High efficiency fin design
- The High EfficiencyType Fin has been proven in more than 100,000 applications worldwide over a period of more than 50 years
- Inherent advantages include a reduction in overall size and heat transfer surface requirements for a specific cooling duty. Conversely, a similar sized cooling section using the high efficiency fin will require either less air flow thereby reducing power costs or will provide increased cooling capacity. This is an important factor when replacing older tube bundle sections.
- The High Efficiency Fin design offers up to 25% greater heat transfer than the conventional plain fin design. A spiral, L-foot or shoulder-type fin with radial openings achieves superiority over the plain smooth fin by substantially reducing required heat transfer surface while incorporating the strength and non-clogging characteristics of a smooth fin.
Why and How
When any fluid passes over a surface, a stagnant fluid layer or film builds up adjacent to the surface which it is in contact. The greater the contact area and/or longer contact length the greater the stagnant layer becomes. In similar fashion, air passing over a plain or smooth fin surface forms a stagnant air film that reduces thermal conduction and lowers the rate of heat transfer from fin to the atmosphere. The High Efficiency Fin’s interrupted surface through its radial openings, prevents this stagnant film of air from reaching its maximum thickness thus increasing the outside film transfer coefficient. Most importantly, it does not increase the turbulence of the air passing over the fins and the result is an increase in overall heat transfer rate without an increase in static pressure or fan horsepower.
HEADERS
All code headers are constructed of SA516-70N steel utilizing a box type design and incorporating individual hex-head access plugs for easy tube maintenance or replacement in accordance with ASME code. Taper pipe plugs or shoulder access plugs which are spot faced with soft iron gaskets are standard. All tube sheets are built with single or double grooves.

- All sections incorporate a floating header design which allows at least one header to move independently with the expansion and the contraction of the tubes while maintaining proper alignment.
