High-integrity filtration solutions engineered for heat pump systems and commercial refrigeration lines across France.
The refrigeration and heating sector in France is undergoing a profound regulatory transformation driven by the EU F-Gas Regulation (Regulation 2024/573) and the domestic RE2020 environmental regulations. These rules require phasing down high-GWP HFCs and shifting toward natural refrigerants, such as Propane (R290), Isobutane (R600a), CO2 (R744), and HFOs. Because natural refrigerants are highly sensitive to moisture and acid buildup, HVAC/R systems demand specialized, high-durability filter driers to protect compressors and maintain cycle efficiency.
Aluminum filter driers have become critical in this technical shift. Unlike traditional heavy copper driers, aluminum alternatives offer notable weight reduction and prevent galvanic corrosion when integrated with modern aluminum microchannel heat exchangers (MCHX). French commercial refrigeration manufacturers, automotive OEMs, and heat pump producers are increasingly using aluminum filter driers to meet strict lightweighting and efficiency targets.
Ningbo Taojun Refrigeration Equipment Co., Ltd. is located in Xiangshan, Ningbo, a prominent manufacturing hub in China. Founded in 1988, our predecessor was the Xiangshan Refrigeration Accessories Factory of Zhejiang University. Over the past 38 years, we have developed from a specialized university workshop into an advanced enterprise integrating research and development, smart manufacturing, and global sales of premium refrigeration components.
Our core product lineup includes aluminum filter driers, copper filter driers, check valves, air conditioning split service valves, liquid line receivers, and custom copper/brass fittings. In 2021, Taojun was recognized as a National High-Tech Enterprise in China. Our engineering teams work closely with university research centers to improve raw materials and manufacturing methods, helping us deliver reliable, high-performance HVAC/R components to the international market.

In modern industrial sourcing, supplier reliability is just as important as unit pricing. Taojun operates a smart manufacturing facility equipped with advanced MES (Manufacturing Execution System) production management, automated robotic brazing, and real-time visual inspection technologies. This automated infrastructure ensures that every batch of aluminum filter driers exhibits consistent dimensional accuracy and strict weld integrity.
We work with trusted shipping partners to secure key materials, stabilizing costs even during supply chain fluctuations. French refrigeration manufacturers can rely on Taojun for consistent quality, flexible production runs, and containerized logistics solutions delivered directly to European ports like Le Havre and Marseille.
Providing engineering solutions for the commercial food chain, electric vehicle thermal systems, and residential heat pumps.
Our filter driers and liquid receivers protect deep-freeze compressors and food distribution networks from internal system acids and moisture contamination, ensuring reliable performance in French logistics hubs.
As French heating systems transition from fossil fuels to heat pumps, our lightweight aluminum filter driers help manufacturers meet strict packaging and weight limits while maintaining clean operation over the long term.
We work with automotive HVAC suppliers to supply compact, clean-room assembled aluminum driers that match the light weight and reliability required by modern electric vehicle cooling loops.
Verification and compliance systems designed to support quality control teams at European OEMs.
Taojun (Ningbo Taojun Refrigeration Equipment Co., Ltd.) maintains certified quality systems, including GB/T19001-2016 / ISO9001:2015 (Registration No: 41325Q00065R0S). This quality standard covers our design and manufacturing processes for filter driers, condenser assemblies, and access valves.
We perform rigorous physical tests to back up these certifications: 500-hour environmental exposure testing (-35°C to +75°C), high-heat moisture removal cycles, and high-voltage leak scanning. All testing data is archived for customer inspection and compliance verification.

Detailed Scope
From heavy-duty copper split service valves to custom fittings, we supply a wide range of parts for system installations.
Common questions from procurement managers and engineers in the French refrigeration market.
The transition is driven by two main factors: weight reduction and system compatibility. Aluminum filter driers are up to 50% lighter than copper options, which helps lower the overall weight of transport cooling units and heat pump cabinets. In addition, when systems use aluminum microchannel heat exchangers (MCHX), installing aluminum filter driers eliminates copper-to-aluminum joints, reducing the risk of galvanic corrosion.
Our filter driers and related valves are designed to handle low-GWP natural refrigerants like Propane (R290) and CO2 (R744). These refrigerants require moisture-free environments to prevent acid formation. We use high-grade 3A molecular sieves to ensure water adsorption limits and execute helium leak checks to help systems meet the strict leakage prevention guidelines mandated by F-Gas rules.
We use a specialized Zeolite 3A desiccant blend for R290 systems. The 3A pore configuration selectively adsorbs water molecules while leaving the larger refrigerant molecules untouched. This prevents co-adsorption, ensuring the dryer runs cooler and maintains its moisture capture capacity over years of thermal cycling.
We treat our aluminum filter drier bodies with an advanced anodization process. This surface passivation layer prevents oxygen and environmental contaminants from oxidizing the base metal, helping the filter stand up to salt spray, rain, and humidity in coastal French port areas and humid locations.
Our standard manufacturing MOQ is 500 units for custom component configurations, though we can support smaller trial runs for new development programs. Once a designs is finalized, typical factory lead times range from 20 to 30 days. Standard shipping from Ningbo Port to French ports like Marseille or Le Havre adds approximately 30 to 35 days in transit.
Yes, all Taojun copper and aluminum filters, valves, and fittings are compliant with the EU RoHS and REACH environmental directives. Our safety-critical components are also UL-listed, helping OEMs streamline their final system approval steps in international markets.
Yes, we offer full OEM and ODM services. Our engineers can customize the length, diameter, and connection type (solder, thread, flare, or press-fit) to match your system layouts. We also support custom multi-inlet blocks for complicated heat pump flow circuits.
We test our internal filters to ensure they stop particles down to 15 microns. We use high-precision mesh filters and fiberglass pads inside our driers to keep fine molecular sieve dust and pipe installation debris from traveling downstream and clogging expansion valves.
