Explore our core product lineup of high-performance components designed to withstand rigorous commercial cooling loads and maintain maximum system efficiency.
The global industrial and commercial refrigeration market is undergoing an unprecedented shift. As regulatory frameworks like the Kigali Amendment phase down high-GWP (Global Warming Potential) hydrofluorocarbons (HFCs), engineers are demanding chiller components capable of handling alternative low-GWP synthetics and natural refrigerants (such as CO₂, ammonia, and hydrocarbons like propane R290). This structural shift places extreme demand on micro-components like filter driers, valves, and copper tube fittings.
Moisture, acid, and solid particulate infiltration remain the primary catalysts for compressor failure and heat exchanger degradation. In large-scale water chillers used in hospital HVAC, marine cooling, and district cooling grids, a single system failure can lead to catastrophic operational losses. High-purity copper piping, active desiccant blocks (utilizing 3A molecular sieves), and zero-leakage check valves are the front line of defense in modern cooling systems.
Established in 1988 with roots in the Xiangshan Refrigeration Accessories Factory of Zhejiang University, we combine academic research with advanced industrial scaling.
Ningbo Taojun Refrigeration Equipment Co., Ltd. is located in the coastal manufacturing hub of Xiangshan, Ningbo. Over nearly four decades of rapid development, we have transitioned from a localized factory into a national high-tech enterprise (accredited in 2021) that integrates product R&D, precision manufacturing, international supply chain execution, and comprehensive technical service.
Our flagship "Lingshan" brand filter driers, check valves, and copper accessories have set benchmarks in the Chinese domestic market. We support major global home appliance and industrial cooling brands, including Haier, Xinfei, Midea, Gree, Whirlpool, Electrolux, and Huarui. Our global supply chain network spans Europe, North and South America, Southeast Asia, the Middle East, and Africa.
We are committed to structural and material integrity. Our raw materials—including copper elements and premium adsorbents—are tightly controlled to ensure maximum durability, acid mitigation, and moisture absorption in refrigeration cycles.
Our quality management workflow is validated by internationally recognized regulatory bodies:
A deep dive into our product architecture, metallurgical choices, and performance tolerances.
Our filter driers and accumulator shells utilize deoxidized high-phosphorus copper (C12200), ensuring superior corrosion resistance, high thermal conductivity, and outstanding brazing performance. Engineered to handle burst pressures exceeding 500 PSI, making them compatible with high-pressure refrigerants like R410A.
We incorporate a specialized blend of 3A Molecular Sieve (with a water adsorption capacity ≥20%) and activated alumina. This specific matrix design guarantees targeted water molecule capture without absorbing other bulk refrigerants, while neutralizing harmful acids generated by lubricant breakdown.
Precision joints are welded using inert gas argon-arc technology. Every batch is subjected to pressurized helium mass spectrometer leak detection down to 1x10⁻⁹ mbar·l/s, virtually eliminating micro-fissure leakage during field service life.
Since our inception in 1988 as the Xiangshan Refrigeration Accessories Factory of Zhejiang University, we have maintained a close collaborative pipeline with elite engineering faculties. Today, our centralized R&D center is staffed by 15 full-time research engineers, including PhDs and professors from the University of Science and Technology of China (USTC). This allows Taojun to deploy cutting-edge manufacturing processes, such as MES intelligent workshop systems and advanced CCD visual inspections on our product assembly lines.
Every batch of Taojun refrigeration components is subjected to strict test parameters to ensure decades of reliable deployment in challenging environments.
To maintain our <0.05% defect rate, we enforce a comprehensive testing matrix before any component leaves our Ningbo factory:
Our workshop utilizes automated tube bending machines, precision mechanical stamping lines, and automated desiccant filling systems. This ensures dimensional tolerances are held within ±0.02mm, which is critical for automated OEM assembly lines used by companies like Gree or Carrier.
Over 35 years of engineering breakthroughs in refrigeration and component technology.
We believe that a global brand is only as strong as its underlying values. Our operational approach revolves around four core principles.
We operate with absolute transparency. Integrity in material selection, thickness specifications, and performance testing is the source of our competitive edge.
We continuously innovate our manufacturing processes, adapting to structural shifts in system dynamics and alternative refrigerant chemical profiles.
We maintain a strong sense of mission. Every filter drier and check valve is manufactured to safeguard the life of our client's downstream compressors.
We work alongside OEM engineers to integrate customized dimensions, connection ports, and desiccant capacities for a win-win partnership.
Our components are deployed globally across diverse cooling infrastructure, from domestic home appliances to heavy industrial setups.
Installed inside household refrigerators, upright display freezers, cold rooms, and commercial ice machines. Our molecular sieve driers prevent ice blockages in capillary tubes and thermal expansion valves.
Capable of enduring constant operational vibration and rapid environmental changes. Our heavy-duty copper filter driers and access valves maintain refrigeration loop integrity in transport cooling.
Employed in large-scale chillers for plastic injection molding, medical MRI equipment cooling, data center thermal management, and chemical processing facilities where run-time is critical.
From pre-sales system dimensioning to after-sales supply guarantees, we support international industrial buyers.
Choosing the correct filter drier volume and connection size requires precise calculation. Our sales engineers have extensive experience in HVAC pump and flow dynamics.
We provide technical support throughout the operational lifecycle of our components, ensuring smooth installation and long-term reliability.
Answers to critical questions regarding design tolerances, desiccant saturation, and supply chain management.
