Alfa Laval GJ 8 Working Principle

The Alfa Laval Gamajet 8 Rotary Jet Head uses fluid-driven rotation to create high-impact jets, systematically covering the tank interior with powerful mechanical cleaning action. Its nozzle configuration provides consistent, repeatable 360° coverage to efficiently remove contaminants and residues from tank surfaces. The device achieves effective cleaning using fewer resources—saving water, cleaning agents, energy, and ultimately, operating costs.
