• Rippled fins produce a rippled air flow pattern for maximum heat transfer. These ripples also assure permanent “fin-tube bond” through greater flexibility under expansion and contraction.

• Staggered tubes create air turbulence to give maximum air side heat transfer.

• Mechanical expansion bond insures permanent metal to metal contact.

• Fin collars are drawn wide and smooth to provide maximum contact area.

• Steam baffle disperses entering steam thereby preventing blow through or short circuiting and ensuring equal steam pressure throughout the supply header.
