VFD Division 2 NEMA 4X panels provide a purged, stainless‑steel enclosure solution for operating drives and related equipment in classified areas. These packages use a Z‑purge system to achieve Division 2 or Zone 2 suitability while offering corrosion‑resistant construction for demanding outdoor environments. Control Innovations supplies custom Division 2 NEMA 4X VFD panels designed for reliable operation, remote accessibility, and compliance with Canadian and international standards.
A VFD Division 2 NEMA 4X panel provides variable‑speed motor control in hazardous locations using a purged, stainless‑steel enclosure. The Z‑purge system maintains a safe internal environment, allowing general‑purpose components to be used while meeting Division 2 or Zone 2 requirements.
Key Features
Control Innovations Division 2 NEMA 4X VFD panels typically include:
- Stainless‑steel NEMA 4X enclosure for corrosion‑resistant outdoor use
- Z‑purge system for Division 2 or Zone 2 classification
- Stainless‑steel, Division‑rated air conditioners or heat exchangers for cooling
- Ability to use general‑purpose relays, switches, thermostats, contactors, breakers, and disconnects inside the purged enclosure
- VFD of your choice with optional harmonic mitigation (reactors, dV/dt filters, matrix filters)
- Division 2‑rated HMI when keypad mounting is not possible
- Door‑mounted operators and pilot lights for essential functions
- Optional communication interfaces (Ethernet, Modbus, BACnet, LonWorks)
This creates a durable, compliant, and field‑ready drive system for corrosive or outdoor hazardous locations.
