ELGi unveiled, at Hannover Messe, its portfolio of oil-free, oil-lubricated compressors, and accessories designed to address European customers' needs for low life cycle cost compressed air solutions. On display were ELGi’s oil-free screw air compressor with an integrated heat recovery system and the improved efficiency oil-lubricated screw compressor with a new permanent magnet synchronous motor. ELGi’s first two-stage oil-lubricated screw air compressor enabling industry-leading low total cost of ownership and increased reliability.
Delivering pure air
While air compressors consume approximately 10% of Europe’s overall industrial electrical energy demand, over 70% of a compressor’s lifecycle costs are made up by the energy used during operations. So there is a big potential in driving down the total cost of ownership with energy efficiency and process improvements. One of the introduced highlights was the OF90-160 Range, compliant with class zero ISO 8573-1 air purity standards. The two-stage dry screw and water-cooled oil-free air compressors are available in fixed and variable speed options with a nominal power of 90 to 160kW. The range can also be equipped with an integrated and stand-alone Heat Recovery System (HRS), recovering up to 90% of the heat generated during the compression process, and has improved performance within the 4.5 – 10 bar -operating range. These units can also be installed outdoors with protection kits.
Another important focus was on ELGi’s “Air~Alert”, the IoT-based Machine Monitoring System. Enabling data analytics and real-time monitoring of air compressor parameters, ELGi's Air~Alert is a data transmission and analysis service that monitors a compressor's critical parameters to minimize downtime and maximize efficiency. Predictive alerts are a step closer to prognostics for detecting and preventing failures. With Air~Alert, customers worldwide are assured of highly accurate advanced predictive machine downtime alerts and minimized unplanned downtime.
