The rotary spray heads are made of AISI316 stainless steel (apart from parts of the pneumatic actuator) and are mounted onto two bearings. All internal surfaces are carved with high precision machine tools, which provide a smooth polishing and high quality surfaces. The heads are available in two different lengths, for tanks with or without insulation.

The rotary head exits the cylinder (250 mm) pushed by a pneumatic actuator. The distance can be changed to fit the specific washing needs, thanks to two magnetic sensors placed on the actuator. It’s possible to reduce the stroke (how much the head will exit) by moving the magnetic sensor “A”. In order to have a stroke of less than 250 mm it is necessary to use a pneumatic distributor with “closed centers”, in order to avoid that the washing fluid pressure
is superior to the actuator’s thrust.
The magnetic sensors permit to integrate the rotary head with a C.I.P. plant logics, by signaling the position of the washing head. This is very important if the tank contains agitators that can damage the rotary head when moving. Its speed varies depending on the washing fluid pressure that needs to be limited. An excessive speed in the rotation breaks the flow into drops, reducing the impact strength (see table 10).
During the washing phase, a watertight system keeps the washing fluid away from the pneumatic actuator. When the C.I.P. process is finished, the pneumatic actuator is activated and the rotary head returns to its initial position inside the cylinder.

Max washing range:
In order to define the actual washing distance of a rotary head, we need to identify the processing conditions, like the kind of product to eliminate, the washing solution, the pressure and temperature of the washing jets. Each value needs to be determined through specific trials. What we can define, is a “wetting range”, which is the max distance a head can reach, wetting the whole internal surface of a tank.
