Sioux Corp.'s mobile, self-contained cleaning and thawing systems are ideal for melting ice dams and thawing valves, culverts, hydrants, tanks, piping systems and drains. These mobile systems also can be used to thaw railroad cars to accelerate removal of viscous contents; remove oil and grease from equipment; prepare surfaces for painting; de-gas oil and gas tanks; sterilize and disinfect equipment and facilities; weed eradication; accelerate pre-cast concrete curing and thaw aggregate for concrete production. A Sioux trailer can be added to any Sioux steam cleaner, pressure washer or steam generator.
