Hazardous location

We don't build this one — but we sell what does.

Hazardous-location / explosion-proof rating required — VoltAire units are NEMA 4/4X only and carry no Class I/II Division rating; 460V supply — VoltAire units are 115VAC or 230VAC single phase.

Why it doesn’t cross over

  • 460V supply

    VoltAire builds 115VAC and 230VAC single phase today. A 460V line is in development — the design is finished and UL listing is the remaining step.

  • Hazardous-location rating

    VoltAire units are NEMA 4 / 4X and carry no Class I or Class II Division listing. That is a different certification path, not an option we can add.

We can still help with this one

Explosion-proof cooling is a different product line, and we sell it. Purpose-built Class I Div 1/2 equipment rather than a NEMA enclosure cooler — same people, same phone number.

Tell us the enclosure and the area classification and we’ll come back with what fits.
