Steam boilers

With four different Universal type boiler designs, either as single-flame tube or double-flame tube boiler, we offer a seamless product range to meet any steam requirement.

Bosch steam boilers generate process heat with output ranges from 175 to 55,000 kilograms per hour and are universally applicable. The sizing and equipment level of the products are designed to individual customer specification with many different options and variants available. The result: maximum energy efficiency, excellent conservation of resources and outstanding availability. The intelligent control technology offered by Bosch ensures convenient, fully-automatic boiler operation.
