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.
