Focus on: Compressed Air Process, Controls & Plant line, it also helps to protect the environment. New technology New technology, such as Atlas Copco’s latest compact GA VSD+ compressors, eliminate most challenges associated with the original VSD designs, starting with the performance of the integral, in-house designed Neos compact inverter unit, which contributes to an overall 8% improvement in Specific Energy Requirement (SER) over that of any comparable compressors. The principal innovation of the VSD+ design is in the close-coupled drive train ? the combination of a high-efficiency motor and technically advanced, asymmetric compression element. The IP55 motor was designed in- house with special attention to cooling requirements and efficiency. With no coupling or gears between the motor and screw element the compressors are quiet, 73dB (A) in operation and extremely energy-efficient in performance. The vertical aspect drive train of the VSD+ machines is a closed circuit in which both the motor and the element is cooled with oil, thus contributing additional energy savings. Added to this is a 6% increase in free air delivery for improved efficiency and performance, plus a reduction in the compressors’ total lifecycle costs in the order of 37%. Smart communication The importance of connectivity with advanced monitoring and control systems is an area that is becoming increasingly important because it not only makes the compressor easier to operate but also increases both efficiency and reliability. For example, Atlas Copco’s VSD+ compressors come with a high-tech Elektronikon Touch controller and the optional Smartlink monitoring system. In combination, these features make it possible to optimise a compressor remotely from just about anywhere on the planet using only a computer or even a mobile device. That makes compressed air production even more efficient (and greener). In addition, the system anticipates potential issues and alerts the operator before they become problems, which further increases uptime. Technology of the future The entire manufacturing sector is in the midst of a major technological revolution. The move toward connectivity and digitalisation in the era of Industry 4.0 is now a reality rather than a distant future. As such, manufacturers are increasingly using OPC UA communication technology, which is the common language that allows equipment to “speak” with each other. It is technology that ensures that an operation runs smoothly by making sure that every item of equipment can effortlessly communicate with every other device. Because a compressor is too important not to be part of a networked production operation, Atlas Copco for example, has therefore released its first series of compressors that speak this universal language and has assured compressor users that in the future it will be possible to install this technology retroactively and enjoy all its benefits. The upsides to being at the forefront of this technology are obvious: The possibilities that the new connectivity offers will completely change manufacturing as we know it. In the world of compressed air, it is the biggest thing since VSD compressors redefined energy efficiency and changed the industry forever.
