NOTES
3 ） Power supply for the control operation: one-phase 220V/50Hz 4 ） If the racks are aiming to operate at different evaporating temp. or at too high or too low ambient temp., please contact us. 5 ） For an application at a temp. of ※ (i.e., -50 ° C), please contact our technicians.
1 ） The cooling capacity and input power are based on an ambient temp. of 32 ° C, the condensing temp. of 45 ° C, no liquid subcooling; and the temp. of the interstage cooling liquid for two-stage is 4.4 ° C. For example, if SIT+2.8>4.4 ° C, the temp. is SIT+5.6 ° C 2 ） Power supply for the racks: three-phase 380V/50Hz
