Atlas Controls Reduce Compressed-Air Costs

Atlas Copco Compressors has introduced the next generation in compressor controls across its oil-injected screw compressor range 11-90 kW GA/GA+/GA VSD. The new fifth-generation Elektronikon graphical-display controller and the integrated Energy Saving (ES) Systems ES4/6i increase compressed-air efficiency, resulting in lower operating costs. In addition, free online visualisation enables remote monitoring, allowing for anticipation of operating and maintenance needs.

Atlas has expanded the Energy Saving (ES) System to simultaneously control, with the ES6i, up to six variable-speed drives or fixed-speed compressors. The Elektronikon graphical-display controller is a colour display, housed on the compressor, that shows several compressor and dryer parameters while built-in algorithms automatically implement energy-saving cycles for fan and dryer. Additional features such as dual-pressure band and timer-based controls enable Atlas Copco to maximise energy savings by matching the operating pressure to air demand.

The optionally integrated Energy Saving Control System, ES6i, is capable of regulating and sequencing up to six variable or fixed-speed compressors. It can also optimise the customer's installation by reducing the overall working pressure-band of each compressor to meet the varying air demand. The possibility to manage up to six variable-speed compressors with one integrated controller (up to four compressors with the ES4i) reduces installation costs while minimising energy and maintenance costs through reduced pressure band.

Depending on the compressor configuration and air demand, the improved ES control system can reduce yearly running costs by up to 30 per cent. This Elektronikon features a user-friendly interface that keeps the user informed about the operating condition of the unit. The hardware innovations include a new human machine interface with durable keyboard and a user-friendly navigation system. The Elektronikon graphical display controller has a high-quality 3.5in colour display. The built-in web-server technology uses Ethernet communication to provide instant online compressor-status visualisation.

The graphic visualisation provides service intervals in real time and displays a graphical service plan assisting in preventive maintenance. Customers can select one of 32 languages while all registered data is stored for later use. The optional AIRConnect allows for remote or local monitoring (through the phone or wireless-internet connection) for additional on or off-line readings. The Atlas Copco oil-injected screw compressor features efficient components (compressor element, coolers, motor) that provide premium performance in free-air delivery and specific energy requirements. Coupled with superior controls, overall efficiency is increased further by complete system optimisation, which results in reduced operating costs.
