The application profile

Industrial and service establishments in the food, beverages, textile, building materials, chemicals, ceramics and paper sectors, ... with heat and steam demand, for processing, production and heating.

The design

The company three-pass patent granted in 1952 forms the basis of the outstanding, still today unsurpassed success of this series. The flame tube (1st pass) and two smoke tube banks (2nd and 3rd pass) as well as the wet-back rear reversing chamber are integrated in the boiler body in an ideal arrangement. The laterally positioned flame tube and the horizontal rear- and vertical front heating gas reversal result in the largest possible radiant and convection heat transfer surface with the largest steam space and the smallest external measurements. The flexible ends are firmly anchored by the big, full-length flame tube and joined to the boiler casing by a large, specific number of gusset stays for even load distribution.

Superheated steam is generated by a superheater module. Dimensioned for the required superheating temperature and simply placed on the front reversing chamber. By means of a bypass damper the superheated steam temperature can be kept constant over a wide load range. The smoke tube sections remain freely and easily accessible through the swiveling reversing chamber door.

The high-quality mineral wool mat insulation of the entire boiler body and of the superheater module ensures that radiation losses are negligible. The sturdy base frame reduces the specific ground pressure.
