Airrex & Flagro HSC-24R Spot Cooler 23500 BTU 2 Ton 65F to 118F R-454B Refrigerant 2 Nozzles Removable Filter ETL Listed
Airrex HSC-24R Spot Cooler — 23,500 BTU 2-Ton Portable Air Conditioner
The Airrex HSC-24R is a commercial-grade 2-ton portable spot cooler that delivers 23,500 BTU/h of directed cooling exactly where you need it — no ductwork, no permanent installation, no downtime. Engineered with next-generation low-GWP R-454B refrigerant and a thermostatically protected compressor, this 220-volt single-phase unit is built for industrial floors, server rooms, restaurant kitchens, workshops, and event venues that demand reliable, targeted climate control. Rolling easily on four swivel casters with two locking, the HSC-24R moves with your operation and goes to work in minutes.
Key Features of the HSC-24R
Every detail of the Airrex HSC-24R is built around one goal: pushing dependable, cold air into the workspace while keeping maintenance, environmental impact, and downtime low.
23,500 BTU Directed Cooling
Two 5" front cold-air discharge nozzles aim concentrated cooling at workstations, equipment, or crowds — 2 tons of capacity placed precisely where heat builds up.
Eco-Friendly R-454B Refrigerant
The HSC-24R runs on next-generation, low-GWP R-454B — a modern replacement for R-410A that meets current environmental standards, including California compliance.
Thermostatically Protected Compressor
A built-in compressor thermostat plus high- and low-pressure switches and a 3-minute delay timer guard against overheating and short-cycling for long, reliable service life.
Mobile, Lockable Caster Design
Four swivel casters — two of them locking — let the HSC-24R roll between zones and then stay firmly planted once positioned, so cooling stays exactly where you set it.
Removable, Washable Air Filters
Aluminum + stainless-steel mesh filters slide out for quick cleaning, protecting internal components and keeping airflow strong with simple, tool-free maintenance.
Cooling, Fan & Dehumidification Modes
Digital controls with a programmable timer and auto-restart switch between cooling, fan, and a built-in dehumidification mode for moisture control in humid environments.
Installation note: The HSC-24R is a self-contained spot cooler — warm air is exhausted through the flared 12" top discharge. For best performance in enclosed or confined areas, provide a fresh-air supply and route the warm air outside the cooled zone. An optional warm-air duct kit (ducting plus a 2' × 2' ceiling flange) and an optional condensate pump are available separately.
Ideal Applications
With 2 tons of portable cooling and a rugged build, the Airrex HSC-24R fits demanding commercial and industrial settings where permanent HVAC is impractical or insufficient.

Frequently Asked Questions
What refrigerant does the Airrex HSC-24R use?
The HSC-24R uses R-454B, a next-generation, low-GWP refrigerant that replaces R-410A. It delivers efficient cooling while meeting modern environmental standards, including California compliance requirements.
What size area can the HSC-24R cool?
With 23,500 BTU/h (2 tons) of cooling capacity, the HSC-24R is built for spot cooling — directing concentrated cold air at workstations, equipment, server rooms, or crowds rather than conditioning an entire building. Actual coverage depends on heat load, insulation, and ambient conditions.
What power supply does the HSC-24R require?
The unit runs on 220V single-phase, 60 Hz power, draws 12.8 A while cooling, and uses a NEMA 6-20 plug with a 20 A fuse. It ships with a 10-ft, 12 AWG three-core power cord.
Does the HSC-24R need an exhaust or fresh-air setup?
Yes. As a self-contained spot cooler, it exhausts warm air through the flared 12" top discharge. In enclosed or confined areas, provide a fresh-air supply and route warm air out of the cooled zone. An optional warm-air duct kit with a 2' × 2' ceiling flange is available for ceiling exhaust.
How does the HSC-24R handle condensate?
The unit includes a 5-gallon condensate tank with an automatic full-tank shut-off to prevent overflow. For continuous, uninterrupted operation — or where condensate must be moved vertically or over distance — an optional plug-in condensate pump is available.
Is the HSC-24R certified, and what warranty is included?
The Airrex HSC-24R is ETL listed for safety and quality. It is covered by a 1-year warranty on the complete unit and a 3-year warranty on the compressor.
