Tradebe's "SLUDGEBUSTER" cannon is a stainless steel robotic equipment, which can be folded and fitted through a 24” manway. It is capable of tracking forward and backward and passing solids up to 2” in diameter. Tradebe is the industry leader with this technology because we own the patent for the equipment and process. The process includes the Ruff unit, which is a trailer mounted with a removable skid consisting of hydraulic pressure pack, fluidization pumps and fuel oil storage tanks - everything required to complete your tank cleaning project.
