The HayWHNKN 18,700 BTU Industrial Spot Cooler is an industrial spot cooler that delivers 18,700 BTU on a 110V, 60Hz supply at 1800W, with 950 cubic meters per hour of cold airflow and two adjustable outlets. For more models, see our Portable Spot Coolers page.
Our Verdict
This HayWHNKN is the strongest spot cooler we found that still runs on 110V. It is a good fit for a warehouse aisle or a busy repair bay where a one ton unit falls behind.
It weighs 175 pounds, the 14L bucket needs emptying, and there is no noise figure. Plan a circuit that is not shared with big tools.

Design
A centrifugal fan moves 950 cubic meters per hour of cold air through two flexible outlets and an expandable duct you can adjust in length and direction. Hot air leaves at 2300 cubic meters per hour.
A 14L condensate bucket is hidden inside the cabinet, a protective net covers the fan, and ergonomic grooved handles plus universal casters help move it.
Controls
The integrated panel sets speed, air volume and outlet temperature, from 0 to 30°C.
An automatic diagnosis system stops the machine and shows a fault code when the tank is full or when it detects overcurrent, overheating or high pressure. HayWHNKN lists a current of 6.6A and a maximum of 7.4A.
Placement Tips
Put the cold air outlet within a few feet of the people or equipment you want to cool, and point the hot exhaust away from them. Indoors, run the exhaust to a drop ceiling, an open doorway or an exterior vent, otherwise the unit only moves heat around the room.
Leave open space around the intake so the unit can breathe, keep it on a level floor, and plug it straight into a grounded outlet on a circuit that is not shared with large tools. Outdoors, keep it out of standing water and under a roof or canopy unless the listing gives it a weather rating.
Running Costs and Care
Running cost depends on how many hours a day the compressor runs and on your electricity rate. Spot coolers draw far more power than a fan but far less than cooling a whole building, which is why they make sense for one work area or a short summer peak.
Clean or wash the air filter often, especially in dusty shops, and check the condenser coil for dirt and lint at the start of each season. Empty the condensate tank or check the drain line regularly, and before storing the unit, run it in fan mode to dry it out and drain all remaining water.
How It Compares
Against one ton industrial units from the same price tier, this model cools far more on the same 110V supply but is heavier and larger.
Against the Global Industrial 3 ton unit, the HayWHNKN cools less but avoids the need for a 230V outlet and costs much less.
