German KSI Filtertechnik ECOTROC adsorption dryer range for stable drying of compressed air and gases. The ATK/ATO/ATC series use cold (heatless) regeneration with flow 150–3050 m³/h, connections from 1" to DN 150, and dew points from -20 to -70 °C, at up to 16 bar g. ATW-V/ATW-S are heat- and vacuum-regenerated versions; ATM/ATT provide medical (European Pharmacopoeia) and industrial breathing air; and ATK-HP/ATC-HP high-pressure dryers operate from 50–350 bar (up to 500 bar on request). ECOMATIC microprocessor control with integrated compressor synchronization ensures an economical 10-minute cycle.
