Description Replace Lamson 300 HP Centrifigul Blower with a High Speed Turbo Blower.
Status Active
Justification The existing Lamson Blowers were placed in service in 2002 as part of the first iteration of the activated sludge process units. The blower is a "starts across the line", meaning that it is either on or off and cannot be regulated with Variable frequency drives. Because of this and its HP capacity, it has high starting amps that affect our electrical peak loading billing with REC. The New High Speed turbo blower uses a VFD which eliminates the inrush of power, allowing us to regulate our peak loading.

Budget Impact/Other By replacing the Lamson blower with a high speed turbo blower, we anticipate a 10% reduction in power cost for the foreseeable future. The estimated annual savings is less than $10,000 per year.
