The new Atlas Copco GA range launched recently offers the most energy-efficient air compressor package with an optimum specific energy requirement. In addition, it also comes with a variable speed drive option – the new GA VSD compressor – offering the widest turndown range as comparable to any of the models available in the market.
The new GA compressor will be able to operate in the severest conditions (ambient temperatures of up to 50 degrees centigrade) and very silently (noise level of 71 dBA), which is again the best available in the market.
The Atlas Copco GA is the first oil-injected compressor in the world to integrate the water separator into the compressed air cooling system. Reducing internal pressure drops by 50 per cent, this design change contributed two per cent to overall compressor energy efficiency. This is the company’s first air compressor to offer VSD-controlled cooling fans. They adjust their speed to fluctuating cooling needs, reducing energy requirements by up to 59 per cent compared to the fixed-speed fans used by other suppliers.
The carefully optimized screw element design has resulted in a drop of five-six per cent of energy requirements as compared to the previous screw design.
“With the integration of its patented Saver Cycle Control, Atlas Copco has achieved further energy savings for its refrigerant dryers of up to 30 per cent (in normal load conditions). This technology is standard in the new GA compressors”, said Mr. R. Narayanan, Business Line Manager, Oil Free Air Division.
