Who We Are? — Industry Leadership & Heritage

Founded in 1988, bridging academic research excellence with high-volume industrial manufacturing.

Academic Roots & 30+ Years of Manufacturing Mastery

Ningbo Taojun Refrigeration Equipment Co., Ltd. is located in Xiangshan, Ningbo, a beautiful tourist city. Founded in 1988, its predecessor was 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 and sales, and after-sales service of refrigeration accessories. In 2021, it became 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" and "Taojun" filter lines have become well-known brands in the global refrigeration industry. Certified with ISO9001:2008 / ISO9001:2015 quality management system, EU ROHS environmental protection directive, and US UL certification.

Global Partnerships & Enterprise Trust

Supplying Tier-1 home appliance giants and international refrigeration networks.

In 2012, Ningbo Taojun Refrigeration Equipment Co., Ltd. was established, creating the brand "Taojun" condensers, "Taojun" stop valves and other series of products. Over the years, it has established partnerships with well-known domestic and foreign home appliance enterprises such as Haier, Xinfei, Midea, Gree, Whirlpool, Electrolux, and Huarui.

The product sales network covers major and medium-sized cities in China and is exported to Europe, America, South America, Southeast Asia, the Middle East, Africa and other overseas markets. The company's goal is to support and cooperate with every sincere customer to achieve a win-win situation.

What We Do? — Precision Engineering & Features

Specialized in refrigeration parts for over 38 years with unmatched technical depth.

Filter Driers & Moisture Control

TAOJUN copper filter driers are designed to absorb moisture and acid, and to filter out impurities. Normally installed as a component and replaced as a repair part for both domestic and commercial refrigerators and freezers.

Structure & Premium Materials

Shell: High purity copper pipe (rust resistant, high pressure resistant).
Inner Core: 3A molecular sieve (water absorption ≥20%) + activated carbon layer.
Sealing: Argon arc welding ensuring zero leakage.

Core Operational Strengths

Prolongs equipment lifespan by reducing acid and water corrosion on compressors. Enhances fast cooling efficiency by reducing system resistance and optimizing the refrigerant closed-loop cycle.

Why Choose Us? — Industry 4.0 & Manufacturing Superiority

Industry Whitepaper: Global HVAC Procurement & China Factory 4.0

Navigating modern supply chain resilience, efficiency demands, and localized industrial applications.

1. Global Enterprise HVAC Procurement Dynamics in the Post-Pandemic Era

International OEMs and Tier-1 distributors are increasingly prioritizing supply chain resilience, risk mitigation, and total cost of ownership (TCO) over bare unit price. Modern procurement strategies demand strict traceability, guaranteed material purity (especially for copper tubing and molecular sieve filter driers), and rapid prototyping capabilities. As energy efficiency regulations (such as SEER2 in North America and Ecodesign directives in Europe) tighten, sourcing certified, high-performance HVAC components from established manufacturers has become paramount.

2. China Factory 4.0: Supply Chain Resilience & Smart Manufacturing

Chinese industrial manufacturing has transitioned from labor-intensive assembly to advanced "Factory 4.0" ecosystems. By integrating MES (Manufacturing Execution Systems), automated robotic welding, and automated optical/CCD visual inspection, factories like Ningbo Taojun achieve unprecedented consistency. Helium mass spectrometer leak testing and automated thermal stress screening ensure that every batch of filter driers and access valves meets the rigorous specifications required for modern commercial refrigeration and inverter air conditioning systems.

3. Localized Application Scenarios & Technical Adaptation

HVAC and refrigeration components operate across diverse climatic and operational environments—from tropical domestic refrigerators to heavy-duty commercial cold storage and automotive air conditioning loops. Tailoring desiccant ratios (e.g., specific 3A molecular sieve proportions) prevents moisture freezing in low-temperature circuits, while high-purity copper construction withstands corrosive marine and industrial atmospheres.

Frequently Asked Questions (FAQ)

Expert answers regarding HVAC parts selection, manufacturing standards, and custom procurement.

What is the primary function of a copper filter drier in a refrigeration system?

A copper filter drier is designed to absorb residual moisture and acid, while mechanically filtering out solid particulate impurities from the refrigerant loop. This prevents copper plating on compressor components, expansion valve clogging, and premature mechanical breakdown.

Does Taojun Refrigeration support OEM/ODM customization for global buyers?

Yes. With over 35 years of engineering experience and a dedicated R&D team, we offer comprehensive OEM and ODM services, including customized dimensions, specialized desiccant fill weights (10g, 15g, 20g, etc.), customized port configurations, and private label branding.

What international quality certifications do your HVAC products hold?

Our manufacturing facilities and products are certified under ISO 9001 quality management standards, EU RoHS environmental safety directives, and US UL safety standards, ensuring full compliance for import into North American, European, and global markets.

How do you ensure zero-leakage during the manufacturing of copper fittings and filter driers?

We utilize advanced argon arc welding processes combined with rigorous helium mass spectrometer leak testing on 100% of finished pressure-containing components, guaranteeing absolute hermetic integrity under high operating pressures.
