Airrex HWC-19R Water-Cooled Portable Spot Cooler — 18,200 BTU, R-454B, No Venting Required
The Airrex HWC-19R is a 1.5-ton water-cooled portable spot cooler engineered for spaces where warm air venting isn't an option. Instead of discharging heat into the room or out a duct, the HWC-19R uses a closed-loop water cooling system to remove condenser heat — making it ideal for hospitals, kitchens, production facilities, and tightly enclosed office spaces. Delivers 18,200 BTU of directed cooling through two 5-inch front cold air nozzles, uses modern R-454B refrigerant, and runs on a standard 115V outlet (NEMA 5-15 plug). Built-in condensate pump and twist-and-lock water connections make setup straightforward. ETL listed.
Key Features
Engineered for dependable performance with the features that matter most.
Water-Cooled, No Venting Required
A closed-loop water cooling system (2.9 gal/min condenser water) removes heat without warm air discharge — ideal for enclosed spaces where ducting isn't practical.
18,200 BTU Directed Cooling
1.5-ton spot cooling output through dual 5" front cold air nozzles — concentrated cooling for hot work zones in tight spaces.
Dual 5" Cold Air Nozzles
Two front-mounted 5" diameter cold air nozzles let you split airflow between two work zones or aim both at a single hot spot for concentrated cooling.
Eco-Friendly R-454B Refrigerant
Modern low-GWP R-454B refrigerant (1.11 lb charge) — meets current environmental standards while delivering reliable cooling performance.
Plug-and-Play 115V Power
Standard 115V single-phase, NEMA 5-15 plug, 15-amp fuse — no special wiring needed. Just connect water lines and plug in.
Built-In Condensate Pump
Auto condensate pump is included as standard — continuous moisture removal without manual tank emptying.
Note: The HWC-19R is engineered to operate with a closed water loop system — it requires a constant supply of cooling water (approx 2.9 gal/min) through twist-and-lock water inlet/outlet connections. Particularly suited to environments where ambient temperatures exceed 50°C (122°F) or where outdoor exhaust ducting is impossible. Operating range 65-118°F.
Ideal Applications
Water-cooled spot cooling for spaces where air-cooled units can't work — hospitals, enclosed kitchens, production facilities, and tightly sealed offices.

Frequently Asked Questions
What does "water-cooled" mean for this spot cooler?
Instead of discharging warm air through an exhaust duct (like a traditional air-cooled spot cooler), the HWC-19R uses a closed water loop to absorb and remove condenser heat. The unit needs a constant water supply (~2.9 gal/min) connected to its twist-and-lock inlet/outlet — but it doesn't put any warm air back into the room.
When is a water-cooled unit better than an air-cooled spot cooler?
Water-cooled is the right choice when you can't vent warm air — tightly enclosed spaces, sealed clean rooms, hospitals, indoor kitchens without exterior wall access, or environments where ambient temperatures are extremely high (>122°F) and air-cooled exhaust would overwhelm the space.
How much water does the HWC-19R need?
Approximately 2.9 gallons per minute of condenser water through a closed-loop system. Twist-and-lock water inlet and outlet connections make hookup straightforward.
What refrigerant does the HWC-19R use?
Modern, low-GWP R-454B refrigerant with a 1.11 lb charge. The "R" suffix indicates this updated refrigerant generation versus the older HWC-19 (R-410A).
What outlet does the HWC-19R plug into?
Standard 115V NEMA 5-15 plug on a 15-amp circuit — the same outlet you'd find in any office or commercial space. Power cord is 14 AWG, 3-core, 10 ft long.
Is the condensate pump built in?
Yes. The HWC-19R includes a built-in auto condensate pump as standard — continuous moisture removal without manual tank emptying.
