VFD s can be provided either in a free standing NEMA 3R outdoor enclosure, OR, in what’s termed an “E-House.”EMA can provide almost any drive in a NEMA 3R outdoor configuration, and in partnership with Lectrus in Chattanooga can provide a VFD and its affiliated switchgear in an E-House configuration. Medium Voltage VFD s, due to their size, are often better housed in an E-House, although Toshiba does sell their medium voltage VFD in a Nema 3R configuration. (EMA both sells and services Toshiba medium voltage VFDs)
A single low voltage VFD is often most cost efficient to provide in a NEMA 3R configuration, but if you have more than one, a VFD E-House may be a better option.
In addition, if you need the units to have positive pressure for a hazardous environment, an E-House is often a better solution.
Regardless, if you have a VFD application that needs an outdoor enclosure, both low and medium voltage, EMA is who you should call first.
