GA7 VSD 75KW Industrial Blower Solutions , Stable Oil Injected Screw Air Compressor

ATLAS COPCO GA VSD75 OIL-INJECTED ROTARY SCREW FREQUENCY CONVERSION AIR COMPRESSOR

A New Standard In Compressor Efficiency

Inside The Intelligent, Smart GA 7 VSD

Atlas Copco’s GA 7-75 VSD 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.

VSD for more than 35% energy savings

Atlas Copco’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 Copco 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.

A step ahead in monitoring and controls
The next-generation Elektronikon® operating system offers a wide variety of control and monitoring features that allow you to increase your compressor’s efficiency and reliability. To maximize energy efficiency, the Elektronikon® controls the main drive motor and regulates system pressure withina predefined and narrow pressure band.

Dual pressure set point
Most production processes create fluctuating demands which, in turn, can create energy waste in low use periods. Using the Elektronikon®, you can manually or automatically create two different system pressure bands to optimize energy use and reduce costs.

Integrated Saver Cycles
Fan Saver Cycle reduces the energy consumption by switching off the fan in light load applications. Using an ambient sensor to monitor the required dew point suppression, the Elektronikon® starts and stops the dryer, minimizing energy use.

Week timer
An on-board clock enables timers to be set up to support any working scheme – per day, per week or completely customizable to your specific situation and needs.

Optional multiple compressor controller
The optional multiple compressor controller gives you easy, centralized control to reduce systempressure and energy consumption. Only one license is required for installations of up to 2 (EQ2i), 4 (EQ4i)or 6 (EQ6i) compressors.
