The GenAir-40 is a stand alone dessicant dryer for a dew point of -40°C, controlled either by the standard 'S' range via only a start/stop switch and only showing pressures in/out on a guage or by pro 'P' range by a PLC and HMI interface. This range comes in a multiple platfroms, from the -333 single dual tower for smaller flow rates, to the 1333 four dual tower for high flow rates. The Pro range has built in settable alarms for pressure  and flow, with optional Dew point sensing and Light stack. Wake up and sleep times are standard to make sure it is ready for producton at the correct times.
