SIGMA Control BASIC (SCB) - Compressor Controller


SIGMA CONTROL BASIC (SCB): designed for small compressors without the need for communication, SIGMA Control BASIC has everything necessary for good compressor control and is fitted as standard to the SXC Series of oil-lubricated modular rotary screw compressor packages.

Previously, SIGMA Control BASIC (SCB) was the standard compressor controller for all HPC KAESER oil-injected belt driven rotary screw compressor models across the SX - SM - SK and ASK Series screw compressors prior to the launch and upgrade to SIGMA Control 2MCSIO (SC2IO).
