Bare Tube Coils

Bare Tube Coils


Bare tube coils are coils that have tubes only without fins. Fins provide most of the heat transfer area and are responsible for most of a coils capacity. However, the problem with fins is that they can get blocked with particulate in the air stream, which is problematic for coils that have a tights fin spacing below 8 fins per inch. Restricting the air flow will lead to a reduction in the coil capacity and will affect the entire process, which is why it’s recommended to use bare tube coils. Bare tube coils are commonly used in high-temperature applications where there are particulates in the airstream because the build-up of a product becomes a fire hazard. Advanced Coil’s bare coil tubes are manufactured using a specialized tube blender that allows for faster production. Also, our tube coils can be designed and built to meet ASME Boiler and Pressure Vessel Code, Section VIII, Division 1, U-stamp, and when requested all of our offerings can be National Board registered or CRN registered.
