Air Compressors

Save Energy – Save Money

Bullworthy and HPC Compressed Air Systems have earned a reputation for excellence in all fields of compressed air generation whilst providing expert, professional advice. Put simply and straightforward, Bullworthy and HPC can help you save energy, save money and to benefit the environment by reducing your businesses CO2 emissions.

Every HPC rotary screw air end is equipped with energy saving SIGMA PROFILE rotors manufactured to the highest standards with precision aligned roller-bearings ensuring long service life with maximum reliability.

The Next Dimension

The SIGMA CONTROL 2 features a highly flexible modular design, yet its standard construction means that this versatile control system can be matched to suit the needs of any rotary screw compressor or rotary blower from HPC’s extensive range.

Comprising a main control unit and separate input/output modules, this modular concept therefore enhances communication and maintenance-friendliness.


The Control Centre

The control unit features an easy to read display and durable input keys; all relevant information can be viewed at a glance. User-friendliness is further enhanced by the logical menu structure and the ability to display data in any one of 30 selectable languages.

Stay Connected

The Ethernet interface (10/100 MBbit/sec) allows users to directly call-up operational parameters on a connected PC network via the integrated web server. Optional modules support Modbus-RTU, Modbus/ TCP, Profi bus DP-VO, Device-Net and Profi-Net IO.

Your Security

The addition of RFID functionality to the SIGMA CONTROL 2 means that service work and system changes to the compressor can be performed only by authorised personnel, e.g. suitably qualified KAESER service partners.

Update & Save

Software updates and operational parameters can be quickly uploaded and transferred via the convenient SD card slot. This both minimises service costs and allows the SD card to be used for (long-term) storage of key operational data.
