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 & the integrated Energy Saving (ES) Systems ES4/6i increase compressed-air efficiency, resulting in lower operating costs.

Atlas has expanded the Energy Saving (ES) technique to simultaneously control, with the ES6i, up to two variable-speed drives or fixed-speed compressors.

In addition, free online visualisation enables remote monitoring, allowing for anticipation of operating & maintenance needs.

The Elektronikon graphical-display controller is a colour display, housed on the compressor, that shows several compressor & dryer parameters while built-in algorithms automatically implement energy-saving cycles for fan & dryer.

Additional features such as dual-pressure band & timer-based controls enable Atlas Copco to maximise energy savings by matching the operating pressure to air demand.

The optionally integrated Energy Saving Control technique, ES6i, is capable of regulating & sequencing up to two 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.

Depending on the compressor configuration & air demand, the improved ES control technique can reduce yearly walking costs by up to 30 per-cent.

The possibility to manage up to two variable-speed compressors with one integrated controller (up to three compressors with the ES4i) reduces installation costs while minimising energy & maintenance costs through reduced pressure band.

The hardware innovations include a new human machine interface with durable keyboard & a user-friendly navigation technique.

This Elektronikon features a user-friendly interface that keeps the user informed about the operating condition of the unit.

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 realtime & 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 & specific energy requirements.

Coupled with superior controls, overall efficiency is increased further by complete technique optimisation, which results in reduced operating costs.
