18,200 BTU Cooling Performance and Water-Cooled Refrigeration

The Airrex HWC-19R provides a rated cooling capacity of 18,200 BTU/h under the manufacturer's specified rating conditions of 95°F dry-bulb temperature and 40% relative humidity. Its water-cooled refrigeration system uses R-454B refrigerant and a regulated condenser-water supply to remove heat without relying on a conventional outdoor-air exhaust duct. This design is particularly useful for commercial and industrial environments where routing hot exhaust air outdoors is difficult or impractical. The specified operating temperature range for cooling is approximately 65°F to 118°F, subject to the manufacturer's operating conditions. Actual cooling performance depends on ambient conditions, internal heat loads, occupancy, and the availability of an adequate condenser-water supply. The unit also provides dehumidification performance rated at approximately 13 gallons per day maximum and 9 gallons per day nominal under the manufacturer's specified test conditions.

Water-Cooled Operation and Targeted Temperature Control

The Airrex HWC-19R is designed to deliver targeted cooling directly to employees, machinery, workstations, and other areas requiring supplemental temperature control. Unlike conventional air-cooled portable air conditioners, the HWC-19R uses condenser water to remove refrigeration-system heat, avoiding the need for a conventional hot-air exhaust duct. Its water-regulating valve controls the condenser-water supply, while designated water-inlet and water-outlet connections support integration with a suitable water system. The manufacturer specifies a condenser-water flow rate of approximately 2.9 gallons per minute. The unit is intended for use with an appropriate closed-loop water system, where compatible with the installation. Two front-mounted 5-inch cold-air nozzles feature twist-and-lock directional adjustment, allowing conditioned air to be aimed toward specific cooling zones without requiring a permanent HVAC installation.

Airflow and Distribution

The Airrex HWC-19R uses a centrifugal fan system to deliver conditioned air through two 5-inch cold-air discharge connections. The rated evaporator airflow is approximately 520 CFM on high speed and 450 CFM on low speed. The two directional nozzles allow users to distribute cooled air toward individual workstations, equipment, or designated areas. High- and low-fan-speed settings provide flexibility for different airflow requirements. The water-cooled condenser design eliminates the need for conventional hot-air exhaust ducting, helping simplify placement in facilities where duct routing is restricted. Maintaining unobstructed air inlets and outlets and providing the specified condenser-water flow are important for reliable cooling performance.

Portable Design and Flexible Installation

The self-contained portable design allows the Airrex HWC-19R to be positioned where supplemental cooling is needed without requiring a permanent HVAC installation. The cabinet measures approximately 18 inches wide, 23 inches deep, and 43 inches high, with a net weight of approximately 163 pounds. Four 4-inch swivel casters support movement between suitable work areas, while two locking casters help secure the unit during operation. The HWC-19R requires a 115V, single-phase, 60 Hz electrical supply and uses a NEMA 5-15 plug configuration. Installation requires access to a suitable condenser-water supply and return connections, along with the appropriate electrical connection and adequate clearance for air circulation and maintenance. The water-cooled configuration avoids the need for a conventional hot-air exhaust duct, making the unit suitable for locations where outdoor exhaust routing is impractical. Water connections and flow requirements must be verified before operation.

Condensate Management

The Airrex HWC-19R incorporates an automatic condensate pump to remove moisture collected during cooling and dehumidification operation. The manufacturer's specifications identify the automatic condensate pump as included equipment. The unit also incorporates condensate-related safety functions, including automatic full-tank shutoff and tank-position detection, as listed in the manufacturer's technical documentation. These features help manage condensate and protect against operation under unsuitable collection conditions. The condensate discharge must be routed to an appropriate drainage point in accordance with the manufacturer's instructions. The condensate pump handles moisture removed from the conditioned air and is separate from the condenser-water circuit used for heat rejection.

Controls, Comfort, and Electrical Connection

The Airrex HWC-19R features digital operating controls with thermostat-based temperature adjustment, high- and low-fan-speed selection, and programmable timer settings. The documented temperature-setting range is approximately 64°F to 86°F. Safety features include high- and low-pressure switches, a compressor thermostat protector, fan motor protection, a three-minute compressor delay timer, automatic full-tank shutoff, and tank-position detection. The unit requires a 115V, single-phase, 60 Hz power supply, with rated cooling current consumption of approximately 11.9 amps and cooling power consumption of approximately 1.24 kW. The manufacturer's specification lists a NEMA 5-15 plug, 14 AWG three-core power cord, and an approximately 10-foot cord length. A compatible grounded electrical supply must be provided in accordance with the manufacturer's requirements and applicable electrical codes. The condenser-water supply must also meet the specified flow and connection requirements before operation.

Commercial and Industrial Applications

The Airrex HWC-19R is designed for commercial and industrial environments requiring targeted cooling where conventional air-cooled equipment or permanent HVAC installations may be impractical. Suitable applications identified in the manufacturer's product literature include hospitals, kitchens, production facilities, and office complexes. The water-cooled heat-rejection system is particularly useful in locations where routing hot exhaust air outdoors is difficult or where conventional exhaust ducting is undesirable. Its 18,200 BTU/h cooling capacity and two adjustable cold-air nozzles support localized cooling for workstations, equipment, and designated occupied areas. The portable configuration allows the unit to be repositioned as operational requirements change, provided that suitable water connections, drainage, electrical service, and airflow clearance are available.

Mobility and Deployment

The Airrex HWC-19R is equipped with four 4-inch swivel casters, including two locking casters, to support movement and positioning on suitable level surfaces. Its self-contained construction and directional cold-air nozzles allow the unit to be deployed where supplemental cooling is required. Once positioned, the locking casters help secure the cabinet during operation. The water-cooled configuration eliminates the need for conventional hot-air exhaust ducting, but the unit must remain connected to an appropriate condenser-water supply and discharge arrangement while operating. Before deployment, verify floor load capacity, water-flow availability, drainage arrangements, electrical compatibility, and sufficient clearance for maintenance.

Service and Maintenance

The Airrex HWC-19R features removable aluminum and stainless-steel mesh air filters to simplify routine maintenance. Filters should be inspected and cleaned regularly according to the operating environment and dust loading. The air inlets and cold-air discharge nozzles should remain unobstructed to maintain appropriate airflow. The condenser-water circuit, water-regulating valve, inlet and outlet connections, and automatic condensate pump should be inspected and maintained according to the manufacturer's instructions. Built-in compressor protection, pressure switches, fan motor protection, a compressor delay timer, automatic full-tank shutoff, and tank-position detection provide additional operating safeguards. Disconnect the electrical supply and follow the manufacturer's maintenance procedures before cleaning or servicing the equipment.

Warranty

The Airrex HWC-19R includes a manufacturer's warranty consisting of one year of general warranty coverage and three years of compressor coverage, as stated in the manufacturer's product literature. Warranty eligibility, covered components, labor coverage, and applicable conditions are subject to the manufacturer's current written warranty terms. Proof of purchase and compliance with applicable installation, operating, and maintenance requirements may be required for warranty service. Confirm the precise warranty terms with Airrex USA or an authorized distributor before purchase.
