The steam boiler type UL-S is a three-pass shell boiler and fulfils all the requirements in the medium to high output ranges.

Intuitive PLC-based boiler control with very high operating data transparency
High level of efficiency due to three-pass technology, integrated economizer and effective thermally insulating materials
High level of pressure consistency and steam quality even with widely fluctuating steam demand
The boiler can be equipped with a separate fourth pass in order to exploit waste heat
The boiler body can also be used as a pure waste heat boiler downstream of combined heat and power units or gas turbines
SUC automatic start-up, standby and shutdown control
Suitable for all burner systems
Pollutant reduced combustion thanks to the use of highly developed firing systems and careful selection of the best boiler and burner combination
Easy commissioning with pre-parameterised boiler control
