SCREW COMPRESSORS

A full range of variable speed drive systems developed by adopting advanced European inverter technology. The Variable Speed Drive Series features stable running user-centered systems, optimised full-function protection and a 3D touchscreen with an intuitive user interface. We offer a full range of variable single- and two-stage machines in both the SR and DB ranges. Savings of up to 30% are common with the Variable Speed Drive (VSD) models.

Trough the intelligent control system Vector Conversion Technology ensures the motor delivers the proper torque control whilst maintaining minimum motor temperatures. The control system calculates the exact corresponding current component references required. The control system also allows for full torque to be delivered at any RPM and the sudden acceleration and declaration of the system to meet sudden changes in air delivery demand. It also minimises temperature, noise and vibration and extends the service life while concerving energy. 

SR SERIES PREMIUM

SR Series Premium Screw Compressors  is a performance focused solution that delivers value and world-class efficiency and energy saving. The advanced control system offers total IT integration.

SR Series Premium Screw Compressors are available from 100HP upwards. The Premium Models are a perfect solution for clients with very demanding air-production requirements that need high efficiency and extremely reliable machinery.

FEATURES

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.

SR SERIES ECO LINE

SR Series Eco Line Screw Compressors were designed as a “nothing unnecessary” screw air compressor. The Eco Line Models are a perfect solution for clients that are solution focused and require reliable compressed air production. 

SR Series Eco Line Screw Compressors are available from 100HP to 350HP. 10HP to 60HP utilise a standard PLC system that offers easy operation an comprehensive protection. Engineered simplicity and reliability are what you get from the SR Eco Series. 

FEATURES

LOWER PRODUCTION COST
The design, and thus manufacturing process have been greatly simplified, meaning lower production costs.

ADVANCED PLC
Models from 75hp up utilise a more advanced touch-screen PLC system depending on the model being fixed or variable speed, single or 2 stage.

HIGH PERFORMANCE AIR-END
Models from 75HP up use the same air end structure as the SR Premium models, however, motor efficiency is only offered at an IE1 level.  

PMM MOTOR STRUCTURE
Variable Speed models come standard with Permanent Magnetic IP54 motor structure across the range.

CUSTOMER FOCUSSED CABINET STRUCTURE
SR Economy Series screw compressors still have the benefits of a customer focussed cabinet structure allowing for quick and easy servicing.

SERVICE SPARES
All parts and spares are well priced and offer cost savings benefits to solutions focussed clients.

BUILT TO LAST
Although designed as a cost effective compressed air solution, durability is not compromised, SR Eco series models can work in the same harsh environments as the SR Premium models and provide years of stable service.  Model ranges include fixed and variable speed, single and two-stage variable speed and tank mounted package units up to 30hp.

DB SERIES PREMIUM

The DB Series Premium Screw Compressor is a performance focused solution that delivers value, world-class efficiency and energy savings combined with an advanced control system that offers total IT integration. 

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.

The system is programmed to display various colours for normal, fault, service and emergency operational status  (Not available in all markets.) .

DIRECTLY DRIVEN MOTOR STRUCTURE
This allows for direct transfer of energy to the air-end master rotor, increasing efficiency and reducing vibration. This system is used from 10hp up to 50hp in an 8 or 10 bar pressure output. Larger machines use a directly-coupled transfer system. Belt drive configuration is available on request.

ELECTRIC MOTOR
Electrical efficiency and performance stability are key points in the design of the DB range of screw compressors, as is motor protection. All DB screws feature full PLC motor protection which covers low/high voltage, high current, high temperature, open phase, reverse phase and overload situations.

DT SERIES

The DT Series Screw Compressors offer a compact and modern European design. The small space requirements means quicker and easier machine placement which allows for less downtime during installation.

Direct-Drive Models offers ultimate energy savings and are available from 10HP up to 350HP in standard, VSD and 2-Stage Models. Acoustically dampened cabinet design utilises intelligent design to keep noise inside the cabinet and provide silent and vibration-free operation.

FEATURES

CABINET
European design Compact European design is both modern and aesthetically pleasing in appearance. Small space requirements mean machine placement is far quicker and easier then before allowing for less down-time during machine installation. owder-coated panels are durable and corrosion resistant. A new magnetic panel locking system on the DT models make panel removal and placement quick and easy further enhancing inspection and service functions.

SILENT OPERATION
Acoustically dampened cabinet design utilises intelligent design to keep noise inside the cabinet and provide silent and vibration-free operation.

AFTER COOLER
Top mounted after cooler for efficient cooling and easy cleaning. The top panel is removable allowing easy access to the cooler from the bottom and top, cabinet disassembly is quick.

PRACTICAL DESIGN
Intelligent design focuses on efficient placement of internal components, allowing for easy and quick replacement of service parts and spares.

DIRECT DRIVE SYSTEM
The direct drive system is loss-less and power transfer is near 100% from motor to air end. The motor-air-end assembly is both simple and cost effective to produce and replace. Air-end repair costs are no longer a concern as air-end replacement is far more economical with this brilliantly efficient design.
