Master Controller Helps Optimize WWTP Aeration Systems

Kaeser Compressors’ Sigma Air Manager (SAM) 4.0 is a master control system for all production systems. It can control up to 16 blowers and only turns them on when they are needed to meet air demand. This improves system stability, reduces energy use and equalizes blower run time.

SAM 4.0’s advanced communications capabilities make connecting with plant supervisory control and data acquisition (SCADA) systems easier than ever before. Using the desired system flow rate calculated by SCADA, SAM 4.0 selects the most efficient combination of units to produce the required flow, keeping energy costs as low as possible.

This master controller also provides plant managers with status messages and alarms to help minimize downtime. Using the built-in Kaeser Connect capabilities, WWTP staff can remotely monitor operating status, maintenance schedules and energy usage on any network device. The SAM 4.0 is compatible with Kaeser’s rotary lobe and rotary screw blower packages, which are designed for wastewater service and offer wire-to-air efficiency.
