Available Technologies

Advantages

New certification

CE certification as a whole according to the PED Directive

High steam quality

At high load the internal separator prevents the entrainment of water droplets to the steam outlet, the steam produced is then always of high quality having a very high dryness fraction.

Reduced size

Redesigned to optimise the dimensions for the installation in small-size heating plant rooms and to facilitate routine maintenance and inspection operations

Simplified user interface

Latest generation user interface provided with warning and alarm systems

Reliability and durability

Maximum reliability and durability guaranteed through design with low surface heat losses.

Consistant supply of high quality steam

Thanks to the generously dimensioned steam chamber the boiler can meet the varying demand of the system including instantaneous peak demands
