The Twister Manway is presented in this free brochure as manually adjustable and engineered for any manway to API 650.
Designed for online or offline tank cleaning and maintenance, The Twister permanently installs on crude oil, heavy fuel oil, or catalyst fines tanks. It provides for minimized downtime in offline cleaning and/or tank entry. The manway also provides a method for online tank cleaning so a tank only needs to be opened for mandated inspection intervals.
The Twister works by taking suction from the tank with a proerly-sized recirculation pump. It pumps product back into the tank through its manually adjustable nozzle. The nozzles creates a powerful jet of tank contents that is directed across the bottom of the tank. This dissolves and resuspends accumulated sludge. Its 120° sweep allows a tank to be thoroughly mixed. Multiple Twisters are usually installed on a given tank depending on size, product contents and requirements.
