Project result · Colour-change optimisation

One flushing sequence. Half the solvent use.

In an existing project, revising the colour-change and flushing sequence reduced solvent use and associated VOC by 50%. The work changed three separate flushing operations into one optimised operation.

Separate flushing operations

Three 16-second operations became one 23-second operation.

The challenge: repeated flushing.

The project addressed repeated flushing, unnecessary solvent consumption and the work involved in colour changes. The goal was to simplify the sequence while supporting the painting process.

What changed in the recorded sequence.

Before

Three separate flushing operations, each lasting 16 seconds.

After

One revised flushing operation lasting 23 seconds, with fewer operator steps.

Nova Paint-Tech revised the control sequence. The published project result records a 50% reduction in solvent use and associated VOC.

How to read this result.

The public project record reports the sequence change, solvent reduction and associated VOC reduction. It does not publish solvent volumes, a measurement period or the customer identity. Those details are not inferred here.

Results apply to this individual project. A different paint circuit, coating material or operating requirement needs its own review.

Review the process before choosing the change.

Useful starting information includes the coating material, current colour-change steps, controller and valve arrangement, change frequency and available consumption records. An application review helps define which equipment, settings or sequence changes should be considered.
