ADVANCED SCROLL TECHNOLOGY
Air compression is achieved by the interaction of a fixed and orbiting scroll. Air at inlet pressure enters the
compression chamber at the exterior side of the scroll element. Once air is drawn in, the orbiting scroll seals
off the inlet port. As the scroll continues to orbit, the air is progressively compressed into an increasingly
smaller ‘pocket’. A continuous flow of compressed air leaves the scroll element through a discharge port in
the center of the fixed scroll. This process is continuously repeated, resulting in the delivery of pulse-free
compressed air.
Variable flow technology
(VFT)
All SF
+
8-22 multi-scroll compressors are
equipped with the unique VFT control system.
The VFT system, included in the Elektronikon
®
controller, automatically starts and stops the
scroll elements to exactly match the demands
of your compressed air system. The
Elektronikon
®
control algorithm ensures that
the system pressure is kept within a very
narrow pressure band.
WorkPlace Air System™ compressors: the sound of silence
A low noise level enables the compressor to be installed close to the compressed air application, minimizing the size of the air
distribution system and reducing pressure loss and the potential for leakage. As the air treatment is completely integrated, the
installation costs are substantially reduced, making multiple compressor installations practical and financially viable. To ensure
maximum energy efficiency, Atlas Copco offers both traditional on/off regulating systems where the air demand is constant.
