VSD for more than 35% energy savings

Atlas ’s GA Variable Speed Drive technology closely matches the air demand by automatically adjusting the motor speed. This results in energy savings of on average 35% compared to load/ unload machines.

Why choose Atlas Variable Speed Drive technology?
• On average, more than 35% energy savings with an extensive flow range (25-100% for GA 30-75 VSD)
• Integrated Elektronikon ® Touch controller controls the motor speed
• Unique NEOS inverter (for GA -75VSD)
• Oil cooled iPM motor means compressor can start/stop under full system pressure without the need to unload
• Eliminates peak current penalty during start-up.
