The Uninex KoolZone SAC3000 Spot Cooler is a 10,236 BTU industrial spot cooler with twin flexible ducts, automatic oscillation, ETL certification and R-32 refrigerant that runs on an ordinary 110V, 10A supply. For more models, see our Portable Spot Coolers page.
Our Verdict
The SAC3000 is the most practical KoolZone for most businesses. It draws only 10 amps, so it runs from a normal outlet, and its twin oscillating ducts cover more ground than a single nozzle.
It has less capacity than a one ton industrial unit, and Uninex does not list its weight or noise level.

Design
Twin flexible ducts adjust to the angle you need, and automatic oscillation sweeps the cold air across a wider area. A front intake design lets the unit sit close to a wall, which helps in tight aisles.
At 17.7 by 18.5 by 37.4 inches, it takes less floor space than most industrial units, and Uninex suggests placing it where you would otherwise run a fan.
Controls
Operation is straightforward: switch it on, set the ducts and let the oscillation spread the air.
It is ETL certified and uses R-32 refrigerant, and Uninex lists uses from factories and golf ranges to car repair shops and stores.
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 the Uninex KoolZone SAC4500, the SAC3000 cools less but plugs into a standard 10 amp outlet instead of needing a 20 amp circuit.
Against one ton industrial units, the SAC3000 is smaller and certified, while those units cool more and carry larger tanks.
