VoltAire Product Line
Enclosure Cooling Products
Three ways to protect the electronics inside a sealed cabinet — active air conditioning, passive heat exchange, and positive pressurization. All UL listed, NEMA rated, and made in the USA.
Air Conditioners
1,000 – 19,000 BTUh • 115V · 230V · 48VDC
Active, compressor-based cooling for sealed NEMA 4/4X enclosures. Bolt-for-bolt and adapter-fit replacements for McLean, Hoffman, Pentair & nVent.
Heat Exchangers
15 – 90 W/°F • 48VDC · 115V · 230V
Passive, closed-loop air-to-air cooling — no refrigerant, no compressor, zero ingress. For enclosures that generate heat but can't tolerate outside air.
Pressurization Units
300 – 1,600 CFM • −40°F to 131°F
Maintain positive building pressure to keep dust, moisture, and contaminants out — from a bolt-on module for Bard HVAC systems to a standalone PLC-controlled unit.
Running on DC Plant Power?
Native 48VDC cooling — no inverter required
Air conditioners and heat exchangers that connect directly to the −48V plant. No efficiency loss, no extra failure point.
Replacing an existing unit?
Look up any McLean, Hoffman, Pentair, or nVent model — we’ll show you the VoltAire unit that bolts in its place.
