Superior Boiler has been granted a U.S. patent for engineering advancements that significantly improve the company’s watertube boiler designs.

Characteristics of the company’s newly patented DFW design include:

  • A smaller overall footprint compared to current designs while maintaining overall capacity throughput.
  • Utilization of a lower fan horsepower to create the same steam flow as a conventional boiler design, resulting in lower overall cost of operations to end users.
  • Lower overall operating emissions, resulting in cleaner overall boiler operating systems that are more environmentally friendly.
  • Reduced requirements for purchased materials and subcomponents.

The DFW system can be applied to all of the company’s existing watertube boilers. It already has been proven out Superior’s O-type (Ottawa) rental trailer units and fixed-location boilers.
