Alfa Laval GJ 4 Rotary Impingement Tank Cleaning System

Alfa Laval GJ 4 is a hydraulically driven rotary tank claning machine that revolves 360° in both horizontal and vertical planes, to provide a tight, thorough scouring pattern that covers all interior tank surfaces in one complete cycle.

A choice of twelve nozzle sizes and hydraulic turbines and stators offer a wide range of flow rates, nozzle rotation speeds, and wash cycles.
