Specially designed to de-sludge crude oil storage tanks by re-suspension of the crude oil sludge. The P43® Sludge Control Machine directs a powerful jet(s) of oil that sweeps and rotates through the sludge at the base of the tank and blends the soluble hydrocarbons into the total contents. Formerly available through Progressive Technical Services, the P43® is now distributed world wide by Veolia Environmental Service's industrial services team.
