Giersch RG20-N Single-Stage Gas Burner
Giersch RG20-N Single-Stage Gas Burner
Giersch RG20-N is a fully automatic, single-stage forced-draught burner designed for operation with natural gas. Its 40–120 kW output range makes it suitable for heating boilers used in residential, commercial and industrial applications.
The burner operates with LL and E natural gas types. Precise adjustment of the gas and combustion-air supply ensures reliable ignition, stable combustion and efficient operation. Flame supervision is provided by an ionisation electrode, while the automatic operating sequence is managed by a Siemens LME11 control box.
RG20-N is a single-stage model without modulation. The RG20-M-L-N should be selected for modulating operation, while the RG20-Z-L-N provides two-stage sliding operation. Depending on the required capacity and gas-supply conditions, the burner can be equipped with a KE10, KE15 or KE20 compact gas train.
