Atlas Copco

New revolution in compressors

 

      With the revolutionary upright design, Atlas Copco's GA 7-75 VSD+ series revolutionizes the compressor industry. The series of compressors are designed by Atlas Copco in Belgium. The standard configuration is variable speed drive and built-in permanent magnet (IPM) motor. The structure is compact and the footprint is smaller. The GA 7-75 VSD+ has an average energy savings of up to 50% for stable operation under the toughest conditions. Its advanced design sets new standards for the future development of the compressor industry and reaffirms Atlas Copco's leading position in the industry.

 

 Small model, great wisdom

Innovation

Atlas Copco revolutionized the entire industry through innovations in the layout of traditional air compressors. Unlike the horizontal design that wastes space, the GA 7-75 VSD+ with vertical design

The series has a smaller footprint and saves space and work space. Its maintenance is simple, manufacturing time is shorter, and input costs are greatly reduced.

Efficient

• Reduced average power consumption by 15% compared to existing GA VSD series compressors

(SER). Efficient VSD+ series models are 50% more energy efficient than non-variable speed driven compressors

• Ultimate energy savings, FAD increases by up to 12% over the entire range

• Energy-saving fan motors up to 37 kW reduce power consumption and noise levels

• IE4 high efficiency motor (IPM), much more efficient than IE3

High reliability

• Low maintenance requirements: fewer parts and longer effective working hours

• Safe to use: GA 7-75 VSD+ field test through various conditions

• With unique experience and technology, Atlas Copco combines proven expertise with existing components

perfect

• Beautiful and innovative design

• (VSD+) inverter control standard supply, also built-in dryer

VSD+ series saves up to 50% on average

The Atlas Copco GA VSD+ series of compressors automatically adjust the motor speed to precisely meet the customer's gas needs. Incorporating innovative permanent magnet (IPM) motors for an average energy savings of up to 50%

Life cycle costs can be saved by an average of 37%. The permanent magnet motors used in the VSD+ series were independently developed by Atlas Copco in Belgium.

Why choose Atlas Copco variable speed technology?

When the demand for gas is drastically changed (20%-100%), the average energy saving is 50%.

Elektronikon® color screen controller controls motor and frequency converter

No idling and emptying waste

The compressor can be started/stopped at full pressure without waste of unloading

No peak current is activated, avoiding possible fines

Reduce system working pressure and reduce system leakage

The air demand in most production environments fluctuates violently every day, every week, every month. Through in-depth investigations and measurements, most of the compressed air demand has varying degrees of fluctuations.
