Butterworth Tank Cleaning System

A mechanical device used for the purpose of cleaning oil tanks by means of high pressure jets of hot water. The apparatus basically consists of double opposed nozzles which rotate slowly about their horizontal and vertical axis and project two streams of water through all possible angles against all inside surfaces of the space being cleaned. The tank washing machines can deliver sprays of water at various temperatures and pressures that are dictated by the type of cargoes carried and the reasons for cleaning (Quick bottom wash through gas-freeing and tank entry for hot work).
