    H o w I t Wo r k s The W dryer achieves continuous, closed loop drying by passing air simultaneous- ly through two heaters and a continuously rotating desiccant wheel. ROCESS RYING YCLE The process blower pulls moist air from the top of the drying hopper. The air pass- es through the process filter (and optional aftercooler, if installed) into the desic- cant wheel, where moisture is removed.

    C h e c k i n g f o r P r o p e r A i r F l o w This procedure is needed on W-50 through 100 models if the phase detection option was not ordered with the dryer. IMPORTANT: This step must be performed before the dryer’s air hoses are connected to the hopper or before loading material into the hopper.
