  • Fully automatically laser cut and electrically welded steel body
  • Flanged front plate and dished end without T-butt welds to the furnace
  • Flue gas tubes inserted with high temperature steel spiral turbulators
  • High water volume
  • Anti-scale and anti-condensate design
  • Ceramic fibre insulated front door with reversible opening
  • Casing made of easy-to-mount painted steel panels



  • Outer casing with high density insulation
  • Carbon Steel with internal wetted surface polyurethane painted and treated.
  • Complete and standard operational parts are fitted.
  • Maximum operating pressure 5 bar.


Custom designed as per actual requirement is possible; option for stainless steel material is and higher operating pressures were available, pls consult our sales department..



  • Automatically laser cut and electrically welded boiler body constructed from high quality steel SA 516 GR 7.
  • Front tube plate entirely flanged towards the furnace with full penetration face-to-face welding to the furnace (no T-butt weld), ensuring an efficient absorption of furnace expansion and an aerodynamic flue gas profile which eliminates the temperature concentration
  • Furnace back plate fully dished (no T-butt weld) and submerged in the boiler water (wet back design), providing an efficient cooling of the furnace end plate
  • Stay tube welded between the furnace back plate and the rear tube plate for a higher static resistance
  • Dished rear tube plate to absorb the furnace expansion (from model HWT 300)
  • Tubes to front plate unique assembly without projection of the tubes from the plate so as to avoid temperature concentrations
  • Front door manufactured with steel plate and internally insulated with ceramic fibre, mounted on two easy-to-open hinges with reversible opening
  • Rear smoke box manufactured in fireproof thermal insulated steel sheet, bolt mounted, complete with stack connection and cleaning door
  • Radiation surfaces thermally insulated with thick glass wool - outer casing made of easy-to-mount painted steel panels
