ELGi Launches AR N Series Direct Expansion Compressed Air Dryers

28 Oct 2025

Providing Compressed Air Users with a Reliable, Energy-Efficient Compressed Air Drying Solution

Waterloo, Belgium, 28 October 2025: ELGi Compressors Europe, a subsidiary of ELGi Equipments Limited, one of the world's leading air-compressor manufacturers with over 65 years of compressed air excellence, today announced the availability of its AR N Series Direct Expansion Refrigerated Compressed Air Dryers. This range is now available from 34.2 – 897 m³/hr. It addresses the critical challenge of moisture elimination in compressed air systems, delivering reliable protection against corrosion, equipment damage, and process contamination across industrial applications.

Atmospheric air naturally carries humidity that condenses into liquid under varying temperature and pressure conditions in compressed air systems. This moisture poses serious risks—corroding pipelines, damaging air-powered equipment, and introducing impurities into processes. It also compromises product quality and promotes microbial contamination, particularly in industries where compressed air purity is critical.

The ELGi AR N Series offers moisture elimination technology with its zero-loss auto drain system and dual-stage cooling process, delivering efficiency and reliability across a wide capacity range. The compact, wall-mountable design (up to 67.8 m3/hr) fits seamlessly into tight industrial setups, making it ideal for workshops and small production floors while scaling effectively for large production facilities.

"The AR N Series represents our latest development in moisture elimination technology, featuring a zero-loss auto drain valve that eliminates the compressed air wastage typically associated with conventional drain systems. Combined with the use of R513a refrigerant—the most environmentally-friendly refrigerant available today—we're delivering enhanced operational efficiency while supporting sustainability goals," said Niccolò Casini, Senior Director – Product Management – Europe.

He added, "The AR N Series incorporates cutting-edge engineering solutions including our dual-stage cooling system that reduces energy usage through regenerative pre-cooling, and a stainless steel heat exchanger that delivers exceptional durability and corrosion resistance. The compact, service-friendly design ensures maximum uptime while minimising maintenance requirements."
