Sioux Corp.’s Steam-Flo waste-oil burner helps lower fuel costs while providing hot water or steam for a fleet’s operation. The unit, which burns 2.9 gallons per hour of waste oil and produces 345 pounds of saturated steam per hour, is suited for commercial greenhouses, nurseries, precast concrete, ready-mix concrete plants and industrial applications such as closed-loop heating systems, heating steam jackets and thawing pipes and valves.
