Engineered for high-efficiency commercial refrigeration and heat pump technologies across Spain's logistics and manufacturing networks.
The Spanish industrial sector is undergoing a profound energy and technological transition. Guided by the EU F-Gas Regulation and Spain's national decarbonization frameworks, domestic OEMs, commercial HVAC contractors, and supermarket distribution chains are rapidly adopting low-GWP refrigerants (R290, CO2, R32). This shift demands high-integrity piping, pressure vessels, and precise mechanical stop valves that prevent refrigerant fugitive emissions.
From processing centers in Andalusia to massive logistics hubs in Zaragoza and Madrid, the structural durability of copper valves and components is vital. Extreme summer temperatures across Spain put immense physical pressure on cooling loops, requiring components built to withstand extreme thermal cycles while maintaining absolute hermetic seal integrity.
Ningbo Taojun Refrigeration Equipment Co., Ltd. is located in Xiangshan, Ningbo. Founded in 1988, its predecessor was the Xiangshan Refrigeration Accessories Factory of Zhejiang University. Over 30 years of hard work and rapid development, we have grown into a comprehensive enterprise integrating the design, development, production, and sales of refrigeration accessories. In 2021, Taojun was officially certified as a National High-Tech Enterprise.
Our core product lineup includes premium filter driers, check valves, air conditioning split service valves, condensers, brass and copper accessories, and tie-wrap lines. By pairing academic R&D with advanced German-imported production tooling, we have achieved long-standing OEM status with world-class home appliance giants such as Haier, Xinfei, Midea, Gree, Whirlpool, Electrolux, and Huarui.




How our refrigeration valves and accessories stand up to strict UNE and European EN guidelines.
Our valve bodies and connection tubes are manufactured with high-purity phosphorus-deoxidized copper (DHP, C12200), ensuring excellent brazing properties, high thermal conductivity, and resistance against dezincification and stress corrosion cracking in humid coastal Mediterranean areas.
TAOJUN copper filter driers feature premium 3A molecular sieve desiccant (water adsorption capacity ≥ 20%) combined with active filtration meshes. This structure prevents capillary tube blockages and protects Spanish compressors from acid and moisture buildup.
All service valves, copper accumulators, and filter driers are sealed using advanced automatic argon arc welding. Each component undergoes automated CCD visual screening and a 100% pressurized helium gas leak detection process, limiting leak rates to less than 0.1 grams per year.
Partnering with us means gaining direct factory pricing without sacrificing engineering pedigree. We have built our manufacturing capacity around heavy capital investments:
High/Low-temperature testing at +75°C and -35°C for 500 consecutive hours.
Rapid temperature transit testing between 10°C and 90°C within 30-minute intervals.
For control elements, 100V high-voltage insulation tests guarantee zero electronic breakdowns.
500-hour environmental humidity exposure to match corrosive Mediterranean marine conditions.
From a local university-affiliated workshop to a world-renowned exporter of critical refrigeration components.
Established as Xiangshan Refrigeration Accessories Factory, acting as a technical translation partner for Zhejiang University's mechanical engineering department.
Deployment of advanced MES (Manufacturing Execution System) workshop management systems, introducing real-time parts barcoding and traceability.
Established Ningbo Taojun Refrigeration Equipment Co., Ltd. and officially launched the brand "Taojun" condensers, stop valves, and copper dryer filters.
Completed global expansion phase. Export networks now cover 50+ countries with active supply nodes across Western and Southern Europe, particularly serving Spain, Italy, and France.
Quality is the cornerstone of industrial HVAC/R safety. Taojun (Ningbo Taojun Refrigeration Equipment Co., Ltd.) is fully certified under GB/T19001-2016 / ISO9001:2015 (Registration No: 41325Q00065R0S) for the design and production of filter driers, condensers, and access valves.
This certification can be verified via China's CNCA system (www.cnca.gov.cn) and our auditing partner, Zhongci International (www.zcgirz.com). Additionally, our products carry full EU RoHS environmental directive certifications and US UL approvals, meeting standard European criteria for commercial project installations.
Our valves and filter driers are designed to withstand high operational pressures, rendering them suitable for:
