Explore our highly specified mechanical fittings, engineered to maximize hermetic seal integrity in high-pressure refrigeration circuits.
Founded in 1988 as the Xiangshan Refrigeration Accessories Factory of Zhejiang University, Ningbo Taojun Refrigeration Equipment Co., Ltd. has evolved into a global titan in thermodynamic system optimization and component manufacturing. Situated in Xiangshan, Ningbo, the company focuses on designing, developing, and manufacturing commercial and residential filter driers, check valves, service valves, condensers, and high-purity copper fittings.
Over the past 30 years, our engineering department has integrated advanced CAD/CAM tooling layouts, automated copper-cutting lines, and robotic brazing stations. Recognition as a National High-Tech Enterprise in 2021 underscored our dedication to metallurgy research, specifically in optimizing refrigerant flow pathways and eliminating moisture in sub-critical refrigeration designs.
Today, our brand represents the zenith of reliability across North America, Europe, South America, and Southeast Asia, engineering systems that satisfy rigorous ISO 9001:2015 standards, RoHS environmental requirements, and UL criteria.
Analyzing shifts in environmental policy, next-gen refrigerant compatibility, and system optimization requirements for B2B procurement officers.
Transitioning toward low-GWP agents like R290 (Propane) and R744 (CO2) demands copper and brass fittings capable of supporting elevated pressures. We optimize structural wall thicknesses and alloy compositions to guarantee performance under challenging thermal cycles.
System failures often derive from copper oxidation. Taojun utilizes premium C12200 phosphorus-deoxidized copper (Cu ≥ 99.90%) to provide protection against stress corrosion cracking and atmospheric degradation over decades of use.
OEMs like Whirlpool, Electrolux, Gree, and Haier depend on predictable lead times. By using digital MES scheduling systems, we balance fluctuating volume demands while maintaining stable pricing despite volatile raw metal index pricing.
Taojun specializes in the manufacturing of filtration, direction, and regulation components for commercial and domestic heat exchangers. Our flagship copper filter driers are engineered to extract acid, system residue, and moisture from circulating refrigerants, safeguarding compressor performance and preserving thermal transfer coefficients.
Additionally, our product range includes high-flow service access valves, custom aluminum roll-bonded evaporators, condenser assemblies, and structural accessories. Whether you require custom dimensions, specialized inlet/outlet connections, or molecular sieve variations, our engineering department delivers tailor-made refrigeration parts designed to meet complex system specifications.
Understand the mechanical parameters, molecular structure, and chemical properties that make Taojun products industry-compliant.
Every copper filter drier we manufacture employs an engineered casing made of high-purity C12200 phosphorus-deoxidized copper. This selection guarantees superior thermal conductivity, ease of brazing, and high structural integrity.
We believe raw quality requires empirical proof. That is why our custom validation laboratory evaluates products under conditions designed to simulate actual HVAC/R field failures:
Over 35 years of engineering progress, from a university-linked workshop to an automated production facility.
Established as Xiangshan Refrigeration Accessories Factory under Zhejiang University, specializing in localized filter design.
Introduced the MES (Manufacturing Execution System) to digitize order tracking, material distribution, and trace quality control data.
Achieved IATF 16949 pre-compliance, upgraded automated cleanrooms, and designed filters compatible with R290/CO2 systems.
A global brand is supported by its corporate culture. At Taojun, we recognize that our principles must guide daily operations through active integration. Our company values rest on four pillars: Honesty, Innovation, Responsibility, and Cooperation.
Honesty: Integrity management and prioritizing quality form the base of our customer relationships. We offer clear material specifications, direct answers, and reliable logistics.
Innovation: Working with academic partners helps us update manufacturing processes and design lighter, more efficient, and robust copper elements.
Responsibility: We follow environmental standards, utilize recyclable cardboard packaging, and aim to reduce emissions during smelting and bending processes.
From domestic freezers to cold storage logistics, our copper and brass fittings ensure stable system operation.
Verifiable certifications proving quality and safety standards for international supply chains.
Ningbo Taojun Refrigeration Equipment Co., Ltd. operates under a verified quality management system. Our official GB/T19001-2016 / ISO9001:2015 standard (Registration Number: 41325Q00065R0S) validates our capabilities in the design, development, and production of filter driers, condensers, and access valves.
This verification is accessible via the National Certification and Accreditation Administration of China (CNCA) portal (www.cnca.gov.cn) and Zhongci International (www.zcgirz.com). For compliance officers, this certificate guarantees that every raw metal batch is tracked and each assembly line follows strict testing procedures.
Furthermore, our components comply with European Union RoHS and REACH directives, confirming they contain no restricted hazardous substances and are safe for residential home appliances.
Underwriter Laboratories approval for high-pressure systems.
Audited processing controls, traceability, and documentation.
Ensures parts are free from heavy metals and toxic chemicals.
How our developmental center is preparing for the future of smart thermal management systems.
We are refining the inner geometry of our copper fittings to minimize fluid turbulence. Reducing pressure drop across filter driers decreases compressor energy consumption by up to 2.5%, matching modern ErP efficiency guidelines.
Our engineers are testing hybrid molecular sieve combinations. By combining zeolite 3A with advanced carbon layers, we aim to capture trace oil degradation byproducts alongside water molecules, extending compressor service life.
We are developing experimental copper filter modules with integrated moisture indicators. These units change color visible through a high-pressure sight glass to alert maintenance teams when the desiccant is saturated, protecting systems from moisture damage.
