SR Premium Screw compressors

Intelligent PLC control system

This system allows full customisation of the system air output and delivery by the user. The PLC is able to integrate with various IT solutions offering the user full remote control and system monitoring.

Cabinet

European design; maintenance focused configuration for quick servicing and less downtime This allows for reduced maintenance costs and less production loss, contributing to a very low total cost of ownership.

Visual warning system

VWS is designed to provide a visual indication of the machine’s operating status in noisy environments. This system uses industrial grade LED strip lights to show the current status of the machine through various colours. The system is programmed to display various colours for normal, fault, service and emergency operational status. *Not available in all markets.

Directly coupled motor structure

This allows for direct transfer of energy to the air-end master rotor or gear drive, increasing efficiency and reducing vibration.

Air-end

Long bearing life and class-leading efficiency are what the SR range focuses on. The SR series air-ends provide rock-solid performance coupled with a very long design life. SKF bearings are used and the RPM of the rotors are kept as low as possible. Rotors are balanced and size matched to enhance air delivery and reduce vibration and noise to an absolute minimum.

Electric motor

Electrical efficiency and performance stability are key points in the design of the SR range of screw compressors, as is motor protection. Standard IP54 motors are used. IE3 or IE4 motors can be supplied on request to provide you with the highest possible energy savings. All SR screws feature full PLC motor protection which covers low/high voltage, high current, high temperature, open phase, reverse phase and overload situations.

Variable speed drive

VSD equipped models are available to enhance energy efficiency and reduce total cost of ownership to the bare minimum. World-class brand name inverters are used and offer all the standard protection features one would expect in a premium machine.
