LITTLE GIANT “LG-SERIES”
The Electro-Steam Generator design consists essentially of a high pressure chamber filled with water
that is heated by one or more submerged resistance type electric heating elements. Automatic controls
are provided to maintain the pre-set operating pressure and water level. Safety features include:
automatic low-water cutoff (manual low-water reset optional), dual pressure controls, safety valve, and
visible water level gauge. All of our generators are built in accordance with A.S.M.E. Miniature Boiler
Code and are individually inspected and stamped by an Authorized National Board Insurance Inspector.
