VFD HARMONIC MITIGATION/IEEE-519
Drives can be a nasty source of electrical noise if not handled properly. The IEEE-519 specification presents guidelines for acceptable harmonic levels based on an installation’s electrical load and utility conditions. EDC has extensive knowledge and experience with projects in which reducing harmonics is key and can even provide pre and post-installation studies. Ask about […]
WASTE WATER TREATMENT
A waste water treatment facility for a NJ municipality needed a retrofit for an outdated 125 hp soft start, VFD and bypass circuitry. EDC manufactured a pre-assembled controls panel and finished the wiring and installation on site with zero down time. The new controls decreased the foot print, improved reliability and saved energy.
COOLING TOWER VFD RETROFITS
Do you have a cooling tower with two-speed motors or a system that uses a high and a low HP motor for various demand conditions? 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 and help to reduce payback […]
VFD RETROFIT FOR COMMERCIAL HIGH RISE – NO BMS
Commercial High Rise – EDC converted three outdated pump motors to inverter duty versions and added VFDs with a self-contained pressure control loop.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. Local utility rebates and energy […]
