Kaeser's Sigma Air Manager SAM balances service hours, prevents simultaneous motor starts, and maintains tight pressure control. SAM can be adapted to almost any system and manage up to 16 compressors or vacuum pumps - including multiple types and differing brands. It also manages dryers, filters and drains. SAM is the first master controller to incorporate an industrial PC with Internet technology. It alerts operators to service requirements and provides trending data for plant operational analysis. The standard Sigma Air Control basic software displays real-time operational status through an Internet browser on a PC, including system pressure trends as well as service and alarm messages.
