The Cleaver-Brooks Modular (MED) Industrial Watertube boiler provides up to 1,050°F superheated steam in a modular unit.


IWT boilers can fire renewable natural gas, biogas and hydrogen. They achieve <2 ppm NOx with an ultra-low NOx burner and SCR equipment, and options are available to increase boiler efficiency by 5% on average.

  • Product Overview
  • Related Resources
  • Applications
  • Modular designs maximize shop assembly and minimize field work.
  • Convection or radiant superheaters.
  • Large, water-cooled, gas-tight furnace areas.
  • Boiler wall constructions are 100% water-cooled and refractory-free.
  • Only single-source supplier for integrated boiler, burner, and control solutions.
  • Can accommodate selective catalytic reduction (SCR) and CO catalyst.


The Modular (MED) is a 100% membrane water-cooled furnace, reducing costly, time-consuming, annual maintenance. The front and rear walls are welded and refractory-free, as well as the burner throat, when integrated with our Natcom® burner. D-style boilers can be customized to provide superheated steam. We offer both single- and dual-stage integral superheater systems with optional temperature control over turndown.
