The Hoffman WEATHERFLO VFD Enclosure provides heat ventilation for a VFD cooling solution that reduces heat to optimize Variable Frequency Drive Efficiency and reduce failures. Hoffman’s WEATHERFLO outdoor enclosure uses forced-air ventilation and shielded impellers allowing VFD enclosure ventilation for outdoor applications where solar heat and heavy moisture are factors. Forced-air ventilation pulls in ambient air at the enclosure bottom and exhausts hot air out the top. In colder environments, Hoffman heater products guard drives from damage due to cold starts. An adjustable thermostat (70˚-140˚F) starts the fan when needed.
