The Sanitaire Blower Group Controller (BGC) provides automatic control for multiple Sanitaire TurboMAX or TurboLIGHT blowers to help optimize operational efficiency of wastewater aeration grids.

In a typical wastewater treatment plant, the blowers in an aeration system are the single highest energy consumer. While Sanitaire’s high-speed turbo blowers already deliver 30 to 40% lower power consumption compared to other blower technologies, the integration of our plug-and-play Blower Group Controller can further improve efficiency.

Up to 15% energy savings

Designed by the aeration experts at Xylem, the Sanitaire BGC optimizes the efficiency of a group of blowers by selecting the most efficient operating configuration to achieve necessary air volume. This can reduce blower power consumption by up to 15%.

Expert control algorithm

The Sanitaire BGC uses an advanced control algorithm to manage duty, assist, and standby blowers based on defined air pressure or dissolved oxygen setpoints.

By equalizing blower speeds and rotating blower duty based on total hours run and number of starts, the Sanitaire BGC not only improves blower efficiency but also extends blower life and reliability.

Simple installation and integration

Commissioned on-site by Sanitaire engineers, the Sanitaire BGC provides simple installation and integration with plant SCADA systems.  

The BGC includes a door-mounted HMI touchscreen to monitor system status and tune transition setpoints to accommodate process changes over time. It also provides a single point of access for SCADA connectivity to all blower data, including discharge pressure and temperature, flow rate and temperature, filter pressure drop, and more.
