12,000 BTU Cooling Performance and Refrigeration Technology

The Airrex HSC-12R provides 12,000 BTU/h (approximately 3,500 W) of cooling capacity to help maintain comfortable temperatures in commercial work areas, equipment rooms, workshops, and other locations requiring supplemental cooling. The air-cooled refrigeration system uses R-454B refrigerant and is designed for an approximate coverage area of up to 400 square feet under suitable conditions. Actual cooling coverage depends on ambient temperature, equipment heat generation, occupancy, insulation, and other environmental factors. The unit operates in cooling mode at ambient temperatures ranging from approximately 65°F to 113°F, providing a practical solution for demanding indoor and industrial environments.

Spot Cooling and Targeted Temperature Control

The Airrex HSC-12R is designed to deliver targeted cooling directly to employees, equipment, workstations, and other areas where additional temperature control is needed. Its front-mounted 5-inch cold-air discharge nozzle directs conditioned air toward the intended cooling zone, while selectable spot and room cooling settings provide flexibility for different applications. A separate dehumidification mode removes moisture without operating as a conventional cooling mode, supporting moisture management in appropriate environments. This portable spot cooler allows cooling to be directed where it is needed without requiring a permanent HVAC installation.

Airflow and Distribution

The Airrex HSC-12R uses a forced-air cooling system with a dedicated cold-air discharge and a separate warm-air exhaust. The 5-inch front cold-air nozzle directs conditioned air toward the target area, while the 10-inch top warm-air discharge supports exhaust-air removal. The unit includes high- and low-fan-speed settings to accommodate different airflow requirements. An optional warm-air exhaust duct can be used to route hot condenser air away from the installation area, helping support appropriate ventilation and cooling performance. Proper clearance around the unit and suitable exhaust-air management are important for reliable operation.

Portable Design and Flexible Installation

The self-contained portable design allows the Airrex HSC-12R to be positioned where supplemental cooling is needed without requiring a permanent HVAC installation. Four swivel casters, including two locking casters, support movement and positioning on suitable level surfaces. Measuring approximately 17 inches wide, 25 inches deep, and 42 inches high, the unit has a compact footprint for a commercial spot cooler. Its operating weight is approximately 129 pounds. The unit requires a 115V, single-phase, 60 Hz electrical supply and can connect to a compatible grounded outlet. An optional warm-air exhaust duct, supplied with an 8-foot duct and a 2-by-2-foot ceiling flange, can help direct condenser exhaust into an appropriate ventilation location. Installation should provide sufficient clearance for airflow and access to the condensate tank, filters, and electrical connection.

Condensate Management

The Airrex HSC-12R incorporates a condensate collection tank to collect moisture produced during cooling and dehumidification operation. The tank includes water-level sensing to help identify when condensate requires attention, and the unit provides an indicator for checking the tank or its position. An automatic full-tank shutoff helps prevent continued operation when the tank reaches its limit. For installations requiring an alternative method of condensate removal, an optional condensate pump is available. The tank should be inspected and emptied as necessary to maintain reliable operation.

Controls, Comfort, and Electrical Connection

The Airrex HSC-12R features a digital controller for convenient operating adjustments. The controls provide power selection, cooling, fan, and dehumidification modes, high- and low-fan-speed selection, temperature adjustment, and an off timer. The digital display indicates operating information, including room temperature and selected temperature or timer settings. Compressor protection and high- and low-pressure warnings help identify abnormal operating conditions. The unit requires a 115V, single-phase, 60 Hz power supply, draws approximately 11.4 amps, and uses a compatible LCDI power cord with a NEMA 5-15P plug. A properly grounded, compatible 15-amp electrical circuit is recommended. Electrical requirements and applicable local codes should be verified before installation.

Commercial and Industrial Applications

The Airrex HSC-12R is designed for commercial and industrial applications requiring supplemental or localized cooling. Suitable applications include offices, server rooms, equipment rooms, repair shops, manufacturing work areas, workshops, retail spaces, and temporary work areas. Its 12,000 BTU/h cooling capacity, directional cold-air discharge, and spot and room cooling settings make it useful for targeting heat-generating equipment or occupied workstations without installing a permanent cooling system. The portable configuration also supports changing cooling requirements across suitable work areas. Proper ventilation and exhaust-air management must be provided according to the installation environment.

Mobility and Deployment

The Airrex HSC-12R is equipped with four swivel casters, including two locking casters, for convenient movement and positioning. Its compact cabinet and self-contained construction allow the unit to be relocated between compatible work areas as cooling requirements change. Once positioned, the locking casters help secure the unit during operation. For effective deployment, the installation area should provide adequate airflow clearance, access to an appropriate electrical outlet, and a suitable route for warm-air exhaust where ducting is used.

Service and Maintenance

The Airrex HSC-12R features removable, washable air filters to simplify routine maintenance and help maintain adequate airflow. Filters should be inspected and cleaned regularly, with frequency determined by the operating environment and dust loading. The condensate collection tank should also be checked and emptied as required. Maintaining appropriate clearance around the evaporator and condenser air inlets and outlets is important for proper performance. Compressor protection and high- and low-pressure warning functions provide additional operating safeguards. Before performing cleaning or maintenance, disconnect the power supply and follow the manufacturer's operating and maintenance instructions.

Warranty

The Airrex HSC-12R includes a standard one-year warranty covering parts and labor for manufacturer defects, along with a three-year warranty on the compressor, subject to the manufacturer's applicable warranty terms and conditions. Proof of purchase and compliance with the applicable installation, operating, and maintenance requirements may be required for warranty service. Customers should confirm coverage details with their authorized Airrex distributor before purchase.
