VSD: Driving down your energy costs
Over 70% of a compressor’s life cycle cost is taken up by the energy it consumes. Moreover, the generation
of compressed air can account for more than 40% of a plant’s total electricity bill. Atlas Copco was the
first compressor manufacturer to introduce compressors with integrated Variable Speed Drive (VSD). With
over 20 years of design and manufacturing experience our VSD technology has reached new heights of
energy savings and reliability. VSD technology reduces energy consumption in systems that have varying
air demand patterns.This reduction in energy consumption not only reduces your energy consumption but
also your carbon footprint to help protect the environment for generations to come.
Why VSD technology?
In almost every production environment, air demand fluctuates depending on different factors (time of the day, week or even month).
Extensive measurements and studies of compressed air demand profiles show that many compressors have substantial variations in
air demand. Only 8% of all installations have a more stable air demand.Tests prove that, even in this case, VSD compressors
save energy.
Profile 1
• 64% of all installations.
• Factory working 24 hrs/day: low
demand at night & high demand
during the day.
Profile 2.
• 28% of all installations.
• Factory working 2 shifts/day,
no weekend work: erratically
varying air demand.
Profile 3.
• 8% of all installations.
• Factory working 2 shifts/day,
no weekend work: typical ‘fixed’
speed application.
