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 Flow Rates Model Pipe Size Inlet Flow Rate L/s m3/min m3/hr cfm KE-MT 120 DN 50 333 20 1200 706 KE-MT 150 DN 65 430 26 1550 912 KE-MT 200 DN 65 556 33 2000 1177 KE-MT 250 DN 80 695 42 2500 1472 KE-MT 300 DN 80 833 50 3000 1766 KE-MT 380 DN 100 1056 63 3800 2237 KE-MT 500 DN 100 1347 81 4850 2855 KE-MT 600 DN 125 1695 102 6100 3590 Dryer Performance Dryer Models Dewpoint (Standard) ISO8573-1:2010 Classification (Standard) Dewpoint (Option 1) ISO8573-1:2010 Classification (Option 1) Dewpoint (Option 2) ISO8573-1:2010 Classification (Option 2) °C °F °C °F °C °F KE-MT 120 - 600 -40 -40 Class 2.2.2 -70 -100 Class 2.1.2 -20 -4 Class 2.3.2 ISO8573-1 Classifications when used with Parker OIL-X pre/post filtration. Stated flows are for operation at 7 bar (g) (102 psi g) with reference to 20°C, 1 bar (a), 0% relative water vapour pressure. For flows at other pressures, apply the correction factors shown below. Dryers for smaller flows are available on request. Carbon Steel Twin Tower Compressed Air Dryers
