Airrex HWC-19R Portable Water-cooled Ac 18200 Btu/h 115V

Product Description

The AIRREX HWC-19R is a portable water-cooled air conditioner rated at 18,200 BTU/h, designed for spot cooling in industrial, commercial, and server room environments. Instead of exhausting heat through a duct to the outside, it uses a continuous supply of water to reject condenser heat, making it effective in enclosed spaces where vent ducting is not practical. The unit operates on a single-phase 115-volt, 60 Hz circuit and uses R-454B refrigerant. A centrifugal fan delivers conditioned air at two speed settings, with dual 5-inch discharge ducts for directed airflow. Licensed HVAC technicians and facilities maintenance crews are the primary installers and service personnel for this class of equipment.

The HWC-19R is suited for industrial facilities, data centers, server rooms, offices, and commercial kitchens where ambient heat loads are high and conventional split or window units are not feasible. Its portable, self-contained design allows relocation between work areas without permanent installation. The unit is sized for spot cooling of a targeted zone rather than whole-building conditioning, making it a practical choice for temporary or supplemental cooling applications in both rental fleets and permanent facility deployments.

Key Features

• 18,200 BTU/h cooling capacity using water-cooled condenser — no hot-air exhaust duct required
• R-454B refrigerant with lower global warming potential compared to legacy refrigerants
• Single-phase 115V/60 Hz operation with 14 AWG 3-core power cord, 10 feet in length
• Dual 5-inch discharge duct ports with centrifugal fan at high and low speed settings
• Aluminum air filter for reusable, cleanable filtration
• Portable, self-contained cabinet for repositioning without permanent installation

Compatibility

Designed as a self-contained portable water-cooled spot cooler for industrial and commercial environments requiring supplemental or temporary cooling where a condenser water supply is available.

Installation Notes

Installation and service should be performed by a licensed HVAC technician familiar with portable water-cooled equipment and applicable local mechanical codes. Before servicing internal components, disconnect the unit from its power source and shut off the condenser water supply lines. Confirm that supply water temperature and flow rate meet the requirements specified in the manufacturer user manual before startup. Do not operate the unit without verifying that drain lines are properly routed and that the water circuit is free of air locks.
