Can be offered for higher pressure and lower dew points also.Power on light.On - Off switchTower pressure guagesHighly accurate motorized cam timer.Differential pressure guage for filters.*PLC*Cycle failure indication*Sized to save heat of adsorption - minimizes purge air usage.Limited velocities through tower prevent bed fluidization - stops desiccant dusting.Large desiccant bed - ensures sufficient contact time to produce -40° C Dew point(-80°C Dew point with Molecular sieves)
