Cleanpac 700 Cleaner

The Cleanpac 700 is a high-efficiency, 6 inch diameter cleaner, featuring an innovative system design based on satellite assemblies. The innovative satellite design concept permits installation in virtually any available space, for any range of current and future capacity. Isolation valves can be easily installed in the system at any time.

Key Benefits

1. High Cleaning Efficiency
2. Lower Reject Rates
3. Better Runnability
4. Single-Satellite Isolation
5. Easy Maintenance

High Cleaning Efficiency
The Cleanpac 700 cleaner is designed for highly efficient removal of sand, bark and shives. Despite its large diameter, the Cleanpac 700 can outperform the cleaning efficiency of many cleaners with smaller diameters, in certain applications. This has been achieved with a totally new inlet head design, a long cone and a new reject outlet.

The feed flows into the upper cone through two inlets in the cleaner head. This design feature, combined with an accelerated flow created in the head and a longer retention time, contributes to the development of a high separation effect. Mounting of the satellite directly to the feed pipe also facilitates a smooth and balanced flow. This design ensures a minimum loss of energy in the piping. As a result, input energy is applied effectively for the separation of fiber and contaminants. The established flow and pressure drop are constantly maintained. The design also ensures that no air pockets are created in the feed pipe.

Lower Reject Rates
Due to the high separation efficiency and reject outlet design, the Cleanpac 700 cleaner can be operated at a significantly lower reject rate than comparable large diameter cleaners.

As a result of the low volumetric reject rate, subsequent cleaner stages can be equipped with fewer cleaners, or a stage can be eliminated, with no loss in plant efficiency. This advantage can significantly reduce investment costs in a new cleaning plant.

Better Runnability
The 6 inch Cleanpac 700 cleaner offers the same cleaning efficiency as smaller cleaners, with the added advantage of better runnability and exceptionally low plugging. Smooth runnability is also ensured by the specially designed rejects chamber which permits use of a large outlet. The large reject outlet also minimizes the risk of plugging, caused by oversized particles.

Single Satellite Isolation
The satellites connect to a main header assembly that can be equipped with a cutoff valve to isolate the satellites from the cleaner plant. This offers the flexibility to adapt capacity to changes in production, as well as permitting cleaner replacement and service during operations. Standby satellites can be easily installed.
