View printable literature - SCOTPAK WT3

  • Undesirable, throw-away, non-repairable construction is avoided (as seen on some watertubes and exotic designs)
  • Our FIRETUBE design has 100% water-cooled heat transfer surface; no hot fins to burn away
  • High efficiency is obtained without using a fourth pass; fourth pass tubes have often been subject to premature failure.
  • FIVE square feet of heating surface for each boiler horsepower
  • Time-tested design, 35 years in the field and now with refined features
  • Hinged front doors provide fast access to tubes without disconnection of pipes, fuel lines or electrical cables AND without disturbing firing equipment
  • Shipped completely assembled and factory test-fired
  • Ample steam space and steam release area yield dryer steam and minimize scaling of system components

Excellent Rear Access
  • Separate rear doors offer simpler, faster access
  • An extra 15-inch quick access inspection port is nested in the lower rear door
  • Split rear doors reduce refractory use and attendant maintenance costs
    Refractories are of the field-replaceable, castable variety; no special expensive blocks or bricks
  • Extra handholes are provided in a superior location in the front tube sheet below the furnace
  • Offset handhole plate studs ease insertion and removal

Unique Twin Head Design
  • Two rear tubesheets, one for each pass; uneven stress is eliminated
  • Water-cooled pass divider plate; this prevents short circuiting even if refractory needs repair
  • Twin tube sheets eliminate need for welded tube attachment (welded tubes are more difficult to replace)
  • Large 5/8" BOLTS are used on all doors; fewer are required; opening/closing is faster; easily damaged studs are avoided
  • All fireside doors have long-life gaskets, fit for repeated use
