VFD

Higrid Power Corp. offers VFD solutions that go beyond the standard supply of VFD and components in a box.  Our skilled personnel understand the noise and layout issues caused by improper installation of VFD and components and ensure the wiring and layout provides for easy access of customer power and control wiring termination points.  The proper layout ensures that high temperatures components such as reactors and filters have adequate ventilation and air flow to ensure the complete internal assembly is within the manufacturers’ and CSA guidelines. Heat run testing is provided for all new VFD designs.  Repetitive VFD assemblies are all load tested at full load. All VFDs are programmed for ease of start-up on site. If actual motor data is available prior to factory testing, then the factory program does not require any parameter changes for on-site commissioning. This ensures a quick and efficient start-up after voltage verification and confirmation of proper field wiring of the VFD assembly.
