SafeSteam™ Steam Cleaners

Sioux Corporation now manufactures the Walters SafeSteam™ fireless steam cleaner line. The SafeSteam™ lets you use your plant's internal steam as a powerful steam cleaning tool!

If your plant has 80-150 PSI (5.5 -10.3 BAR) steam, here is an innovative way to use that steam for cleaning purposes. The SafeSteam™ is a steam cleaner that has many benefits over conventional steam cleaners. It utilizes your existing steam system, which eliminates the requirements for a burner, and it uses less water, fuel and electricity than a pressure washer.

No Burner, Exhaust or Fuel Tanks to Fill
Plant steam by itself is too dry for effective use in cleaning applications. SafeSteam™ combines your plant steam with cold water to create a powerful steam cleaner that can be used for plant maintenance and sterilization. By using your existing steam, there is no need for a burner, which eliminates combustible fuel and tedious burner maintenance. Without a burner, there is no exhaust, so the machine can be used indoors without air contamination or special venting.

SafeSteam Saves You Money and Time
SafeSteam is always instantly ready. Operators just pick up the gun and go to work. SafeSteam is easy for your internal maintenance team to maintain. No dealer or costly service contracts are required. Because of its simple, streamlined design, it’s at least $1,000 less expensive than conventional steam cleaners.

Convenience & Power for Tough Cleaning Jobs
SafeSteam™ can be used for sterilizing, cutting through heavy grease, paint preparation, cleaning delicate equipment and sensitive parts, and many other tough cleaning jobs. It can be used just about anywhere inside or outside your facility where you need the power of a steam cleaner without the splash-back of a pressure washer.
