“No dusts are equal, but some dusts are more equal than others.”
(Dr. Thomas Schwalbe)
It matters, how quickly a dust clogs a filter. Conventionally a preset change in differential pressure triggers filter cleaning by a pressurized air pulse. The set point for the differential pressure triggering the cleaning is aimed to prevent a migration of dust into the deeper layers of the filter media and to keep the pleat stability at its best performance. When the filter is cleaned too late, it does not revert to its original performance, it then operates at a higher pressure loss.
And then the optimal operating point for a filter media is yet a different issue. One worthwhile assumption is that a filter media should be cleaned when the increase of its pressure loss reaches the cleaning set point. But what is the optimal set point for cleaning? Tricky question!
Fortunately, you do not need to worry about optimizing filter cleaning cycles. At TRM Filter we have developed a proprietary Rotatronic-smart filter cleaning technology that is based on 6 sigma process optimization.
With the aid of the computerized algorithms of our Rotatronic smart-filter cleaning technology our dedusting filter systems learn about the clogging tendency of their filter cartridges, the evolution of differential pressure in the course of the dedusting filter’s operation with the media filtered.
With a starting set of cleaning trigger points, the Rotatronic smart filter cleaning technology monitors the evolution of differential pressure, evaluates it and sets itself new operating conditions and cleaning trigger points.
With the aid of Rotatronic smart-filter cleaning technology an irreversible filter media dust load is prevented. The media are being air purged at a progressively ideal point of their operating cycle. Their behavior, including their aging, becomes predictable. They are being run at best efficiency.
