 N/A Sigma Control 2™: for all rotary screw compressors, rotary screw blowers, reciprocating compressors, boosters, and rotary lobe blowers
Sigma Control 2™ is based on advanced industrial computing technology. Interchangeable input and output modules enable flexibility for working with Kaeser rotary screw compressors, rotary screw blowers, reciprocating compressors, boosters, and rotary lobe blowers, as well as to external communications systems.

The next dimension of compressed air control
Kaeser Compressors has revolutionized compressed air controls with the Sigma Control 2™. With integration across Kaeser's extensive product range of rotary screw compressors, vacuum, screw blower, boosters, and integrated blower packages, this versatile control system enhances communi-cations and energy efficiency without sacrificing ease of operation.

Integrated Intelligence
Sigma Control 2™ is our most advanced integrated controller, combining safe and efficient internal supervision with important information and maintenance friendly features. The operator interface offers easy access to all settings and information. This controller provides a broad range of capabilities while at the same time is simple and reliable.

Protection For Your Equipment
Our control provides full time protection for the equipment. It monitors over 20 critical parameters including airend discharge temperature, direction of rotation, motor temperature, internal pressure, electrical overload status, filter differential pressure, and auto drain status (if equipped). The controller safely shuts down the machine to avoid component damage. Sigma Control 2™ also tracks service and load hours, which helps schedule routine maintenance and minimize downtime. It stores the alarm and operating history, aiding in faster trouble-shooting and reducing unscheduled downtime. The RFID feature provides secure access to the control menus, preventing unauthorized access and tampering.

Superior Energy Efficiency
Two-unit lead/lag sequencer programming is standard in Sigma Control 2™. This functionality equalizes runtimes, extends maintenance intervals and prevents unnecessary compressor starts. Further, it is pre-programmed with multiple user selectable control profiles (Quadro, Vario, Dual, Continuous, and Dynamic) to meet a wide variety of operating preferences. The precision electronic pressure sensor enables tighter switching differentials for further savings.

Flexible Communications
More and more customers desire the ability to remotely monitor or control their compressed air systems. Whether you have a standalone system or want to make it part of your plant-wide controls, Sigma Control 2™ was designed for maximum communication flexibility. Our built-in web server and Ethernet port (standard) let you view your equipment from any PC with a standard web browser. The open architecture makes it easy to integrate it into existing plant-wide monitoring systems utilizing optional communication adapters such as Modbus, Profibus, DeviceNet, and Profinet.
