100,000 BTU Heating Performance for Commercial & Industrial Spaces

The Airrex AHSC-140R 220/3 provides 100,000 BTU/h (29.3 kW) of heating capacity for supplemental temperature control in commercial and industrial environments. Unlike reversible heat pump models, the AHSC-140R uses integrated electric resistance heating to provide warm air. Its specified heating operating range extends from approximately 1°F to 81°F, subject to the manufacturer's stated ambient temperature and humidity conditions. This heating capability supports temporary work areas, industrial facilities, warehouses, and other applications requiring high-capacity heating. Actual performance depends on ambient conditions, installation configuration, and the thermal load of the conditioned space.

145,000 BTU Cooling Performance for Large Industrial Areas

The Airrex AHSC-140R 220/3 provides 145,000 BTU/h (42.5 kW) of cooling capacity, equivalent to approximately 12.1 tons. Its specified cooling operating range extends from 65°F to 113°F under the manufacturer's stated ambient conditions. The system is designed for high-capacity supplemental cooling in large commercial and industrial spaces. Its air-cooled refrigeration system removes heat from the conditioned environment and rejects it through the designated exhaust arrangement. Actual cooling performance depends on ambient temperature, insulation, equipment heat loads, ventilation, duct configuration, and installation conditions.

Air-Cooled Refrigeration Technology with Electric Resistance Heating

The Airrex AHSC-140R 220/3 uses an air-cooled refrigeration system for cooling and integrated electric resistance heating for supplemental warmth. This configuration differs from reversible heat pump models because heating is provided by electric heating elements rather than reversing the refrigeration cycle. The system uses R-410A refrigerant with a specified charge of approximately 11 lb. Its separate cooling and heating functions allow the equipment to provide seasonal temperature control from one portable cabinet. Refrigeration servicing must be performed by qualified personnel using procedures and equipment appropriate for the specified refrigerant.

High-Volume Airflow & Ducted Distribution

The Airrex AHSC-140R 220/3 incorporates duct connections for supply air, return air, and condenser exhaust. Its indoor centrifugal fan provides approximately 4,800 CFM of airflow, with a maximum external static pressure of 1.2 inches of water column and a maximum equivalent indoor duct length of 100 feet. The condenser airflow is approximately 7,000 CFM, with a maximum equivalent exhaust duct length of 120 feet. A nominal 16-inch supply duct and 16-inch return duct support conditioned-air delivery and return-air circulation, while a 20-inch exhaust connection supports heat rejection. Correct duct sizing, routing, and clearances are essential for maintaining airflow and operating performance.

Portable Heavy-Duty Design for Flexible Installation

The Airrex AHSC-140R 220/3 features a heavy-duty cabinet designed for demanding commercial and industrial applications. Published specifications list approximate dimensions of 35 inches wide by 77 inches deep by 69 inches high, with a net weight of approximately 1,424 lb. Four locking swivel casters support positioning on suitable surfaces. The ducted configuration allows the unit to be arranged for different installation requirements when the manufacturer’s ventilation, exhaust, clearance, and ducting requirements are met. Due to its substantial weight, relocation requires suitable material-handling equipment, a properly rated floor, and safe movement procedures. Confirm access dimensions and installation clearances before deployment.

Integrated Dehumidification for Moisture Control

The Airrex AHSC-140R 220/3 includes a dedicated dehumidification mode to help manage excess moisture in commercial and industrial environments. Published specifications identify maximum moisture removal of up to 127 gallons per day and AHAM-rated moisture removal of approximately 87.5 gallons per day. Maximum moisture removal is based on specified test conditions and should not be interpreted as expected daily output in every application. The specified dehumidification operating range is approximately 59°F to 113°F. The unit includes a condensate drainage connection for managing collected moisture. Drainage arrangements must follow the manufacturer's installation and operating instructions.

Digital Controls, Operating Modes & Electrical Connection

The Airrex AHSC-140R 220/3 features a digital controller for selecting cooling, heating, fan, and dehumidification modes. The controls support temperature adjustment and an off-timer programmable from 0 to 24 hours, with room-temperature and operating-status indicators. The unit operates on a 220V AC, 60Hz, three-phase electrical supply. Published specifications list power consumption of approximately 19.1 kW during cooling and 29 kW during heating, with current consumption of approximately 50.2 amps during cooling and 77 amps during heating. The unit uses a power plug socket arrangement specified by the manufacturer and requires a properly rated three-phase electrical connection. The electrical circuit, conductors, disconnect equipment, and overcurrent protection must be selected according to the exact equipment nameplate and manufacturer's wiring diagram. Electrical installation must comply with applicable codes and be completed by qualified personnel.

Commercial & Industrial Applications for Supplemental HVAC

The Airrex AHSC-140R 220/3 is designed for large commercial and industrial environments requiring high-capacity cooling, electric heating, and dehumidification. Potential applications include warehouses, manufacturing facilities, industrial production areas, equipment rooms, maintenance facilities, temporary workspaces, and other locations requiring supplemental HVAC. Its 145,000 BTU/h cooling capacity, 100,000 BTU/h heating capacity, and high-volume ducted airflow support demanding applications where permanent HVAC installation is impractical or 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-140R 220/3 features four locking swivel casters to support positioning and movement on suitable surfaces. Its heavy-duty cabinet allows the equipment to be deployed in different work areas as cooling, heating, or dehumidification requirements change. Given its approximate 1,424 lb weight, relocation requires appropriate material-handling equipment and safe movement procedures. Lock 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-140R 220/3 incorporates pleated paper prefilters accessible through a service panel for routine inspection and replacement. Keeping filters clean helps maintain airflow and system performance. Built-in protection features include high- and low-pressure switches, a three-minute compressor delay timer, compressor thermostat protection, and fan motor protection. The digital controller provides operating-status and error indicators to assist with troubleshooting. Condensate drainage components should be inspected regularly. Refrigeration-system servicing, electric heater repairs, electrical maintenance, and internal component servicing must be performed by qualified personnel in accordance with the manufacturer's operating and service documentation.

Warranty

The Airrex AHSC-140R 220/3 is covered by the manufacturer's applicable written warranty. The warranty period, coverage, exclusions, service requirements, and proof-of-purchase conditions must be confirmed using the warranty documentation supplied with the purchased unit.
