Vertiv NEMA 12K WM 12UX24X24 1000 BTU AC Gray - GL24N12-24-B-AC10

Vertiv GL24N12-24-B-AC10 NEMA 12 Wall-Mount Enclosure with 1000 BTU AC

The Vertiv GL24N12-24-B-AC10 is a 12U wall-mount enclosure built to NEMA 12 standards — designed for industrial and commercial environments where airborne dust and non-directional dripping water are real concerns. At 24 inches wide by 24 inches deep, it fits compact networking, security control, or edge-compute equipment in tight spaces without sacrificing thermal management: the unit ships with an integrated 1000 BTU air conditioner, so heat-generating equipment stays within operating range even in unconditioned mechanical rooms or factory floors.

Overview

Wall-mount enclosures in the Vertiv enclosure line exist in multiple height configurations — 12U (24"), 19U (36"), and 26U (48") — but the GL24N12-24-B-AC10 locks in at the 12U height with a 24-inch depth and the 1000 BTU AC cooling option. That combination targets deployments where rack space is limited but thermal load exceeds what passive or fan/filter solutions can handle. If you're housing a mix of PoE switches, an NVR, and access control hardware in a single wall-mount cabinet in a non-air-conditioned space, 1000 BTU of active cooling keeps inlet temperatures from creeping into the warning range during summer months. The gray finish is standard for wall-mount enclosures in industrial settings and won't stand out in utility or mechanical rooms.

Key Features

• NEMA 12 Rating: protects against dust, dirt, and non-directional dripping water — appropriate for factory floors, mechanical rooms, and industrial corridors where a standard NEMA 1 enclosure would accumulate contaminants on sensitive equipment.
• 1000 BTU Integrated Air Conditioner: active cooling eliminates dependence on ambient room temperature. For a 12U cabinet running PoE switches and recording hardware continuously, passive fan/filter solutions fail once room temps exceed equipment inlet specs — this unit removes that constraint.
• 12U (24") Height: accommodates a practical mix of 1U and 2U gear — typically 4–6 devices — without requiring floor space. Wall-mounting also puts equipment at accessible height for maintenance without bending down to a floor-standing rack.
• 24" x 24" Footprint: the 24-inch depth handles most 1U switches, NVRs, and patch panels. Shallower 18-inch-depth alternatives won't fit standard-depth rack equipment; this unit does without wasted space.
• Configurable Cooling Options: the GL product family supports Fan/Filter, 1000 BTU AC, 1300 BTU AC, and 2200 BTU AC variants — so if your thermal load grows, a higher-BTU sibling exists in the same enclosure family rather than requiring a full cabinet replacement.

Integration & Compatibility

This enclosure is compatible with standard 19-inch rack-mount equipment. The 12U height and 24-inch depth suit typical network switches, NVRs, and access control panels used in commercial security infrastructure. For higher-density deployments or deeper equipment, the 30-inch depth variant and 19U/26U height options within the Vertiv GL family address those requirements. Pair with a UPS or power distribution unit rack-mounted inside for protected power delivery to critical equipment in the enclosure.

Frequently Asked Questions

Q: What cooling capacity does the GL24N12-24-B-AC10 include?

A: The GL24N12-24-B-AC10 includes an integrated 1000 BTU air conditioner as its active cooling solution, suitable for moderate thermal loads in unconditioned spaces.

Q: What is the rack unit capacity of the GL24N12-24-B-AC10?

A: It is a 12U enclosure (24 inches in height), accommodating standard 19-inch rack-mount equipment up to that height.

Q: What depth equipment can the GL24N12-24-B-AC10 accommodate?

A: The enclosure has a 24-inch depth, which fits the majority of standard-depth 1U and 2U rack-mount switches, NVRs, and similar devices.

Q: What NEMA rating does the GL24N12-24-B-AC10 carry?

A: It is rated NEMA 12, providing protection against dust, dirt, and non-directional dripping water — appropriate for industrial and commercial environments.

Q: Are there higher-BTU or larger enclosure options in the same family?

A: Yes. The Vertiv GL enclosure family includes 1300 BTU AC and 2200 BTU AC cooling variants, as well as 19U and 26U height options and 30-inch depth configurations, allowing you to scale within the same product line.

Karl Wilson

The GL24N12-24-B-AC10 is a deployment-specific answer to a common field problem: you need 12U of wall-mount rack space in a room that doesn't have HVAC, and passive fan/filter cooling won't cut it once ambient temps rise. The 1000 BTU integrated AC unit is sized for moderate continuous loads — think a managed PoE switch, a 16-channel NVR, and a small access control panel running 24/7 in a mechanical or utility room.

Technical Highlights:

• 1000 BTU Active Cooling: removes up to ~293 watts of heat continuously — sufficient for most 12U security equipment buildouts drawing 150–250W aggregate, keeping inlet temps within spec regardless of room temperature.
• NEMA 12 Enclosure: the dust and drip protection matters in manufacturing, warehouse, and utility environments where a standard open-frame or NEMA 1 cabinet accumulates debris on equipment within months.
• 12U × 24" Depth: the depth is the deciding factor for compatibility — 24 inches clears standard-depth managed switches and most 1U NVRs without the clearance issues you get in shallower enclosures.

Deployment Considerations:

• Verify wall-mount load rating before installation — a fully loaded 12U cabinet with an integrated AC unit carries significant weight; structural backing behind drywall is typically required.
• The 1000 BTU rating covers moderate loads; if you're planning high-density PoE switching (e.g., a 48-port PoE+ switch at near-full load) in this cabinet, model your thermal load before committing — the 1300 BTU or 2200 BTU variants in the same GL family exist for higher-draw buildouts.

This unit fits well in warehouse security closets, factory-floor network nodes, and utility rooms serving multi-camera NVR deployments — any site where wall space is available, floor space is not, and ambient temperature control is unreliable.
