Rotary Spray Head Technologies

Application. The rotary spray head is an efficient replacement for the traditional static spray balls as it uses low volume of liquid at low pressure. The units are particularly well suited to sanitary applications in tank sizes ranging from 0.1 to 50m 3 and up to 350 3 m with the use of the Sani Mega.

Working Principle The flow of the cleaning media causes the head of the rotary spray ball to rotate by the reaction of liquid leaving slots cut into the ball at a tangent, with fan type jets laying out a swirling pattern across the vessels internal surfaces. These fans generate a vibrating impact which creates a cascading coverage pattern down the height of the vessel. The units are totally self cleaning with this being achieved by directing the cleaning media through the rotating bearing track and onto the neck and around the elongated head.
