Atlas Copco redesigns screw-compressor range

Atlas Copco Compressors has redesigned its smallest oil-injected screw-compressor range - the GA 5-11/GA 5-15kW Variable Speed Drive (VSD).

This range offers a new-generation compression element, an eight per cent increase in air delivery, noise levels as low as 60dB(A), VSD voltage variants, an extended operating range, an Elektronikon controller and an additional tank-mounted GA 15 VSD model.

SER (Specific Energy Requirements) are lowered by up to eight per cent, achieved by the introduction of a screw-compressor element within an enhanced package.

FAD (Free Air Delivery) has also been increased by up to eight per cent.

For applications where the compressed air demand fluctuates, the advanced control algorithms of Atlas Copco's VSD (Variable Speed Drive) create average energy savings of up to 35 per cent.

The GA 5-15 VSD range has been equipped with saver cycles on fan and dryer.

Installation flexibility is a major characteristic of the GA 5-11/GA 5-15 VSD range.

Atlas Copco's WorkPlace Concept is reinforced with operating noise levels starting from as low as 60dB(A).

Installation cost is minimised by extending the standard operating range in ambient conditions up to 46C, eliminating the need for a dedicated compressor room.

More VSD models, including a tank-mounted GA 15 VSD and standard voltage 200/575 variants, reduce installation costs further.

Compressor reliability is increased by the improved belt-driven drive train.

The introduction of the Elektronikon MkV Graphic Controller in the GA 5-15 (VSD) allows for remote online monitoring through a simple Ethernet connection.

This internet-based compressor operation visualisation increases equipment reliability and efficiency by offering a variety of control and monitoring features.

The graphic controller (a standard feature for the VSD unit) is capable of simultaneously controlling up to six compressors.

Reliability is further improved by the introduction of an integrated dryer range.

Downstream equipment is protected from contamination, even in demanding environmental conditions.
