Customer benefits
Easy installation
The boiler is ready to be plugged in. Supplied with ready-mounted burner, control panel,
fittings and cables.
Compact design
The small footprint makes the boiler easy to incorporate.
Easy inspection and maintenance
To the greatest possible extent, all connections and valves are located on top of the boiler
- easily accessible during installation, inspection and maintenance. A number of manholes
facilitate internal inspection.
Easy to clean
The smoke tubes are fast and easy to clean thanks to the low number and efficiency of
the spiral tubes.
Uniform, high steam quality
The boiler’s efficient steam drier delivers a dry, saturated steam. A superheater can also
be installed.
Improved combustion
The furnace has a comparatively low heat release ratio and provides ample space for the
flame. This improves combustion and limits flue gas emissions.
Accessories
The boiler plant can be equipped with economizer, superheater, condensate tank, deaerator,
feed water tank, blow down tank, and O2 combustion control.
