Low NOx Industrial Oil,Gas & Dual Fuel
AirThe industrial burners ER series are designed particularly
for water tube boilers used in big civil installations and industrial
processes with a remarkable thermal demand. These series allows to
realize a modular and flexible combustion system adding a preparation
fuel unit (regulation pressure group set, preheating/pumping oil
station), a gas train, a control panel and a fan. It can also be used a
preheated air as in the oil dia-thermic generators and other heat
recovery systems. The modulating regulation always allows to reach a
wide modulation ratio and optimal fluid dynamics conditions for a good
combustion.
