Tank cleaning nozzles can be used for both small and large tanks and are available as both rotating and static sprays.
Rotating nozzles are driven by the cleaning liquid by means of specially positioned nozzles. Rotational cleaners achieve very good cleaning of the entire tank surface as rapid-repetition impact loosens the dirt and washes it off the inside tank surfaces.
Static spray balls do not rotate. They are used primarily for washing down relatively small tanks and vessels. All tank cleaning nozzles are operating at low pressures.
