What is a portable spot cooler?

A portable spot cooler is a self-contained air conditioner designed to provide targeted cooling to a specific area, workstation, or piece of equipment without permanent installation.

What size area can the Airrex HSC-24R cool?

The Airrex HSC-24R delivers approximately 24,000 BTU of cooling and is designed for spot cooling applications such as manufacturing stations, server rooms, medical spaces, and heat-producing equipment—not entire buildings.

Is the Airrex HSC-24R commercial-grade?

Yes. The HSC-24R is a commercial-grade portable spot cooler built for industrial, healthcare, warehouse, office, and data room environments.

Does the Airrex HSC-24R require venting?

Yes. The warm exhaust air must be ducted out of the cooled space, typically through a ceiling tile, window, or wall opening using flexible exhaust ducting.

Does the Airrex HSC-24R require fresh air?

In many applications, Airrex spot coolers perform best when supplied with fresh or conditioned air, especially in enclosed or high-heat environments.

What refrigerant does the Airrex HSC-24R use?

The unit uses R-454B refrigerant, a low-GWP replacement for R-410A that meets modern environmental standards.

Does the HSC-24R include dehumidification?

Yes. The unit includes a built-in dehumidification mode in addition to cooling.

Where is the Airrex HSC-24R commonly used?

Common applications include production areas, server rooms, warehouses, healthcare facilities, and supplemental or emergency cooling situations.

Common Applications for the Airrex HSC-24R

Warehouses and Manufacturing Facilities

Warehouses and manufacturing facilities often contain specific workstations, production areas, or equipment that require additional cooling.

The Airrex HSC-24R can provide targeted cooling for machine operators, assembly lines, industrial equipment, packing stations, and other localized areas.

Its 24,000 BTU/hr cooling capacity offers more cooling power than smaller portable spot coolers, while the wheeled design allows the unit to be repositioned as operating requirements change.

Rather than cooling an entire warehouse, the HSC-24R can help address individual areas with elevated temperatures.

Server Rooms and IT Equipment Cooling

Server rooms, networking closets, and other IT environments generate substantial heat from continuously operating electronic equipment.

The HSC-24R can provide temporary or supplemental cooling during HVAC maintenance, equipment upgrades, or unexpected cooling failures.

Its 2-ton capacity makes it an option for server rooms requiring more cooling than a smaller 1-ton or 1.5-ton spot cooler can provide.

Proper heat-load calculations, airflow distribution, and condenser exhaust management are essential when using portable cooling in IT environments.

Learn more in our Best Portable Spot Coolers for Server Rooms in 2026 guide.

Commercial and Healthcare Facilities

The Airrex HSC-24R can provide supplemental cooling for commercial offices, healthcare support areas, retail facilities, and temporary workspaces.

Its portable design allows cooling equipment to be positioned where needed without requiring a permanent air conditioning installation.

For healthcare environments, equipment placement and operation should be evaluated against the facility’s requirements.

Emergency and Temporary Air Conditioning

Unexpected HVAC failures can interrupt business operations and expose temperature-sensitive equipment to excessive heat.

The Airrex HSC-24R provides a portable cooling option for temporary and emergency applications when properly sized and installed.

It can also be used during planned HVAC maintenance, equipment replacement, building renovations, and other projects requiring temporary cooling.

Installation and Electrical Requirements

The Airrex HSC-24R operates on 220V / 60Hz single-phase power and uses a NEMA 6-20 electrical plug.

Unlike smaller 115V Airrex spot coolers, the HSC-24R requires a compatible higher-voltage electrical connection. The unit cannot be plugged into a standard 115V household outlet.

Before ordering, customers should verify that their facility has the proper voltage, receptacle, and electrical circuit for the unit.

Warm Air Exhaust

Like other air-cooled portable air conditioners, the HSC-24R removes heat from the conditioned area and discharges it through the condenser exhaust.

Warm exhaust air must be routed away from the cooled area to prevent heat buildup and reduced cooling effectiveness.

The optional Airrex 12-inch ceiling tile kit allows warm condenser exhaust to be routed through a compatible ceiling installation when an appropriate exhaust path is available.

Condensate Management

The HSC-24R removes moisture from the air during cooling and dehumidification operation.

For applications requiring automatic condensate removal, an optional 220V condensate pump is available.

Adequate ventilation, proper electrical connections, and appropriate condensate management are important for reliable operation.

Optional Accessories for the Airrex HSC-24R

The Airrex HSC-24R is compatible with optional accessories that simplify installation, exhaust management, and condensate removal.

Airrex 12-Inch Ceiling Tile Kit

The Airrex 12-inch ceiling tile kit provides a convenient way to route warm condenser exhaust through a suspended ceiling installation where a suitable discharge path is available.

The kit includes:

24″ × 24″ pre-cut ceiling tile
12-inch diameter flexible exhaust duct
8-foot duct length

This accessory can help create a cleaner installation by keeping exhaust ducting organized in commercial offices, server rooms, and other facilities with suspended ceilings.

Airrex 220V Condensate Pump

The Airrex 220V condensate pump provides automatic condensate removal for compatible portable air conditioners, including the HSC-24R.

This accessory helps reduce the need for manual condensate removal and is particularly useful for applications requiring extended cooling operation.

It can be used when condensation needs to be pumped to an approved drainage location.

View Airrex 220V Condensate Pump

Both accessories are available separately through Climate Control Solutions and can be purchased alongside your HSC-24R.

Why Choose the Airrex HSC-24R?

The Airrex HSC-24R combines commercial-grade construction, 24,000 BTU/hr of cooling capacity, and convenient portability.

Its 2-ton capacity and 650 CFM airflow make it a strong option for applications requiring more cooling than smaller 115V spot coolers can provide.

The unit’s washable filters, built-in dehumidification, and compatible accessories offer additional flexibility for commercial and industrial installations.

  The spot coolers provided Climage Control Solutions saved the day at my office when our central ac went out in the entire building. The portable ac units kept us all very comfortable for several weeks while we waited for ours to be repaired. It only took 2 units to cool quite a large space. Thanks you CCS!!! We appreciate you!
