The UNIVERSAL Steam Boiler UL-S from Bosch is engineered with a flame tube, a first and second smoke tube and an internal water-flushed rear flue gas reversing chamber that are structured intelligently within a cylindrical pressure housing. It converts heat from the fuel into steam immediately without material stress because the heat is well distributed while it is transferred.

In case of demanding jobs, the water chamber can be used as a space for storage. The steam bubbles pass through the steam chamber quickly because of its fast heat circulation. This three-pass shell steam boiler is capable of working on medium to high applications.
