| Advanced C1 Controls |
A powerful controller monitors and controls each D-Series4 high pressure desiccant air dryer. The system monitors multiple inputs, showing pertinent data on the two line clear text display and controlling the fully automated drying and regeneration cycles. Input is via three buttons on the front of the NEMA-4X corrosion resistant enclosure. An energy saving compressor synchronization contact is provided to stop the dryer from cycling when the compressor is not operating. ES Energy Saving Option - The optional “ES” dew point demand system uses a reliable precision hygrometer to continually monitor the outlet dew point and extend the cycle for maximum energy savings. Includes real time outlet dew point indication on the panel, a 4-20 mA signal for remote monitoring and a high dew point alarm. |

| How It Works |
The advanced nano D-Series4 high pressure compressed air dryers use the pressure swing adsorption principle to efficiently dry compressed air. Incoming wet air passes through a high efficiency coalescing filter which removes particulate and aerosols down to 0.01 micron with greater than 99.9999% efficiency. The air is then directed to one of the two media vessels where water vapor is adsorbed by a two layer desiccant bed. The dry air then passes through the outlet check valve and a 1 micron particulate after filter to remove any media dust it may have collected. Simultaneously, a small amount of the dry air (approximately 5% of the rated flow) is expanded to atmospheric pressure across an orifice and passed backwards through the off line desiccant bed for regeneration. Regeneration air is exhausted to atmosphere through a silencer. The entire dryer operation is controlled by the advanced C1 controller which switches the flow from one vessel to the other every 10 minutes or as directed by the optional dew point demand system. |
