Generators provide on-site pure nitrogen
Atlas Copco's NG series of advanced nitrogen generators provide a continuous, reliable secure and independent source of on-site nitrogen generation at the lowest possible cost.
The comapny has improved energy efficiency in the new GA range by using state-of-the-art compression elements based on Atlas Copco's patented asymmetric rotor profiles, which drastically reduce volumetric losses.
By optimising oil injection, flow and temperature, the compression process is kept at the coolest possible temperature, thereby minimising thermodynamic losses, said Atlas Copco.
"However", said Paulo Pereira, GA product manager at Atlas Copco, "The most efficient compressor package goes beyond simply having an efficient screw element.

NSK shows how to handle bearings correctly
NSK has published a free, 40-page booklet 'Handling Instructions for Bearings' to help users handle and mount bearings correctly as well as maintenance and inspection.
For instance, it is also crucial to optimise all the elements around the core component.
In the development process of the new GA, we made substantial efforts to reduce all types of losses, whether flow-related, mechanical or electrical.
The latest design techniques such as Computational Fluid Dynamics (CFD) analysis were used to meet these objectives".
* Radial fans - other design features to further reduce energy consumption include radial fans with VSD regulation, high-efficiency motors and no-loss drains.
Extra energy-saving options such as an integrated energy recovery system and/or VSD for the main motor can provide even greater benefits.
IAlongside its GA compressors, Atlas Copco has also developed a new range of integrated and stand-alone refrigerant dryers.
The dryers have energy saving features such as 'Saver Cycle Control' and highly-efficient heat exchangers with minimal pressure drops.
With all these features, Atlas Copco offers its customers the 'best-in-class efficiency' for their compressed air systems.
Atlas Copco's in-house designed asymmetric screw rotor profiles assure reliability.
The rotor profiles ensure minimum wear as do carefully-selected bearings.
The robust and compact design of the GA ensures continuous operation under the most demanding conditions, such as ambient temperatures of up to 55 deg C/131 deg F and in dusty environments.
These features dramatically increase component and unit lifetime, said Atlas Copco.
* Air quality - air quality is provided by two key elements, as follows.
1 - A highly-efficient oil removal system to give minimum residual oil content in the outlet air.
2 - 'State-of-the-art' refrigerant dryers, which are available in both integrated and stand-alone versions.
Atlas Copco said it has also paid great attention to machine integration.
All components have been optimally integrated to reduce floor space and simplify connections.
The GA 'Full Feature' with integrated refrigerant dryer and air filter ensures the continuous supply of clean and dry air to extend the life of equipment, enhance system reliability and avoid costly downtime and production delays.
"This new range of GA+ oil-injected compressors is the result of continuous investments in product development and it will further strengthen our leadership in compressor technology," explained Ronnie Leten, president of Atlas Copco's Compressor Technique Business Area.
"The company's drive for energy efficiency while keeping environmental protection and climate change issues in mind has resulted in a completely new range of compressors in line with Atlas Copco's vision".
Atlas Copco said it has a long history of understanding customers' main concern, that of maximising production in a superior and highly-efficient manner.
To meet these needs, the company has concentrated on eliminating production downtime and minimising the cost of each cubic meter of compressed air produced.
Full-featured products, integrated Variable Speed Drive (VSD) and the development of customised systems are only a few examples of innovations that meet or exceed individual requirements for reliability, air quality and energy efficiency.
Chris Lybaert, divisional president, at Atlas Copco was confident.
He said: "This new GA series sets the new standards in oil injected compressors and will ensure the company's pre-eminent position in this field".
* About Atlas Copco - Atlas Copco is the leading compressed air consultant expert and helps its customers streamline and fully optimise their compressed air needs through targeted analysis and custom installations.
With the new GA range, fields as varied as the cement, glass, mining and tire manufacturing industries can benefit from unrivalled energy efficiency, reliability and air quality.
