Master Controllers

Supplied as belt drive from 2.2 kW - 22 kW & direct drive from 18.5 kW - 450 kW. All compressors have an operating pressure range from 5.5 bar - 15 bar, rated at 100% Full Load Duty. Lower pressures are available on request. Please contact us if you have a specific requirement or require further information / advice.

Industry 4.0 – Intelligent maintenance and efficiency management

The SAM 2, the next generation master compressed air management system, uses the adaptive 3-D advanced control to make compressed air production and treatment not only faster, but also more efficient and reliable.

3-D advanced control analyses all operating data on an ongoing basis, simulates alternative actions and calculates the perfect compressor combination. The result: Unprecedented energy efficiency.

Maintain an overview at all times thanks to easy operation, visualisation and analysis. With secure network technology – conveniently from any PC.

Predictive maintenance by Kaeser specialists prevents unplanned downtime.

And if you have big plans for the future: The SAM 2 is ready-designed to accommodate potential compressed air station expansion. A simple software upgrade allows an expansion of the master controller without the need for additional investment in new hardware.

Your advantages

The SAM 2 not only records switching losses, but also gathers information regarding all dimensions that affect your compressed air station. Using this data, the SAM 2 then calculates the perfect parameters for optimum performance and controls all connected components accordingly.

Together with the powerful Ethernet-based KAESER SIGMA NETWORK, the SAM 2 forms a future-proof infrastructure that meets all requirements for a highly secure industrial control system.

Continuous fine adjustment with a view to achieving optimum energy efficiency (energy management in accordance with ISO 50001) and the option of predictive, demand-oriented maintenance keep life cycle costs to an absolute minimum.

Adaptive 3-D advanced control

The innovative adaptive 3-D advanced control not only takes switching losses (start / stops) into account, but also considers additional parameters that influence compressed air system energy efficiency, such as energy consumption due to control losses (idling FC losses) and pressure flexibility.

The adaptive 3-D advanced control ensures optimum efficiency at all times by continuously analysing the relationship between these parameters, predictively calculating the optimum values from various possibilities and by controlling the connected compressors accordingly. The demand pressure provides the foundation for adaptive calculation of switching events and is therefore kept to an absolute minimum.

Simple software upgrade for compressed air station expansion

SIGMA Control Basic

The SIGMA CONTROL BASIC is available with KAESER's SXC, SX, SM, SK and ASK series rotary screw compressors. It is the perfect solution for users who initially require a single compressor for their air supply, but who also may wish to expand the compressed air system in the future. Furthermore, KAESER’s modular control and compressed air management concept ensures trouble-free system compatibility.

SIGMA Control Basic – Functions

Quick and simple operation with clear icons and large display

Fully automatic DUAL control (full load/ idle/ on/off control)

Monitoring of air network pressure parameters, airend temperature and direction of rotor rotation

Counter for service, load and operation hours

Adjustable service intervals, pressure and temperature unit selection (bar/ psi/ MPa, °C/°F)

Nominal system pressure can be adjusted separately

Adjustable switching differential

Group alarm volts-free contact

Electronic pressure transducer

SIGMA CONTROL 2 – Fitted to all ASD – HSD Compressors as standard. Optional on SX – ASK Compressors.

Sigma Control 2 (SC2) – The latest evolution in the Kaeser on-board machine controller provides several new innovations in Energy Efficiency.

New Control Modes like Dynamic Control measures the operating temperature of the main drive motor continuously enabling the SC2 to determine the best course of action for the compressor, whether it is more efficient to stop or continue running.

Update and Save

Built in SD Card slot. This enables the controller to be easily updated. Additionally the SD Card is used for full operational data storage for future download to identify machines service history, utilization etc.

Your Security

RFID functionality ensures that the system remains secure, so that only authorized personnel can make changes to the units system.

Stay Connected

The Ethernet interface (10/100 MBbit/sec) allows users to directly call-up operational parameters via a connected PC network. Optional communications modules support Modbus-RTU, Modbus/ TCP, Profibus DP-VO, DeviceNet and ProfiNet IO. It also has the ability for 2 Off Kaeser / HPC Compressors to be connected together for Master/Slave Control in the event of future requirements.
