Cylindrical Heaters

Cylindrical Heaters

These heaters can have either helical coils or serpentine coils depending on your specific requirements and most suitable design solution to meet them.

Helical coils are self-draining with lower pressure drop, but they are limited by the number of flow passes and are more expensive to fabricate. Heaters of this type represent a low cost design which requires a minimum of plot area. Typical duties are 0.5 to 20 million Btu/h.

Serpentine coils are easier to maintain and less expensive to build. Here the tube coil is placed vertically along the walls of the combustion chamber. Heaters of this type also represent a low cost design which requires a minimum of plot area. Typical duties are 0.5 to 20 million Btu/h.

Cylindrical heaters having a serpentine coil with cross-flow convection provides an economical, high-efficiency design that requires a minimum of plot area. The majority of heater installations fall into this category. Typical duty range is 10 to 200 million Btu/h.

 

 

 

Among Helical and Serpentine (vertical) coil heaters, the following types exist:

  • Helical Coil
  • Vertical Coil
  • Twin Vertical Coil
  • Segmented Vertical Coil

The type of heater offered is carefully selected to feature low capital cost, high efficiency, close control and trouble free operation. We will consider all of your requirements, and make recommendations based on our experience for the most suitable design.
