Atlas Copco has added three new models to its range of oil-injected rotary screw compressors to give larger industrial air users a 20% average improvement in free air delivery and energy savings of up to 35%. Complementing the existing fixed speed GA160+-315 range, the new VSD additions comprise the GA200VSD, GA250VSD and an upgraded version of the GA315VSD, with three different pressure variants from 8.5 to 14 bar developed to match operators’ needs.
The adoption of smart design principles has improved airflow, measured as free air delivered (FAD). Operators can now select smaller compressors for the same applications, thus saving money and energy. Atlas Copco’s progressive improvements and engineering breakthroughs − such as the new generation asymmetric compression element incorporated in these machines − has increased FAD by an average of 20% across the range.
With the use of variable speed drive technology, energy savings of up to 35% are achievable by automatically adjusting the motor speed to match the air demand. Additionally, the optional energy recovery system can recoup up to 75% of the compressor’s shaft power as hot water, which can be re-used for process operations or premises heating applications.
Specific Energy Requirement (SER) is a measure of how efficiently electrical power is used to produce your compressed air. The new compressors’ combination of a high efficiency IP55 motor and optimised, gear-driven transmission system contributes to increased energy efficiency and results in an overall improvement in SER of 11% on comparable compressors.
The compressors are available in a standard pack or as full feature, air-cooled or water-cooled versions. They are designed for standard operating conditions of up to 46°C/115°F. With integrated dryer, the full feature GA FF models provide dry, compressed air at a pressure dewpoint of +3°C/37°F while ensuring the lowest pressure drop and minimal installation costs.
The new range has been designed from the outset for easy installation and serviceability. The compact design, now with a 5% smaller footprint than previous models, includes internal piping, coolers, motor, lubrication and control system supplied as a ready-to-use, plug and run package. To help reduce service costs to the minimum, all components and consumables offer a long operational lifetime of up to 8,000 hours and are easily and safely accessible via large opening doors.
All models incorporate the Elektronikon Mk5 Graphic Plus controller for total operational control and remote online monitoring through simple ethernet connection. This enables internet-based visualisation via the compressor’s user-friendly 5.7inch colour display, and also helps to provide full system protection with service scheduling and built-in safety alarms. The controller connects to SmartLink, Atlas Copco’s compressor data monitoring programme, which intelligently gathers, compares and analyses data to help compressed air users increase maintenance and service efficiency.
In parallel with the new GA range launch is the introduction of a larger version of Atlas Copco’s UD+ coalescing filter. The UD+ replaces the oil aerosol and solid particles filters incorporating innovative Nautilus two-in-one filter technology, which is designed for higher energy efficiency without compromise on performance or reliability.
In classic filter construction pleated media are used to reduce pressure drop but this method increases the risk of cracking and oil carry-over resulting in poor air quality. The Nautilus filter technology incorporated into the UD+ concept eliminates the risk of cracks in the filter media because they are wrapped around the stainless steel filter core. Less dense filter media used in Nautilus filter technology ensures much easier passage of the air leading to significant pressure drop reduction, 40% lower than a combination of a conventional two stage oil aerosol and solid particles filters but with the same level of filtration efficiency.
The net effect is increased energy efficiency with lower running costs. The two-in-one filtration concept reduces installation space and complexity, making UD+ filters particularly suitable for applications where space is at a premium.
