The Sioux Steam-Flo® is a perfect source of low pressure steam for a variety of commercial and industrial applications. This unit can be used in place of a conventional boiler for a variety of commercial and industrial applications. The generator produces 370-845 lbs. per hour of saturated steam in minutes. The Steam-Flo provides continuous, unlimited steam. The unit is easy to maintain and built to last. Mountings include portable, stationary, or over-the-road trailer. The unit can be outfitted with an optional water tank and generator for completely self-contained operation. Because of its portability, the Steam-Flo is excellent for use in overflow production and outlying area.
Steam-Flo generators are often used in commercial greenhouses, nurseries and industrial applications including heating steam jackets, and thawing pipes and valves.
