  1. WAVY fins normally available in aluminum and copper. Flat fins normally available in aluminum, copper, carbon steel and stainless steel.
  2. For coils WITH OTHER THAN CAST HEADERS, other finned widths and increments may be available. For coils WITH CAST HEADERS, it may be possible to use multiple headers and/or coils to produce other finned widths.
  3. Other finned lengths, longer finned lengths and other increments maybe available.

* For modulated steam applications
