CIP CIRCUIT ENGINEERING

Two-Tank vs Three-Tank CIP

Tank count describes storage duties. It does not identify independent circulation capacity or a cleaning recipe.

Two-Tank vs Three-Tank CIP: Media Allocation & Return
Review item	Two-tank arrangement	Three-tank arrangement
Media allocation	Name two separate duties and how any additional medium is prepared.	Name the third duty; do not assume it is another cleaning circuit.
Changeover	Check preparation and drainage between incompatible phases.	Check segregation, extra valves and each vessel’s own cleaning.
Concurrency	Trace the installed supply and return paths.	A third tank alone does not add another pump or heater.

Draw each phase

For rinse, cleaning medium and final rinse, mark the source, selected equipment and return destination. A tank label without this path can hide mixing or an unassigned reject stream.

Compare usable inventory

Ask for minimum suction inventory, circuit hold-up, delayed return and reserve for the same operating case. Compare the defined working inventory instead of external tank dimensions.
