Ingersoll Rand Desiccant Air Dryers 5-14,900 m³/hr

Ingersoll Rand desiccant air dryers cover flows from 5 to 14,900 m³/hr in three ranges: heatless modular dryers (DA5IM to DA300IM), heatless twin tower dryers (D160ILA to D8500ILA, 2.8 to 55.9 m³/min) and heated blower dryers (D500IBA to D14900IBA, 8.9 to 248.6 m³/min). All are rated for continuous 10 bar g operation and run at 50 Hz as standard.

Heatless dryers deliver a constant -40 °C or -70 °C pressure dew point and use 15% of the compressed air for regeneration. Heated blower dryers deliver -40 °C and use 0% purge air, regenerating the desiccant with a centrifugal blower and high-performance heater instead, which is why they suit larger installations where energy cost matters most. The Energy Management System (EMS) holds a constant dew point while matching regeneration to the actual load; it is standard on heated blower dryers and optional on heatless models.

A digital microprocessor controller monitors the dryer continuously, matches dryer control to the load and unload state of the compressor and is Modbus compatible, with a 7 inch display on heated blower models. High efficiency pre-filters remove oil aerosol down to 0.01 mg/m³ and heavy duty after-filters remove particles down to 1 micron. Heated blower dryers come as standard with an IP54 enclosure, soft starter, non-acidic desiccant, silencing muffler, butterfly valves, safety relief valve and humidity sensor, with IP65 enclosures, 60 Hz supply and pneumatic options available.
