Many variations of coil construction are available as some are more appropriate for some applications over others. Applications include intake air heating/cooling, process gas heating/cooling, ambient air cooling of oil, water & other process fluids. Some coils are incorporated as components for packaged heating and cooling systems (i.e. radiators, condensers, etc.) Some common construction types include:

Plate-Fin Coils

Consisting of corrugated ‘Plate’ Fins which are easily stacked and are in contact with all of the Tubes in a coil simultaneously. This eliminates separating of the fin from the tube which can make a coil inoperable and unable to transfer heat.

Spiral-Wound Coils

Individual ‘Spiral’ Fins are wrapped around each individual tube from one end of the tube to the other.

L-Foot Finned Coils

Specially fabricated ‘L-Foot’ Fins are assembled onto each tube, increasing ‘surface-to-surface’ contact between the fin and tube.

Welded & Copper-Soldered Fin Coils

Similar to Spiral and L-Foot designs with a welded or soldered bond between the tube and fin. This also eliminates fin-to-tube separation.

Extruded Fin Coils

Dual Tube design where the outer tube is hydraulically extruded to create a pressure bond between tube and fin. The most appropriate coil construction will ensure many trouble-free years of operation.
