All models supplied with low GWP refrigerant R513A. For flows at other conditions, apply the correction factors shown below. Product Selection & Correction Factors For correct operation, compressed air dryers must be sized using for the maximum (summer) inlet temperature, maximum (summer) ambient temperature, minimum inlet pressure, required outlet dewpoint and maximum flow rate of the installation. 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 CFAT - Correction Factor Maximum Ambient Temperature Maximum Ambient Temperature °C 20 25 30 35 40 45 50 °F 68 77 86 95 104 113 122 Correction Factor - 50Hz & 60Hz 0.97 1.00 1.04 1.08 1.14 1.22 1.39 CFMIP - Correction Factor Minimum Inlet Pressure Minimum Inlet Pressure bar g 3 4 5 6 7 8 91011121314 psi g 44 58 73 87 100 116 131 145 160 174 189 203 Correction Factor - 50Hz & 60Hz 1.45 1.25 1.14 1.04 1.00 0.96 0.93 0.91 0.88 0.87 0.85 0.85 CFOD - Correction Factor Outlet Dewpoint Outlet Dewpoint °C +3 +5 +7 +10 °F +37 +41 +45 +50 Correction Factor - 50Hz & 60Hz 1.00 0.90 0.81 0.69 Flow Rates Model Pipe Size Inlet Flow Rate at 50Hz Absorbed Power at 50Hz kW Inlet Flow Rate at 60Hz Absorbed Power at 60Hz kW L/s m3/min m3/hr cfm L/s m3/min m3/hr cfm PSE 120 2" 200 12 720 424 1.32 215 13 773 455 1.7 PSE 140 2" 233 14 840 494 1.32 252 15 907 534 1.7 PSE 180 2" 300 18 1080 636 1.51 323 19 1163 685 1.9 PSE 220 21/2" 367 22 1320 777 1.79 399 24 1435 845 2.2 PSE 260 21/2" 433 26 1560 918 2.05 474 28 1708 1005 2.5 PSE 300 21/2" 500 30 1800 1059 2.62 539 32 1941 1142 3.3 PSE 350 21/2" 583 35 2100 1236 3.22 624 37 2247 1323 4.0 PSE 460 DN100 767 46 2760 1625 3.22 835 50 3005 1769 3.9 PSE 520 DN100 867 52 3120 1836 4.55 941 56 3386 1993 5.6 PSE 630 DN100 1050 63 3780 2225 4.55 1172 70 4219 2483 5.6 PSE 750 DN150 1250 75 4500 2649 6.52 1381 83 4970 2925 8.0 PSE 900 DN150 1500 90 5400 3178 9.05 1655 99 5957 3506 11.0 PSE 1200 DN150 2000 120 7200 4238 9.05 2210 133 7956 4683 11.0 PSE 1500 DN200 2500 150 9000 5297 11.17 2760 166 9935 5848 13.6 PSE 1800 DN200 3000 180 10800 6357 13.12 3281 197 11812 6952 16.4 CFIT - Correction Factor Maximum Inlet Temperature Maximum Inlet Temperature °C 30 35 40 45 50 55 60 65 °F 86 95 104 113 122 131 140 149 Correction Factor - 50Hz & 60Hz 0.81 1.00 1.23 1.49 1.82 2.44 2.63 2.94 Dryer Performance Dryer Models Dewpoint (Standard) Dewpoint (Option 1) Dewpoint (Option 2) °C °F °C °F °C °F PSE +3 +37 +7 +45 +10 +50
