Finned Tube Heat Exchanger & Air Cooled Coil Manufacturer
Shanghai Jiangxing is a custom finned tube heat exchanger manufacturer in China, specializing in the design and fabrication of industrial air-cooled heat exchangers and coils for steam, thermal oil, and process fluid applications.
What is a Finned Tube Heat Exchanger?
A finned tube heat exchanger, also known as an air-cooled heat exchanger or an air coil, is designed to transfer heat between a liquid or gas flowing inside tubes and air flowing across the outside. As a manufacturer, Shanghai Jiangxing adds aluminum or copper fins to the tubes to dramatically increase the outer surface area, enabling efficient heat transfer to the air. They are used for both heating and cooling processes.
How do you manufacture finned tube coils?
Our manufacturing process involves expanding tubes into a block of pre-formed fins to create a strong mechanical bond. We use various fin types, including L-fin and embedded fins, and a wide range of tube materials like copper, carbon steel, and stainless steel. The choice of materials depends on the application, balancing thermal performance, corrosion resistance, and cost. Every coil is custom manufactured to specific dimensional and performance requirements.
What are common applications for finned tube coils?
Finned tube heat exchangers are used in a vast array of industrial applications. Common uses include steam coils for industrial dryers and HVAC air handlers, hot water coils for space heating, condenser and evaporator coils for large refrigeration systems, and air-cooled oil coolers for machinery. We manufacture coils for all these applications at our plant in Shanghai, China.
Why choose Shanghai Jiangxing as your manufacturer?
Shanghai Jiangxing is a specialist in custom-built, industrial-grade finned tube heat exchangers. Unlike mass-producers of light-duty coils, we focus on heavy-duty applications requiring robust construction and specific performance. Our engineering team can design a coil to fit your exact dimensional and thermal needs, and as a direct China manufacturer, we offer competitive pricing and flexible lead times. Contact us at jxmike@shheatex.com to start your project.
What are the different types of fins and tubes available?
We manufacture coils with various materials to suit different fluids and environments. Tube materials include copper, aluminum, carbon steel, and stainless steel (304, 316L). Fin materials are typically aluminum for standard applications or copper for better heat transfer or specific environments. For corrosive conditions, we can provide coils with stainless steel tubes and fins, or apply protective coatings.
Frequently asked questions
What information is needed to design a custom finned tube coil?
To design a custom coil, our engineers need the heat load or capacity, details of the fluid inside the tubes (type, flow rate, temperatures), and the entering air temperature and flow rate. We also need the maximum allowable dimensional envelope (height, width, depth) for the coil.
Can you build replacement coils for an existing air handler?
Yes, we specialize in manufacturing dimensionally identical replacement coils. By providing us with the dimensions, connection sizes and locations, and performance data of your existing coil, we can fabricate a new coil that will slide into place with minimal downtime and guaranteed performance.
What is the typical lead time for a custom air coil?
The lead time for a custom manufactured finned tube heat exchanger is generally between 3 to 5 weeks. This can vary based on the size of the coil and the availability of specific materials. We provide a confirmed shipping date once the design is finalized.
Do you ship your finned tube heat exchangers internationally?
Yes, we ship our custom-built coils worldwide from our factory in Shanghai. We construct robust wooden crates to protect the coils and fins during transit and manage all export documentation to ensure a smooth delivery to your site or port of entry.
