The latest technology

Stehender Röhrenwärmetauscher

Vertical heat exchanger 
(3-pass, 6 bar) with Efficiency Optimisation System (WOS). The automatic turbulators clean the flue gas path in the heat exchanger.


Flue gas recirculation
returns part of the flue gas flow to the combustion system. This optimises combustion and has a “cooling effect” which extends the operating life of parts in contact with the flame.

Stoker - Zellenradkombination

Combined stoker and rotary valve
Large stoker screw for safe fuel transport into the boiler. The patented Froling dual-chamber rotary valve ensures a safe separation between the burning chamber and discharge system.

Regelungssystem H 3200 Touch

Pre-wired H 3200 Touch control system
with internet connectivity


High-temperature combustion chamber
made of refractory fireclay components for maximum efficiencyand ultra-low flue gas emissions.

Vorschubrost mit langer Ausbrandzone

Moving grate with long combustion
for optimum adjustment to output and fuel quality.

Automatischer Ascherechen

Automatic ash rake
And ash screw for fully automated ash removal.
