The EZ-8 automated rotary impingement tank-cleaning device from Gamajet, part of the Alfa Laval Group, eliminates the need for manual cleaning, while reducing water and chemical usage by 85 percent and cleaning time by 80 percent. It is compact and easily maneuverable at 11 inches tall and 14 pounds. This allows for space saving while maintaining the impact, durability and range required for optimal impingement tank cleaning. It is available with directional nozzles that concentrate power downward, enabling grease and other debris at bottom corners of tanks to be blasted away quickly and more efficiently. Operating between 50 and 300 psi and 50 to 120 gpm, it has a cleaning range between 35 and 50 inches, and cleans a tank in 8 to 12 minutes. 610/408-9940; www.gamajet.com.
