Airrex HSC-24R Portable Spot Cooler 23500 Btu/h 220V R-454B

Product Description

The AIRREX HSC-24R is a self-contained, air-cooled portable spot cooler rated at 23,500 BTU/h (2 ton) of cooling capacity. It operates on 220 volts, single-phase, 60 Hz power and uses R-454B refrigerant, a low-GWP, A2L-classified refrigerant compliant for use in all 50 states. The unit handles operating temperatures from 59 degrees F to 118 degrees F, making it appropriate for demanding commercial and industrial environments. Two 5-inch front discharge nozzles deliver conditioned air directly to a target zone, and a 12-inch top exhaust outlet rejects warm air away from the conditioned space. EPA Section 608-certified HVAC technicians and facilities maintenance professionals are the primary service personnel for this class of equipment.

The HSC-24R is built for commercial and industrial spot-cooling applications where a ducted system is not available or practical. Typical deployments include server rooms, manufacturing floors, warehouse staging areas, temporary work enclosures, and event spaces requiring localized cooling. The unit covers areas up to approximately 800 to 1,000 square feet depending on heat load and ceiling height. Airflow is rated at 650 CFM on the high setting and 580 CFM on the low setting, giving technicians flexibility to match output to the application without overcooling adjacent areas. The self-contained, wheeled design requires no permanent installation or ductwork tie-in.

Key Features

• 23,500 BTU/h (2 ton) cooling capacity suited for high-heat commercial and industrial environments
• R-454B refrigerant — low-GWP, A2L-classified, compliant in all 50 states as of 2025
• Dual 5-inch front discharge nozzles for directed spot cooling to targeted zones
• 12-inch top warm-air exhaust outlet for heat rejection away from the conditioned space
• Two-speed airflow: 650 CFM high and 580 CFM low for adjustable output
• 220V single-phase operation compatible with standard commercial power drops
• Self-contained portable design requires no permanent installation or ductwork tie-in

Compatibility

Designed as an OEM-specified portable spot cooler for commercial and industrial temporary or supplemental cooling applications requiring a self-contained 220V single-phase unit with R-454B refrigerant.

Installation Notes

Installation and service must be performed by an EPA Section 608-certified HVAC technician, as the HSC-24R contains R-454B, an A2L mildly flammable refrigerant requiring appropriate handling procedures. Before servicing or relocating the unit, disconnect power at the circuit breaker and allow the system to depressurize per manufacturer guidance. Keep the top warm-air exhaust outlet unobstructed and directed to an unconditioned space or outdoors to maintain rated cooling performance. Confirm that the supply circuit is rated for the unit amperage draw and that all electrical connections meet applicable NEC requirements.
