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 time spent cleaning by 80 percent. Compact in design and easily maneuverable at 11 inches tall and weighing 14 pounds, it saves space while maintaining the impact, durability and range required for optimal impingement tank cleaning. It is available with directional nozzles that concentrate the cleaning power downward, enabling grease and other debris at bottom corners of tanks to be blasted away quickly and efficiently. Operating between 50 and 300 psi and 50 to 120 gpm, it has a cleaning range between 35 and 50 feet and can completely clean a tank in eight to 12 minutes. 610/408-9940; www.gamajet.com.
