced condensators, and valves are critical in ensuring zero refrigerant leaks.
Integrating advanced metallurgical science and mechanical automated processing has positioned China as the global hub for heavy HVAC components. Facilities like Taojun leverage localized raw materials to offer unmatched price-to-performance options.
Transitioning from traditional coils to compact, high-efficiency microchannel layouts allows vent condensers to minimize internal volume while maintaining maximum condensation and heat reject capabilities.
Our history, academic roots, and trajectory from a university accessory shop to a global refrigeration component pioneer.
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. The company's 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, it has now become a comprehensive enterprise integrating the design and development, production, sales, and after-sales service of refrigeration accessories. In 2021, we were officially 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, the "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. The company always takes customer needs as the basis and continuously innovates management concepts to ensure efficient and stable development.
Brand Milestone (2012):
In 2012, Ningbo Taojun Refrigeration Equipment Co., Ltd. was established, creating the brand "Taojun" condensers, "Taojun" stop valves and other series of products. Today, we partner with domestic and global giants including Haier, Xinfei, Midea, Gree, Whirlpool, Electrolux, and Huarui.
Watch Us in Action! Video highlight of our automated manufacturing lines, CNC facilities, and QC processes.
Specialized in refrigeration parts for over 38 years. Our core engineering focuses on maximizing cooling efficiency and eliminating circuit moisture.
Our shells are constructed using high purity copper pipe, providing excellent rust resistance and structural integrity under high working pressures.
We pack our drier units with premium 3A molecular sieves (achieving water absorption rates of ≥20%) combined with activated carbon layers to neutralize acids and capture fine particulate waste.
All copper joints, tube-sheets, and filter connections undergo argon arc welding. This hermetic sealing method completely prevents refrigerant leaks or gas bypasses.
TAOJUN copper filter driers are optimized to absorb moisture and acids, and to filter out system impurities. Typically installed as standard components or replacement parts for both domestic and commercial refrigerators, freezers, and industrial vent condensation systems, they protect core refrigeration compressors from corrosion and blockage.
By actively removing water, moisture, and acid residues, our components minimize copper plating on compressor valves and prevent oxidation of system lubricants, extending system runtime.
Refined hydraulic design reduces internal resistance. Lower system pressure drops improve overall expansion valve efficiency, leading to faster cooling cycles.

Our manufacturing assets, R&D profiles, and standard testing methodologies that support our quality commitment.
Our core manufacturing equipment is imported directly from Germany, ensuring precise machining tolerances down to ±0.02mm for all aluminum and copper forming runs.
We employ 15 engineers in our R&D center, including PhDs and professors from the University of Science and Technology of China (USTC) and Zhejiang University.
Our ITO film (no shrinkage, no color difference) and liquid crystal spacers are sourced from Japan; adhesives are imported from Europe. Protective films resist temperatures from 80-90°C.
Finished products undergo high & low temperature testing at 75°C and -35°C for 500 hours, thermal shock tests from 10°C to 90°C for 30 minutes, and damp heat chamber cycles.
Smart films in sheet form undergo a 24-hour power aging test. Rolled films are tested at 100V high voltage to prevent breakdown before field installation.
We customize sizes, tube counts, connector geometries, and structural shapes. Share your design concepts with us for tailormade HVAC systems.
Our products operate in diverse conditions around the world, from local sub-zero cold chains to tropical climate cooling units.
Industrial facilities require refrigeration accessories engineered for specific climates. In high-ambient tropical zones (such as Southeast Asia and the Middle East), air conditioning condensers must run continuously without high-pressure shutdowns. Taojun condensers use specialized alloy profiles that maximize heat rejection surfaces.
In deep-freeze cold chains across Northern Europe and North America, moisture removal is critical. If water enters the refrigerant stream, it can freeze at the expansion valve, blocking flow. Our high-performance copper filter driers keep moisture limits below critical thresholds, even in low-temperature setups.
High-capacity systems for shopping centers, office complexes, and public transit terminals.
Refrigerated transport, marine shipping containers, and temperature-controlled distribution warehouses.
