Dual Fuel Burners

RLGB-MC Series Raadman Burner

Mechanical Modular Burners cover a firing range of 1000 up to 6,200 kW generally. They can be used wherever heat is needed in heating residences or hospitals, schools or offices, in industry or trade, on board ships and for mobile plant. They are suitable for all commonly available gas and oil types and are notable for their superior reliability, longevity, great economy and ease of manganese.
