ELGi AR N Series - Air Dryer
The ELGi AR N Series Direct Expansion Refrigerated Air Dryer provides a reliable solution, effectively eliminating moisture to ensure system integrity, operational efficiency, and consistent product quality.
The ELGi AR N Series Direct Expansion Refrigerated Air Dryer is a reliable, non-cycling refrigerated dryer suitable for applications requiring humidity Class 4 according to ISO 8573-1. Its advanced refrigeration system ensures consistent dew point performance (dew point of 3 degrees C) and dependable operation. As a Direct Expansion type, it does not use a thermal mass for cooling; instead, it maintains steady energy consumption while providing continuous drying efficiency under varying load conditions.
Compact, Space-Saving Design
Wall-mountable up to 67.8 m3/hr, the AR N Series fits seamlessly into tight industrial setups — ideal for workshops and small production floors.
Stainless Steel Evaporator
High-efficiency, corrosion-resistant brazed plate heat exchanger delivers long-lasting performance and consistent cooling.
Zero-Loss Auto Drain Valve
Automatically discharges condensate without air loss, improving system efficiency and reducing operational costs.
Dual-Stage Cooling System
Reduces energy usage through regenerative pre-cooling, minimizing refrigeration load and improving dryer efficiency.
Dew Point Indicator
Monitors and displays an indication of the dew point, helping operators ensure optimal compressed air quality and detect deviations quickly.
Service-Friendly Design
Accessible layout and easy-to-remove panels reduce maintenance time and effort, maximizing uptime.
Hot Gas Bypass Valve
Maintains dew point stability even under low-load conditions, protecting downstream equipment from moisture fluctuations.
Atmospheric air naturally carries humidity in the form of water vapour, which 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.
