ELGi focuses on energy efficiency

ELGi Equipments has enhanced the energy efficiency of its AB series oil-free screw air compressors, realising improvements in specific power consumption and increases in free air delivery across the range.

Contaminant free and high-quality compressed air that meets the stringent requirements of ISO 8573-1 “Class 0” standards is critical for many sensitive applications that operate across a broad range of industries such as in the food and beverages sector, the pharmaceuticals and medical sector, and the electronics sector.

Superior energy efficiency and zero mineral oil residue ensure a minimal environmental impact, thereby lowering the customers carbon footprint. Reliable, energy efficient with best-in-class life cycle cost, the AB series produce highquality air, free of microbiological contaminants, with free air delivery (FAD) from 0.82 to 15.85 m3/min.

Available from 11 to 110 kW, the water injected AB ‘Always Better’ series of oil-free screw air compressors from ELGi meet these stringent requirements, delivering certified “Class 0” high quality air in compliance with ISO 8573-1 and ISO 8573-7.

ELGi has recently enhanced the performance of the AB series models, delivering improvements in terms of both specific power consumption and free air delivery. For additional energy savings, the three larger models in the range now include a super-premium efficiency IE4 motor as standard.

ELGi’s uniquely designed airends are equipped with in-house developed η-V profile rotors which reduce pressure losses and precise rotor clearances resulting in best-in-class energy efficiency compressors with higher flow and lower specific power consumption. Compared to other water-injected units, the AB series airends run at slow speeds. The result, long bearing life, high reliability, low noise levels and reduced wear & tear.
