Modulating Gas Burners
The GAS P/M series covers a firing
range from 80 to 4885 kW. Operation is featured by progressive two
stage operation or full modulation, with an advanced modulating control
system and probes. The burners of GAS P/M series are well suited for
applications requiring versatility of control process, steam,
refrigerating absorption where a variable output is needed.
Due to
their metal sheet structures, they are specifically suitable for
process applications where plastic materials could be easily damaged or
deformed. Simplified maintenance is achieved by sliding bars which permit the
access to the combustion head without need of removing the burner from
the boiler.
