ACE Series explosionproof variable frequency drives are the only NEMA 7 VFD solution that can be safely and reliably installed in Class I, Division 1 or 2 hazardous areas, the company says. Currently available up to 60HP, the ACE Series explosionproof VFD features a NEMA 7 enclosure with patent-pending active cooling technology that allows a VFD to be housed inside the classified enclosure without the risk of overheating and failing. Expensive and complicated installations are eliminated, as there is no need to run long lines of conduit and motor cable, navigate around obstacles, or build off-site control rooms in non-hazardous areas to house VFD clusters. The ACE explosionproof VFD features a heavy duty blower inside the enclosure that creates airflow, allowing it to operate in ambient temperatures up to 50ºC.
