Absolutely! We believe the real value of the Twister is unlocked when Twisters are permanently installed on a tank, allowing “Online Tank Cleaning”…allowing the tank to remain in service….and not just a conventional offline tank cleaning. The Twister is a unique technology that provides a proactive ability to manage the sludge problem, with the tank in service….not waiting until after the solids have become out of control, and requiring a reactive technology (vacuum trucks, dozers, robots, chemicals, manway cannons, etc). Provisions are built into Twisters intended for permanent installation to ensure no build up of solids around the swivel mechanism and to provide fail-safe protection against any leaks.
