Explore our precision-engineered core components designed for maximum efficiency and system durability.
Navigating the complexities of modern thermal management with over 35 years of manufacturing excellence.
Ningbo Taojun Refrigeration Equipment Co., Ltd. (formerly Xiangshan Refrigeration Accessories Factory of Zhejiang University, founded in 1988) represents a benchmark of industrial precision. Evolving into a national high-tech enterprise in 2021, we merge academic research depth with mass-manufacturing agility.
Our domestic sales network spans major industrial hubs across China, complemented by deep partnerships with global appliance titans such as Haier, Midea, Gree, Whirlpool, and Electrolux. Our export pipeline reliably delivers to Europe, North and South America, Southeast Asia, and Africa.
Operating under stringent ISO9001:2015 quality frameworks, our product lineup meets rigorous international standards including EU ROHS environmental mandates and US UL certifications, ensuring full regulatory security for global importers.
Deep-dive into the metallurgical, chemical, and precision engineering characteristics that set our components apart.
Our flagship filter driers are engineered using high-purity copper pipes offering extreme resistance to rust and ultra-high internal working pressures. The internal core utilizes precision-packed 3A molecular sieves (achieving water absorption capacities ≥20%) combined with an activated carbon filtration stratum.
| Parameter | Engineering Standard |
|---|---|
| Primary Material | High Purity Deoxidized Copper (DHP) |
| Desiccant Type | 3A Molecular Sieve + Activated Carbon |
| Moisture Absorption | ≥ 20% by weight at standard conditions |
| Welding Method | Controlled Atmosphere Argon Arc Welding |
| Operating Temperature | -35°C to +120°C |
Deploying robust thermal components across diverse microclimates and industrial operational scales.
Widely adopted by home appliance repair networks and OEM factories for household refrigerators and chest freezers. Designed for easy retrofit integration, ensuring prolonged compressor lifespans during major maintenance cycles.
Engineered to handle high-demand commercial refrigeration walk-in coolers, display cabinets, and supermarket multi-compressor racks where continuous uptime and absolute moisture control are paramount.
Integrated into specialized mobile air conditioning circuits and industrial chillers, providing resistance to thermal shock, high vibration loads, and aggressive refrigerant-oil chemical compositions.
Aligning advanced manufacturing with green energy initiatives and next-generation smart factory automation.
As global environmental regulations tighten around low-GWP (Global Warming Potential) refrigerants such as R32, R1234yf, and natural refrigerants (R290, R744), the demand for highly compatible system accessories has escalated. Juntao Refrigeration's R&D center—staffed by 15 leading doctors and professors from the University of Science and Technology of China—is actively spearheading smart production methodologies.
By integrating MES (Manufacturing Execution Systems), automated CCD optical inspection, and helium mass spectrometer leak detection, our roadmap ensures zero-defect manufacturing, full traceability, and sustainable packaging solutions supporting a circular economy.
Expert insights regarding procurement, technical compliance, and custom OEM/ODM manufacturing.
Our filter driers combine a high-purity copper shell with an optimized 3A molecular sieve and activated carbon core. This dual-action mechanism simultaneously traps moisture, removes harmful acids, and filters micro-debris, thereby safeguarding the compressor from premature burnouts and extending operational lifespan by years.
Yes. With over 35 years of engineering expertise and a dedicated R&D center consisting of 15 advanced scientists and engineers, we fully support custom sizes, specific desiccant weights (e.g., 10g, 15g, 20g), unique tube bending configurations, and custom laser-etched branding.
Our operations are fully certified under GB/T19001-2016/ISO9001:2015 quality management standards. Additionally, our products comply with EU ROHS environmental safety directives and carry US UL safety certifications for global market entry.
We maintain flexible manufacturing lines to support both global distributors and major appliance brands. Standard MOQ starts at 500 units for customized components, with rapid global delivery timelines supported by our advanced MES automated workshops.
