Vertiv GL36N12-30-B-AC13 19U NEMA 12 Wall-Mount Enclosure with 1300 BTU Air Conditioner

Overview

The Vertiv GL36N12-30-B-AC13 is a 19U (36") NEMA 12-rated wall-mount enclosure measuring 24" wide by 30" deep, factory-configured with an integrated 1300 BTU air conditioner. NEMA 12 protection means the enclosure is sealed against dust and non-pressurized water — making it appropriate for light industrial environments, factory floors, or wiring closets where a standard open rack would be exposed to airborne particulate. The 1300 BTU AC unit handles heat-generating equipment that passive ventilation cannot address, letting you consolidate active electronics in spaces without dedicated HVAC.

The GL36N12-30-B-AC13 ships in a 30" depth configuration at the 19U (36" tall) height option. Vertiv also offers this enclosure family in 24" and 48" tall variants (12U and 26U respectively), and in 24" or 30" depths with Fan/Filter or higher-capacity 1000 BTU and 2200 BTU AC cooling — select the variant that matches your equipment load and mounting space. For the 30"-deep footprint with a 1300 BTU thermal budget, this is the correct SKU.

Key Features

• NEMA 12 Enclosure: Dust-tight and drip-proof construction protects installed electronics in light industrial settings where an open rack would accumulate debris or be exposed to non-directed water spray — no separate enclosure or protective housing required.
• Integrated 1300 BTU Air Conditioner: Active cooling handles heat loads that passive fan/filter ventilation cannot manage. At 1300 BTU, this unit is sized for moderate equipment densities — network switches, small UPS units, or security appliances — without requiring external HVAC infrastructure.
• 19U / 36" Height: Nineteen rack units provides enough usable space for a compact but functional equipment stack in a wall-mount footprint, avoiding the floor-space cost of a full-height rack cabinet.
• 30" Depth: Accommodates standard 1U and 2U rack-mount equipment. Verify your deepest chassis against this dimension — equipment extending beyond 28" after connector clearance may require cable management planning.
• Wall-Mount Design: Eliminates floor-space consumption in telecom rooms, entry vestibules, or secondary wiring closets where a floor-standing cabinet is impractical.
• Configurable Cooling Options in Family: The broader GL36N12 line accepts optional Fan/Filter or AC units up to 2200 BTU, allowing thermal upgrades if equipment loads increase after initial deployment.

Frequently Asked Questions

Q: What does the NEMA 12 rating mean for the GL36N12-30-B-AC13, and where is it appropriate to use?

A: NEMA 12 indicates protection against dust, dirt, and non-pressurized dripping water. It is suitable for light industrial and commercial indoor environments — factory floors, utility rooms, and wiring closets with airborne particulate. It is not rated for outdoor use or washdown environments, which would require NEMA 4 or higher.

Q: What cooling capacity does the GL36N12-30-B-AC13 include, and how do I know if it is sufficient?

A: This unit ships with an integrated 1300 BTU air conditioner. To verify adequacy, sum the heat dissipation (in BTU/hr) of all installed equipment. If your total load exceeds 1300 BTU, consider the 2200 BTU AC variant in the same enclosure family. The enclosure also accepts optional Fan/Filter modules for supplemental airflow if needed.

Q: How many rack units does the GL36N12-30-B-AC13 provide?

A: The 36" height configuration corresponds to 19 rack units (19U) of usable mounting space. Vertiv offers the same enclosure family in 24" (12U) and 48" (26U) height variants if your equipment count requires more or less space.

Q: What is the depth of this enclosure and will it fit standard 1U rack-mount equipment?

A: The GL36N12-30-B-AC13 is configured at 30" depth. Standard 1U rack equipment (typically 16"–24" deep) fits with room for cable management. Deep 2U chassis or high-density switches with rear cable exit should be measured against the usable internal depth after accounting for the front door and rear AC unit clearance.

Q: Can the cooling configuration be changed after purchase?

A: The GL36N12 enclosure family is designed to accept optional Fan/Filter assemblies and AC units as noted in Vertiv documentation. However, the GL36N12-30-B-AC13 ships factory-configured with the 1300 BTU AC. Consult Vertiv or a pre-sales engineer before the purchase if you anticipate needing a field-upgrade path to the 2200 BTU option.

The GL36N12-30-B-AC13 is one of those SKUs that solves a specific problem well: you need a sealed, dust-protected enclosure with active cooling in a space where a floor cabinet is not viable and passive ventilation is not enough. The 1300 BTU integrated AC is the load-bearing specification here — it draws a hard line between what this unit can handle and what it cannot. Size your equipment heat load before ordering.

Technical Highlights:

• 1300 BTU Integrated AC: Factory-installed cooling eliminates the need to source and mount a separate thermal management unit. At 1300 BTU, this handles moderate-density equipment stacks — plan for roughly 380 watts of continuous heat dissipation as the practical ceiling.
• 19U (36") Height at 30" Depth: The combination of 19 rack units and 30" depth is the most common sweet spot for secondary wiring closets and remote IDF deployments — enough space for a small switch stack, patch panels, and a UPS without requiring a dedicated equipment room.
• NEMA 12 Sealing: The enclosure's dust and drip protection means you can place it in a light manufacturing cell, a loading dock control room, or a utility corridor without a secondary protective enclosure around it.

Deployment Considerations:

• Verify your wall-mount anchor points against the loaded weight of this enclosure — a 19U cabinet with active AC and a populated equipment stack can exceed 200 lbs. Structural blocking in the wall may be required depending on the installation surface.
• The 1300 BTU AC unit requires its own power feed and clearance for condenser airflow. Confirm the installation location provides adequate ambient airflow around the enclosure exterior — mounting in a sealed alcove or against adjacent equipment without clearance will reduce AC efficiency.

This enclosure is well-matched to factory floor network nodes, remote security appliance closets on manufacturing sites, or secondary IDF locations in facilities where the environment rules out open-frame racks but a full HVAC-conditioned room is not available.
