Vertiv GL36N12-30-B-AC10 NEMA 12 Wall-Mount Enclosure with 1000 BTU Air Conditioning
Overview
The Vertiv GL36N12-30-B-AC10 is a NEMA 12-rated, 19-inch EIA wall-mount enclosure configured at 36-inch height (19U) and 30-inch depth, factory-equipped with a 1000 BTU integrated air conditioner. Designed for industrial and commercial environments where dust and non-directional moisture are everyday realities, this enclosure is sized to house active networking, security, and control equipment in locations where a full floor-standing rack is impractical — think mid-span IDF closets, manufacturing floor junction points, or warehouse security head-end installations. The GL36N12-30-B-AC10 ships in an AC gray finish and is part of Vertiv's Vertiv wall-mount enclosure line, purpose-built for environments that demand thermal management baked in, not bolted on as an afterthought.
Key Features
- NEMA 12 Protection: NEMA 12 is the correct rating for industrial interiors — it excludes falling dirt, circulating dust, lint, and dripping or splashing water. If your equipment room shares space with a production floor, packaging line, or vehicle maintenance bay, NEMA 12 keeps contaminants out without the cost or bulk of a full outdoor-rated NEMA 4 cabinet. Not rated for outdoor or wash-down use — if that is your environment, specify accordingly.
- 19U Usable Rack Space (36-inch cabinet height): At 36 inches tall, the GL36N12-30-B-AC10 provides 19U of EIA-standard rack space — enough to mount a managed PoE switch, a mid-size NVR, a patch panel, and a UPS module without compromise. The multi-height family also includes 24-inch (12U) and 48-inch (26U) variants, so you can right-size the footprint to the actual load rather than buying headroom you won't use.
- 30-Inch Depth: The 30-inch depth accommodates full-depth 1U and 2U servers, NVRs, and deep switches that a shallower 24-inch cabinet would force you to angle or modify. Most enterprise-class NVRs and managed switches ship at 16–20 inches of chassis depth; 30 inches gives adequate cable management clearance front and rear without becoming a hallway obstruction.
- Integrated 1000 BTU Air Conditioning: Active cooling at 1000 BTU is the defining feature of this configuration. Passive convection fails when an enclosure is sealed to NEMA 12 — heat has nowhere to go without forced management. The factory-integrated AC unit maintains safe operating temperature for heat-generating equipment (switches, NVRs, power supplies) without requiring field-installation of a separate cooler or aftermarket modifications that can void enclosure ratings. For context, a single 250W heat load in a sealed NEMA 12 cabinet in a 95°F ambient environment requires roughly 855 BTU/hr of active removal — 1000 BTU provides a working margin at moderate loads.
- Airflow Flexibility (Multi-Option Family): The GL36N12-30-B-AC10 sits within a broader enclosure family that also supports fan/filter configurations, 1300 BTU AC, 2200 BTU AC, and field-installable optional fan/filter or AC units. This matters at design time: if your heat load grows — say you add a second NVR or a video analytics appliance — there is a defined upgrade path within the same enclosure family rather than a rip-and-replace.
- 19-Inch EIA Rail Compatibility: Standard 19-inch mounting rails accept the full catalog of rack-mount equipment. No adapter kits, no custom drilling — any 1U–4U device with standard rack ears drops straight in.
- Wall-Mount Form Factor: Frees floor space in closets and utility rooms that cannot accommodate a standard 4-post floor rack. Ideal for distributed network switch and NVR deployments where each building wing or floor has a small equipment node rather than a single centralized data room.
Integration and Compatibility
The GL36N12-30-B-AC10 is enclosure hardware — it does not impose restrictions on the active equipment you mount inside. Any standard 19-inch EIA rack-mount device fits: network video recorders, managed PoE switches, patch panels, KVM modules, and UPS units all integrate without modification. The NEMA 12 rating is a system-level property of the sealed cabinet; maintaining that rating in the field requires that all cable entry points be properly sealed with appropriate grommets or conduit fittings after installation. Penetrations left open will degrade the enclosure's dust and moisture exclusion regardless of the cabinet's factory rating. For deployments requiring thermal analysis before specifying, the 1000 BTU cooling capacity should be compared against the total watt-heat output of all installed equipment plus ambient temperature at the installation site — Vertiv publishes thermal sizing guidance applicable to this enclosure family.
