The new standard G type NOVANTA series Low NO x burners Class 2 (< 120 mg/kWh), made in aluminum housing with a backward curved centrifugal impeller is studied and developed to get high performance and efficiency combined with low emissions. This series with a maximum power of 3.100 kW, are in this selection of product that is particularly competitive. The userfriendly application and maintenance are the strengths of these burners.

Back-pressure in combustion chamber (mbar) Back-pressure in combustion chamber (mbar) G310A PR-MD...SR 140 Minimum inlet gas pressure (mbar) Minimum inlet gas pressure (mbar) Attention: the graph shows the value of the gas output (kW) against the corresponding pressure without the combustion chamber back pressure. To know the minimum gas pressure at gas train, in order to get the gas output, it is necessary to add the boiler back pressure to the value read on the curve.
