Explore our premium grade selection of industrial and domestic refrigeration components engineered to support severe thermodynamic requirements.
Ningbo Taojun Refrigeration Equipment Co., Ltd. is located in the scenic coastal industrial cluster of Xiangshan, Ningbo. Our enterprise began its journey in 1988 as the Xiangshan Refrigeration Accessories Factory of Zhejiang University, leveraging deep academic research and thermodynamic engineering principles.
Over three decades, Taojun has expanded into a global powerhouse, integrating advanced R&D, structural design, manufacturing, and technical support. Today, we stand as a nationally recognized high-tech enterprise, trusted by Tier-1 household and industrial global brands.
Our core product matrix includes premium filter driers, check valves, custom brass/copper fittings, wire tube condensers, and high-efficiency electric cooling fan motors (Aux Fan Motors) configured for diverse environmental requirements.
Our intelligent factory employs real-time MES (Manufacturing Execution System) monitoring, automated assembly, and strict robotic sorting to achieve premium repeatability. The integration of high-purity copper processing, coupled with argon arc welding, eliminates leak risks and extends component lifespans in tough operating settings.
Through our close partnerships with global domestic appliance leaders—including Haier, Xinfei, Midea, Gree, Whirlpool, Electrolux, and Huarui—we deliver certified thermal management solutions designed for commercial food display, domestic cooling, and automotive HVAC setups.
Analyzing the structural shift toward energy-efficient, low-GWP refrigerants and the role of high-performance Aux Fan Motors.
The global transition to Natural Refrigerants (like R290 propane and CO2) requires tighter moisture and acid control. Modern systems need advanced copper filter driers with 3A molecular sieves to prevent moisture-induced freeze-ups and ensure chemical stability across variable pressures.
Modern auxiliary fan motors must deliver maximum aerodynamic efficiency with minimal energy draw. Adapting to EC (Electronically Commutated) architectures lowers parasitic electrical loads in industrial walk-in freezers, directly aiding compliant product designs under ErP directives.
Climate adaptation demands HVAC systems operate reliably in extreme ambient temperatures. Auxiliary cooling components must withstand continuous high thermal loads, relying on advanced insulation, high-temp protective films (resisting up to 90°C), and corrosion-free copper alloys.
From metallurgical optimization to computerized automated inspection systems, we refine every manufacturing phase.
To assure a 10-year service life, we control both raw material quality and assembly steps. Key liquid crystal spacers and ITO films are sourced directly from Japan, ensuring zero-shrinkage uniformity. Our thermal ranges test from -35°C to 75°C, ensuring stability under rapid climate swings.
Our operational trajectory, scaling from a local academic partner to an international high-tech manufacturing facility.
Established as Xiangshan Refrigeration Accessories Factory under Zhejiang University, specializing in early absorption systems and mechanical filters.
Deployed automated shop floor monitoring systems, reducing workflow errors and increasing output capacity for high-volume export lines.
Formally established Ningbo Taojun Refrigeration Equipment Co., Ltd. and introduced the "Taojun" brand of condensers, stop valves, and electrical cooling accessories.
Implemented AI visual inspection algorithms and helium leak testing systems to support zero-defect requirements from overseas partners.
Our solutions adapt to various commercial settings, from residential deep freezers to cold chain transportation lines.
Providing high-durability filter driers and condenser units for household refrigerators, ensuring long-term system stability.
High-efficiency thermal management accessories designed to handle rapid duty cycles in commercial display cases and walk-in chillers.
Providing robust, vibration-resistant auxiliary fans and receiver dryers for mobile cabin cooling and electric vehicle thermal management.
Heavy-duty fluid valves and cooling condensers constructed to handle high pressures under continuous operation.
A global brand relies on a strong corporate culture. We fully understand that culture is formed through Impact, Infiltration, and Integration. The development of our group is guided by four core values:
Our factories conform to global quality directives, guaranteeing compliance for distribution in European and North American markets.
GB/T19001-2016 / ISO9001:2015
Detailed Scope of Certification
Registration No. 41325Q00065R0S
EU RoHS Directive
US UL Safety Certified
Automated manufacturing systems process components cleanly, ensuring low residue levels and particle control in production lines.
Controlled environments and clean assembly zones prevent atmospheric contaminants from affecting internal components before final sealing.
In-house testing labs monitor quality, analyzing structural resilience, burst limits, and desiccant efficiency under stress.
We work closely with global buyers from design phases through to production delivery and field installation.
We offer engineering consulting and fluid simulation support led by dedicated technicians. Hot-line support is available for technical questions and component verification requests.
We perform system reviews and load tests before mass production. Customers receive detailed reliability reports and material analysis records.
All products include a one-year warranty, backed by lifetime technical support and design advice to keep your systems operating reliably.
Addressing common queries from global procurement managers and cooling system designers.
Our copper filter driers feature 3A molecular sieve desiccant cores, providing a water absorption efficiency of ≥20% of their dry weight. This helps control system moisture, preventing acid formation and cap-tube freeze-ups in low-temperature setups.
Yes. We support custom sizing, connector steps, diameter configurations, and specialized bracket designs. Our engineering team can work from your technical blueprints to develop custom cooling components and auxiliary motor brackets.
We combine automated argon-arc welding with CCD inline cameras and helium-vacuum leak detectors to monitor seam quality. This quality control process maintains a leak defect rate of under 0.05% across our products.
Our materials are fully compliant with RoHS and REACH regulations. This clean formulation helps simplify final assembly certification for international markets, including the EU and USA.
