To select a dryer, first calculate the MDC (Minimum Drying Capacity) using the formula below then select a dryer from the flow rate table above with a flow rate equal to or above the MDC. Minimum Drying Capacity = System Flow x CFMIT x CFMAT x CFMIP x CFOD CDAS HL ATEX Medium Flow Heatless Adsorption Dryers CFMIT - Correction Factor Maximum Inlet Temperature CFMAT - Correction Factor Maximum Ambient Temperature CFMIP - Correction Factor Minimum Inlet Pressure CFOD - Correction Factor Outlet Dewpoint