Frequently Asked Questions
Q: What is the usable rack unit count in the GL36N12-30-B-AC10?
A: The GL36N12-30-B-AC10 is a 36-inch-tall cabinet providing 19U of EIA-standard 19-inch rack space. The same enclosure family is also available in 24-inch (12U) and 48-inch (26U) heights.
Q: Is the GL36N12-30-B-AC10 rated for outdoor installation?
A: No. The GL36N12-30-B-AC10 carries a NEMA 12 rating, which covers indoor industrial environments — protection against dust, lint, and dripping or splashing non-corrosive liquids. Outdoor use requires a NEMA 3R or NEMA 4X-rated enclosure.
Q: How much cooling does the integrated AC unit provide, and is it sufficient for a loaded NVR and PoE switch?
A: The factory-installed air conditioner in the GL36N12-30-B-AC10 is rated at 1000 BTU/hr. A single 250W device in a sealed cabinet at 95°F ambient generates roughly 850 BTU/hr of heat load, so 1000 BTU provides a reasonable margin for light-to-moderate equipment loads. If you are installing multiple high-wattage devices, calculate total heat dissipation before committing to this configuration — the enclosure family supports 1300 BTU and 2200 BTU AC variants for higher loads.
Q: What depth equipment can fit in the GL36N12-30-B-AC10?
A: The enclosure has a 30-inch cabinet depth. After accounting for rail mounting and front/rear cable management clearance, most 16- to 20-inch-deep rack-mount equipment installs without issue. Full-depth 1U servers at up to approximately 27 inches of chassis depth can typically be accommodated.
Q: Can I upgrade the cooling in this enclosure later if my heat load increases?
A: The GL36N12-30-B-AC10 enclosure family includes models with 1300 BTU and 2200 BTU AC units, as well as configurations that accept optional fan/filter or AC as field-installable options. Whether a cooling upgrade is possible in this specific configured unit depends on the mechanical provisions of the GL36N12-30-B-AC10 cabinet — consult Vertiv's product documentation for field-modification options.
Q: Does mounting this enclosure on a wall affect the NEMA 12 rating?
A: The NEMA 12 rating applies to the sealed enclosure itself. Maintaining the rating after installation requires that all cable penetrations be properly sealed — open conduit knockouts or improperly fitted cable entries will allow dust and moisture ingress regardless of the cabinet's rated protection level.
The GL36N12-30-B-AC10 is one of those enclosures that solves a specific problem cleanly: you need to house active, heat-generating equipment in an industrial interior — not a climate-controlled data center — and passive convection simply is not an option in a sealed NEMA 12 cabinet. The factory-integrated 1000 BTU air conditioner is what separates this unit from a standard wall-mount box, and it matters more than most integrators realize until they've cooked a switch in a sealed enclosure on a summer afternoon.
Technical Highlights:
- 1000 BTU Integrated Cooling: At 1000 BTU/hr of active heat removal, this unit handles a moderate equipment load — a managed PoE switch plus a mid-range NVR sits comfortably within budget in most ambient conditions up to roughly 95°F. Push beyond two high-wattage devices and you need to do the math before you order.
- 30-Inch Cabinet Depth: Most wall-mount enclosures stop at 24 inches. The 30-inch depth in this configuration means full-depth managed switches and NVRs — which routinely run 16–20 inches of chassis — install cleanly with real cable management clearance remaining, not just theoretically fitting if you angle things.
- 19U in a 36-Inch Form Factor: Nineteen rack units in a wall-mount footprint is meaningful real estate. That is a PoE switch, an NVR, a patch panel, a small UPS, and room to grow — all without touching the floor. In a warehouse IDF or a manufacturing-floor security node, that matters.
Deployment Considerations:
- NEMA 12 integrity is only as good as your cable entries. Every penetration you make after installation needs a properly rated grommet or sealed conduit fitting. Leaving a knockout open negates the rating — a common field oversight that shows up as nuisance equipment failures months later.
- The 1000 BTU cooling capacity is the primary sizing constraint. If the design calls for a video analytics appliance or a second NVR down the road, size to the 1300 BTU or 2200 BTU variant now rather than planning a cabinet replacement later.
This enclosure is the right call for distributed security camera head-end nodes in manufacturing or warehouse environments — specifically, sites where floor space is constrained, ambient conditions include circulating dust or occasional moisture, and you cannot rely on the room's HVAC to keep rack equipment cool inside a sealed cabinet.
