This type of spray ball offers a fairly low cost, low maintenance option.
However relatively low pressures are required resulting in longer cleaning times
Cleaning times of 30 – 40 minutes are not unusual.
Atomisation can be a problem when pressures exceed 3 Bar. The maximum effective rinse range of this type of ball is between 2 & 3 metres.
The spray pattern for each ball is fixed, however there are a wide range of spray patterns available to suite a wide variety of vessel shapes.
The slotted rotating spray ball has evolved from the standard ball, offering the ability to handle somewhat higher pressures, with the inevitable reduction in cleaning times.
Maintenance costs are higher than for a standard spray ball but lower than for a rotating jet.
Careful selection of the correct design of spray device is of vital importance to the effectiveness of any C.I.P system
