The VARITOP® Tanktop System may be equipped on choice with spray balls or rotating jet cleaners always in connection with the same basic components.The connections ( interfaces ) are identical. In contrast to spray balls, where the cleaning effect is achieved by wetting the tank wall, rotating jet cleaners have the advantage of an additional mechanical cleaning effect by the slowly rotating fan-shaped jet and the associated interval rinsing. Optimal cleaning provides highest plant availability and product quality. Tuchenhagen rotating jet cleaners are availabe with function monitoring as an option. Each cleaner, whether a cleaning lance or a jet cleaner, can be adapted to the customers requests. A fixed cleaning lance or a rotating jet cleaner can maintain an optimal introduction length and an optimised spray ball.
