Chemical and Pharmaceutical Applications


All-Electric Pressure Washers Clean Chemical Plants without Contaminating the Air

For over 30 years, Sioux Corporation has been the industry leader in manufacturing heavy-duty, extremely dependable all-electric hot water pressure washers and steam cleaners. Rather than using a conventional oil or gas fired burner, these machines heat the water using electricity. Sioux’s line of 100% All-Electric hot water pressure washers and steam cleaners are being used in chemical and pharmaceutical plants world-wide.



  • These units have fewer moving parts and contain a conservatively designed heating element, providing the highest reliability and trouble-free operation of any design. 
  • These cleaners are excellent for general plant maintenance and sterilization.  
  • E-Series.jpgSince there is no burner, All-Electric units emit no contaminants into the surrounding air and comply with the Clean Air Act
  • Explosion-Proof models for use in hazardous (combustible) atmospheres are available.  
  • Units are designed for indoor or outdoor use.  
  • They require no preheating or recovery time, making hot water available immediately.  
  • For optimal cleaning efficiency, the discharge temperature is maintained continuously.  
  • Sioux offers over 45 models of All-Electric steam cleaners, hot water pressure washers and combination units, all with many standard options available.  
  • Standard ratings for steam cleaners range from 0.6 - 3.8 GPM (2.27 - 14.38 LPM) at 100 PSI (6.9 BAR). For hot water pressure washers, the ratings range from 2.3 - 5.7 GPM )8.7 - 21.6 LPM), 600 - 3000 PSI (41.4 - 206.85 BAR).
