Highly calibrated industrial parts deployed across key manufacturing zones in the Bangkok Metropolitan Region.
As the primary economic engine of Thailand, Bangkok serves as the center of Southeast Asia's production corridor. Operating in Samut Prakan, Chonburi, and Rayong (Eastern Economic Corridor - EEC), appliance and automotive manufacturing facilities require highly resilient capacitors, copper piping, and heat exchangers capable of withstanding the local climate. High relative humidity and temperature variations necessitate components manufactured with tight tolerances and premium materials.
Ningbo Taojun Refrigeration Equipment Co., Ltd. supplies high-precision parts configured to function under high electrical stress. Our manufacturing facilities focus on addressing environmental demands to reduce component failure rates in commercial operations.
Founded in 1988, Ningbo Taojun Refrigeration Equipment Co., Ltd. is located in Xiangshan, Ningbo, a tourist destination city. The company’s predecessor was the Xiangshan Refrigeration Accessories Factory of Zhejiang University. Our lead products include: filter driers, check valves, air conditioning valves, condensers, brass and copper accessories, air conditioning cable ties, and related refrigeration series components.
Following 30 years of development, we have established ourselves as a comprehensive enterprise integrating design, R&D, manufacturing, sales, and after-sales service. In 2021, Taojun was recognized as a national high-tech enterprise. By introducing updated management structures and automated equipment, our "Lingshan" filter line has become a recognized brand in domestic and export refrigeration supply chains. We operate under certifications including ISO9001:2008, EU RoHS environmental compliance, and US UL listings.
Our strategic roadmap is aligned with the transition towards decarbonized industrial operations, power stability, and eco-friendly refrigerants.
Operating at high continuous temperatures requires components with excellent thermal dissipation properties. Our capacitors and condensers are manufactured using high-conductivity aluminum alloys and optimized structural geometries, ensuring performance under high thermal loads.
Industrial power grids in expanding industrial zones can experience transient voltage spikes. Our motor capacitor series is designed to handle temporary overvoltages, preventing early dielectric breakdown.
Moisture ingress remains a leading cause of performance degradation in HVAC/R components. We apply argon-arc welding and helium-based leak testing to seal filter driers and valves, ensuring reliable operation over their service life.
Specializing in OEM/ODM fabrication of refrigeration and HVAC parts for over 38 years.
Taojun specializes in refrigeration parts with 38 years of manufacturing expertise. Our products, such as our copper filter driers, are engineered to absorb moisture and acids while trapping system impurities. These are implemented as OEM components and replacement parts in domestic and commercial refrigeration and HVAC systems.
Combining academic research partnerships with industrial manufacturing infrastructure.
Our core production machinery is imported from Germany, ensuring precise dimensioning and high repeatability for heavy-duty HVAC components.
We work with a development team of 15 engineers, including doctoral researchers from the University of Science and Technology of China, to drive product innovation.
We provide full customization for dimensions, shapes, and mounting brackets, allowing direct integration into our customers' manufacturing workflows.
We source ITO films and liquid crystal spacers from Japan to ensure consistency. Our structural adhesives are sourced from European suppliers, selecting materials that withstand operational limits from 70°C to 90°C.
Our testing protocol includes high & low temperature thermal testing (-35°C to 75°C for 500 hours), thermal shock cycles (10°C to 90°C), and damp heat exposure testing for 500 hours. Active components undergo continuous burn-in and high-voltage tests before dispatch.
Located near major shipping ports in Ningbo, we coordinate delivery schedules to Bangkok and surrounding industrial zones, reducing lead times for our partners.
Established in 1988, manufacturing copper filter driers and related HVAC/R components for over 41 years.
Taojun has established domestic R&D and quality control systems for refrigeration components. Since our founding, we have prioritized technical performance and quality assurance as core elements of our market presence.
Our copper filter driers are designed to absorb moisture and system acids, filtering out debris and chemical impurities. They are used as factory components and replacement parts in domestic and commercial refrigeration and freezer systems.

Detailed Certification Scope
Inside our production facilities: precision tooling, stamping, assembly, and testing halls.
Providing component supply to manufacturers in both domestic and export markets.
Our sales network covers industrial centers in China and extends to Europe, the Americas, South America, Southeast Asia, the Middle East, and Africa. We work with our partners to establish reliable component supply chains for commercial and domestic applications.
Technical answers regarding HVAC/R components, logistics, and quality assurance processes.
Our capacitors and electrical components are manufactured with sealed aluminum casings and double-insulated internal layers, protecting them against moisture ingress. This construction helps maintain capacitance stability and electrical insulation in warm, humid environments, such as those found in tropical regions.
Standard production runs require 2 to 4 weeks depending on the order size and custom engineering specifications. Shipping transit from Ningbo Port to Bangkok Port (PAT) generally takes 7 to 10 days, allowing for predictable inventory planning.
Yes, our engineering department provides ODM/OEM services. We fabricate copper and brass components, including U-bends, capillary coils, and filter driers, according to customer-supplied CAD files, ensuring fitment with existing evaporator or condenser layouts.
