variable speed drive air compressor

Atlas Copco has turned the compressed air industry on its head by redesigning the conventional layout of a typical air compressor. Instead of the normal space-taking horizontal design, the new GA 7-75 VSD+ has an upright, vertical, low footprint layout. This saves valuable floor and work space, eases maintenance access, accelerates manufacturing time, and reduces the total cost of ownership for all customers. • On average 15% lower Specific Energy Requirement (SER) than the current GA VSD models. Eco-efficient VSD+ reduces energy consumption by on average 50% compared to the current idling models. • On top of energy savings, Free Air Delivery (FAD) increase of up to 12% over the range. • Efficient fan motor below 37 kW (ERP 2015) reduces electricity consumption and noise levels. • IE4 motor efficiency (iPM), outperforming IE3 efficiency levels. • On average 50% energy savings with an extensive flow range (20-100%). • Integrated Elektronikon® Graphic controller controls the motor speed and high efficiency frequency inverter. • No wasted idling times or blow-off losses during operation. • Compressor can start/stop under full system pressure without the need to unload with special VSD+ motor. • Eliminates peak current penalty during start-up. • Minimizes system leakage due to a lower system pressure.

Atlas Copco’s GA 7-75 VSD iPM compressors feature smart drive and intelligent control for unprecedented reliability and efficiency. Variable Speed Drive is integrated as standard, along with an Integrated Permanent Magnet motor and a unique air compressor inverter. As a result, the GA 7-75 VSD reduces energy consumption by an average of at least 35%, setting a new benchmark for cost savings and sustainable performance in the compressor industry. These compressors are equipped with a leakage-free drivetrain designed by Atlas Copco. It relies on a patented Vaccum Ejector System (VES), which avoids oil leakage in oil-injected compressors. • On average 10% lower Specific Energy Requirement (SER) than fixed speed compressors. Energy consumption is typically reduced by at least 35% compared to an idling compressor. • Minimized efficiency losses through a direct drive with an permanent magnet motor equalizing IE4. • Optimized inlet flow at air-end through use of sentinel Valve to minimize pressure and air loss. • Low maintenance: Vacuum Ejector System (VES) creates a leakage-free system for GA 30 -75 VSD. • Proven durability with modular design to ensure maximum use of parts. • W-fin cooler for dependable performance in harsh environments.
