EDC has completed many cooling tower motor and drive upgrade projects in which a VFD was installed where there was none. Energy rebates are generous […]
VFD RETROFIT FOR COMMERCIAL HIGH RISE – NO BMS
[vc_row][vc_column][vc_row_inner][vc_column_inner width=”1/3″][vc_single_image image=”557″ img_size=”full” style=”vc_box_shadow_border”][/vc_column_inner][vc_column_inner width=”2/3″][vc_column_text]Commercial High Rise – EDC converted three outdated pump motors to inverter duty versions and added VFDs with a self-contained pressure control loop. Cost targets and logistics prohibited adding these drives to the building management system. Therefore, a creative hardware and software approach provided a solution that previously seemed unattainable. […]
