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 CFIT x CFAT x CFMIP x CFOD Dryer Models Dewpoint (Standard) ISO8573-1:2010 Classification (Standard) Dewpoint (Option 1) ISO8573-1:2010 Classification (Option 1) °C °F °C °F HDK-MT 15 - 70 -40 -40 Class 2.2.2 -20 -4 Class 2.3.2 HDK-MT - 350 Bar Compressed Air Dryers Outlet Dewpoint °C -20 -40 -70 °F -4 -40 -100 Correction Factor 1.00 1.00 N/A Dryer Performance Technical Data Flow Rates CFOD - Correction Factor Outlet Dewpoint CFMIP - Correction Factor Minimum Inlet Pressure CFMAT - Correction Factor Maximum Ambient Temperature CFMIT - Correction Factor Maximum Inlet Temperature
