Heat Exchanger Coils

As a heat exchanger coil manufacturer, Fin tube, Inc offers various tubing sizes and materials. Our coils can be made in single, double, or multiple-pass configurations to meet your needs. We use an automated coil bending system that produces high-quality bends with excellent repeatability.

We have the equipment and technology to form the tubing in any configuration. We can also provide custom bends with various radii, angles, and lengths.

What is Coils & Bending?

Coils and bending refer to the process of shaping metal tubing into coils, “U” bends, or serpentine shapes. It is a common technique used in the production of heat exchangers. This occurs when coils are formed by wrapping the tubing around a mandrel or using specialized bending machines. “U” bends and serpentine shapes can be produced with an automated machine or manually with a hand bender.

Fin Tube Products, Inc. can produce custom coils, “U” bends, and serpentine shapes with the highest quality. We use advanced machines that can precisely bend tubing to any specification, ensuring accuracy and reliability. Our experts will work with you every step of the way to ensure your heat exchanger design is perfect for your application. 

Applications of Coils & Bending

Coil and bending techniques are used in various applications, most notably heat exchangers. Heat exchanger coils are typically made of copper tubing and transfer heat between two fluids. They can be found in a variety of industries, such as air conditioning, refrigeration,

Our finned tube coil heat exchangers are available in various materials such as carbon steel, stainless steel, copper, aluminum, and other alloys. Fin Tube Products, Inc. offers these services with superior quality assurance standards.

Advantages of using Coils & Bending


Coils and bending offer several advantages when used in coil heat exchanger design. These includes: 

  • The coils are easier to assemble since they require fewer welds, which helps reduce labor costs.
  • They also offer increased heat transfer efficiency due to their high surface area-to-volume ratio, which helps reduce the size of the unit overall.
  • Coils are easier to clean and maintain since they have no sharp corners or edges.
  • Depending on the application requirements, coils can be designed with different tubing sizes and materials.
