Spraying Systems Co.”s Retractable Tank Washer (RTW) is designed to automate the cleaning of tanks up to 40 feet (12 m). The system eliminates time-consuming, dangerousmanual cleaning, reduces consumption of costly chemicals and water, andcleans tanks thoroughly and consistently. The RTW also eliminates theneed for workers to manually insert and remove the tank washer from thetank/reactor. A pneumatic mechanism lowers and raises the tank washerat the beginning and end of cleaning cycles.
