Note: These pumps can operate with glycol water (mono-ethylene glycol), although with a reduction of the available pressure (due to the flow variation with glycol water). Consult the correction coefficients in the chapter “Operation with glycol water”. 40 3.173 30 3.175 3.174 3.172 3.171 20 2 1 3 Number of pump 4 5 6 7 8 9 10 15 20 Flow (m3/h) 3.171 3.172 3.173 3.174 3.175 3.229 0,37 0,55 0,75 0,9 1,5 0,55 Motor output kW Maximum absorbed current A 1,4 2,0 2,3 2,7 4,0 2,0 Minimum water flow m3/h 1,2 1,2 1,2 3,0 4,8 3,0 Maximum pressure (m.w.c) 20,7 28,0 30,3 29,5 31,6 20,6 Maximum water flow m /h 5,4 4,8 6,6 9,6 15,0 9,6 Minimum pressure (m.w.c) 15,0 20,5 19,5 19,5 23,0 13,7 C A R R I E R 3 2 0 1 6 / 2 0 1 7 CONTROLS 10 AIR TREATMENT 3.229 447
