47,000 BTU Heating Performance for Commercial & Industrial Spaces

The Airrex AHSC-42 provides 47,000 BTU/h (13.8 kW) of heating capacity to help maintain comfortable temperatures in suitable commercial and industrial environments. Its specified heating operating range is approximately 50°F to 81°F, subject to the manufacturer's stated ambient temperature and humidity conditions. Reversible heat pump operation transfers heat into the conditioned space, providing substantial supplemental heating capacity for temporary work areas, industrial facilities, and other applications requiring flexible temperature control. Actual heating performance depends on ambient conditions, installation configuration, and the thermal load of the conditioned space.

42,000 BTU Cooling Performance for Large Commercial Areas

The Airrex AHSC-42 provides 42,000 BTU/h (12.3 kW) of cooling capacity, equivalent to approximately 3.5 tons, for high-capacity supplemental cooling. Its specified cooling operating range is approximately 65°F to 113°F under the manufacturer's stated ambient conditions. The unit is rated for spaces up to approximately 1,400 square feet under suitable conditions, although actual coverage varies with insulation, ceiling height, equipment heat loads, outdoor temperatures, and ventilation requirements. Duct-connected air distribution supports delivery of conditioned air to the intended work area while allowing flexible equipment placement.

Reversible Heat Pump Technology with Integrated Dehumidification

The Airrex AHSC-42 uses reversible heat pump technology to provide both heating and cooling from a single portable system. The refrigeration cycle operates in cooling mode to remove heat from the conditioned space and reverses in heating mode to deliver warm air. The system also incorporates a dedicated dehumidification mode to help remove excess moisture. The AHSC-42 specification identifies R-410A refrigerant with a listed refrigerant charge of approximately 6.62 lb. This integrated approach provides year-round climate control without requiring separate portable heating and cooling equipment.

Ducted Airflow & Distribution for Targeted Conditioning

The Airrex AHSC-42 features separate duct connections for conditioned-air delivery and return-air circulation. The system incorporates a nominal 12-inch supply duct connection and a 16-inch return duct connection, along with a top condenser exhaust outlet specified at approximately 26 inches in the product literature. An optional reducer may be used where compatible with the installation. The ducted configuration allows conditioned air to be routed toward the target area and supports flexible placement of the equipment. Duct lengths, routing, clearances, and any required fresh-air supply must follow the manufacturer's installation requirements to maintain appropriate airflow and operating performance.

Portable Design for Flexible Installation & Deployment

The Airrex AHSC-42 features a heavy-duty cabinet designed for portable commercial and industrial applications. Published product specifications list approximate dimensions of 29.1 inches wide by 57.1 inches deep by 50.7 inches high for the AHSC-42 220V single-phase configuration, with a listed weight of approximately 450 lb. Some product literature lists a slightly different cabinet height and weight depending on the documentation or configuration; verify the applicable model submittal before finalizing installation clearances and handling requirements. Swivel casters with locking capability and integrated handles support positioning on suitable surfaces. Duct connections allow the unit to be arranged for indoor or outdoor applications according to the manufacturer's requirements. The system requires a suitable 220V, 60Hz, single-phase electrical supply.

Integrated Dehumidification for Moisture Control

The Airrex AHSC-42 provides integrated dehumidification to help manage excess moisture in commercial and industrial environments. Published specifications identify maximum moisture removal of up to 59 gallons per day and a nominal AHAM-rated removal capacity of approximately 40.6 gallons per day. Maximum moisture removal is based on specified test conditions and should not be interpreted as the expected daily output in every application. The specified dehumidification operating range is approximately 59°F to 113°F under the applicable ambient conditions. An optional external condensate pump is available for compatible installations requiring continuous condensate removal. Drainage arrangements must be configured according to the manufacturer's instructions.

Digital Controls, Comfort Settings & Electrical Connection

The Airrex AHSC-42 incorporates a digital controller with temperature adjustment, timer functions, and remote-control capability as identified in the product literature. The controller also supports system monitoring and self-diagnostic functions on applicable configurations. The AHSC-42 220V single-phase model operates on a 220V, 60Hz, single-phase electrical supply. Published electrical specifications list approximately 4.5 kW of power consumption and 21 amps of current consumption in both cooling and heating modes. The manufacturer specifies a 30-amp circuit breaker for this configuration. The unit should be connected using the approved electrical connection and circuit protection specified for the exact model. Electrical installation must comply with applicable codes and be completed by qualified personnel. Verify the current model nameplate and installation manual before selecting conductors, overcurrent protection, or disconnect equipment.

Commercial & Industrial Applications for Supplemental HVAC

The Airrex AHSC-42 is designed for commercial and industrial environments requiring high-capacity portable heating, cooling, and dehumidification. Potential applications include warehouses, manufacturing facilities, workshops, maintenance areas, equipment rooms, temporary workspaces, industrial production areas, and event or temporary structures. Its 42,000 BTU cooling capacity, 47,000 BTU heating capacity, and duct-connected configuration make it suitable for applications where permanent HVAC installation is impractical or where temporary conditioning is required. Proper application sizing, electrical capacity, duct routing, ventilation, ambient operating conditions, and condensate management should be evaluated before deployment.

Mobility & Flexible Deployment Between Work Areas

The Airrex AHSC-42 incorporates heavy-duty swivel casters with locking capability and integrated handles to facilitate positioning and movement on suitable surfaces. Its portable construction supports deployment in different locations as work requirements change, while the duct connections allow conditioned air to be directed toward the intended space. Because the unit weighs several hundred pounds, relocation requires appropriate handling equipment and safe movement procedures. Secure the casters during operation and follow the manufacturer's instructions for shutdown, duct disconnection, transportation, and repositioning.

Service & Maintenance for Reliable Operation

The Airrex AHSC-42 includes removable, washable air filters to simplify routine cleaning and help maintain airflow. Regular filter inspection and cleaning are important for maintaining system performance. The compressor is equipped with thermostatic protection and high- and low-pressure warnings to support equipment protection. The digital control system includes diagnostic functionality as identified in the product literature. Condensate drainage components should be inspected regularly, and any optional condensate pump should be maintained according to its manufacturer's instructions. Refrigeration-system servicing, electrical repairs, and internal component maintenance should be performed by qualified service personnel in accordance with the applicable installation and operating manual.

Warranty

The Airrex AHSC-42 is listed with a one-year warranty and a three-year compressor warranty in the manufacturer's product literature. Warranty coverage, exclusions, service requirements, and other applicable conditions are subject to the manufacturer's written warranty documentation. Confirm the warranty terms applicable to the purchased model and installation before operation.
