Cooper Crouse-Hinds’ ACE Series Explosionproof Variable Frequency Drives (VFD) are a NEMA 7 VFD solution that can be installed in Class I, Division 1 or 2 hazardous areas. VFDs are already widely used to optimize the speed of motors controlling process equipment, but until now they have not been used inside classified enclosures because heat generated by the VFD inside the enclosure causes it to fail. Instead, VFDs are installed in control rooms outside of the hazardous area, resulting in expensive and impractical installations. The explosionproof VFD from Cooper Crouse-Hinds provides a solution to the challenge of using a VFD in a hazardous environment.
