Unlike conventional fluid-driven rotating nozzles where cleaning efficiency decreases as pressures increase, our Rokon® tank washing nozzles increase cleaning impact as the fluid pressure increases. The nozzles rotate at a constant speed of approximately 10 RPM when fluid pressure is between 15 to 230 psi (1 to 16 bar). Higher fluid pressure results in a direct increase in impact of the cleaning fluid. And high-impact spraying means liquid consumption is minimized and cleaning efficiency is improved. The limited rotational speed of the nozzle makes it highly useful for cleaning, sanitizing and foaming applications. Choose from a wide variety of sizes, capacities, materials and spray coverages.
