The UNIVERSAL steam boiler ZFR is a shell boiler in three-pass technology with two flame tubes and completely separate smoke gas passages. It is to be found wherever a reliable steam and heat supply with high output is required. The economizer and superheater can be upgraded in simple modular construction. The dimensions of the flame tubes, smoke tube bundles, water chamber and steam chamber have optimum thermodynamics. Radiant and convection heating surfaces generate a special dynamic in conjunction with the possibility of single-flame tube operation. The fed fuel heat is transferred evenly by means of flow components mounted on the water side, and it is then converted into steam without material stress.

The ZFR steam boiler series is also very well suited to the dynamic pooled output of several boilers. Important areas of use are those of commercial operations in all sectors of the economy, of processing industries and supply industries, as well as of
communal buildings.
