Baghouse Controllers – Key to Increasing Dust Collection Efficiency
Often times the key to baghouse efficiency is operating the pulse jet cleaning system correctly. Both over-cleaning and under-cleaning your bags will cause problems. A simple upgrade to a new clean-on-demand dust collector controller from an older, less-efficient baghouse timer board usually results in more cost savings than larger investments such as new bags or system modification.
With a clean-on-demand (pulse-on-demand) control system, your dust collector cleaning system will only activate when its needed, no more, no less. Simply set the upper and lower (low/high) differential pressure points, (normally 3.5” and 5.5” w.g.), and the controller will trigger the cleaning cycle only when the DP rises above the high setting, and will continue to clean until it drops below the low setting. This results in the bags being cleaned less frequently, saving on costly compressed air and reducing wear on the filters themselves. Additionally, it lowers overall emissions and helps regulate the system performance by keeping it running in a consistent differential pressure range.
For these reasons and more, our advanced system audits frequently recommend switching to new baghouse pulse controller as an easy way to improve efficiency, reduce operating costs, and increase system capacity/performance.
