Airrex HSC-12R Portable Spot Cooler 12000 BTU 1 Ton R-454B Refrigerant 115V Single Phase 5 Inch Cold Air Nozzle ETL Listed
Airrex HSC-12R Portable Spot Cooler — 12,000 BTU, R-454B, 115V
The Airrex HSC-12R is a compact, 1-ton portable spot cooler engineered for directed cooling in small to mid-sized commercial spaces. It delivers 12,000 BTU of cooling through a 5-inch front cold air nozzle, with a 12-inch top warm air exhaust to vent heat out of the work zone. Runs on a standard 115V outlet (NEMA 5-15 plug, 15-amp fuse) — no special wiring needed. The HSC-12R uses modern, low-GWP R-454B refrigerant, includes a 4-gallon condensate tank with auto shut-off, and ships ETL listed for commercial use.
Key Features
Engineered for dependable performance with the features that matter most.
12,000 BTU Directed Cooling
Targeted 12,000 BTU spot cooling through a 5" front cold air nozzle — aim cold air exactly where workers, equipment, or guests need relief from the heat.
Eco-Friendly R-454B Refrigerant
Modern low-GWP R-454B refrigerant — meets current environmental standards while delivering reliable cooling performance.
Plug-and-Play 115V Power
Standard 115V single-phase, NEMA 5-15 plug, 15-amp fuse — no special wiring, no electrical upgrades. Plug into any standard outlet and run.
5" Cold Air + 12" Warm Exhaust
Front-mounted 5" diameter cold air nozzle (1) for directed cooling, plus a 12" diameter top flange for warm air exhaust with optional ducting.
4-Gal Tank with Auto Shut-Off
Built-in 4-gallon condensate tank with automatic full-tank shut-off and tank position detector. Optional auto pump for continuous drainage.
ETL Listed & Protected
ETL listed with high/low-pressure switches, 3-minute compressor delay timer, thermostat protector, and fan motor protection.
Note: The HSC-12R operates in ambient temperatures of 68-113°F. For enclosed work zones, route the 12" warm air exhaust outdoors or above the ceiling (optional warm air duct kit available with 8 ft of 12" ducting and 2'x2' ceiling flange). A fresh-air supply may be needed in tightly enclosed spaces for optimal performance.
Ideal Applications
Compact, outlet-ready, and directed — the HSC-12R fits a wide range of small commercial cooling jobs where central HVAC isn't enough.

Frequently Asked Questions
What outlet does the HSC-12R plug into?
The HSC-12R uses a standard 115V NEMA 5-15 plug with a 15-amp fuse — the same outlet you'd find in any office, kitchen, or commercial space. No special wiring or electrical upgrades required.
How much area will the HSC-12R cool?
With 12,000 BTU directed through a 5" cold air nozzle, the HSC-12R is built for spot cooling — targeting people, equipment, or specific work zones rather than cooling an entire room. Effective coverage depends on ambient temperature, layout, and heat sources.
What refrigerant does the HSC-12R use?
It uses modern, low-GWP R-454B refrigerant, meeting current environmental standards. The "R" suffix in the model name indicates this updated refrigerant generation versus the older R-410A version.
How is condensate water handled?
The HSC-12R has a 4-gallon built-in condensate tank with automatic shut-off when full, plus a tank position detector. For continuous drainage in high-humidity settings, an optional condensate pump plugs directly into the unit's quick-connect port.
Can the warm air exhaust be ducted?
Yes. The HSC-12R has a 12" diameter top flange that supports an optional warm air duct kit (8 ft of ducting + 2'x2' ceiling flange) to route warm exhaust into a drop ceiling or to an exterior wall.
Does the HSC-12R include a heater?
No. The HSC-12R is a cooling-only spot cooler. If you need year-round cooling and heating from a single unit, see Airrex's AHSC heat pump series.
