The three-phase version of our patented Generator Start Inhibit Device (U.S. Patent No. 12,695,402), designed for sites running three-phase power infrastructure. Using IoT-enabled air quality inhibit (AQI) logic, it suppresses non-emergency generator exercise cycles during air quality alerts across all three phases — while automatically allowing emergency generator operation when a power outage or brownout is detected. Protects DAC systems and connected equipment while keeping operators in compliance with environmental regulations, no site visit required.
