The DT-550DC is a specially designed drum crusher that will completely drain liquid residue from used 30 to 55-gallon drums. This is possible due to the piercing plugs under the crusher press-plate, perforating the drum. The liquid that is extracted is drained directly into an integrated oil-reservoir in the bottom of the crusher. This means that used oil-drums can be delivered onshore as ordinary metal or scrap iron. The DT-550DC is a closed crusher system so operators will avoid any direct contact or exposure to chemicals.
