This is a large-capacity, single-speed portable evaporative cooler built for warehouses, production floors, loading docks, and other big open spaces that need spot or area cooling without ductwork.
Manufactured by Polar Cool, this 48" system is built around a galvanized steel frame with a black powder coat finish, designed to hold up under continuous industrial use. It fits facilities where traditional air conditioning is impractical or too costly to install across large open areas. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
System Components
- Single-speed fan drive delivering 17,500 CFM output
- Evaporative cooling media with coated pad edges for extended service life
- Galvanized steel housing with black powder coat finish
- Heavy-duty wheel base for repositioning across a facility
Installation Requirements & Accessories
- Requires a standard 120VAC single-phase circuit; draws 18A at 60 Hz
- Includes a 20-foot power cord; cord is Non-GFCI
- Requires adequate cross-ventilation (open doors, windows, or exhaust fans) to perform at rated capacity
- Not recommended for enclosed spaces without fresh air exchange
- Not effective in climates with high relative humidity - evaporative cooling performance drops as ambient humidity rises
- Water hose and continuous water-line hardware are not included
- Direct continuous water-line connection capability is not confirmed in available specifications [NEEDS VERIFICATION]
Pro-Installer Tip
Evaporative cooling only works when moving air can carry humidity out of the space - without cross-ventilation, this unit will raise humidity indoors instead of cooling it. Position the unit near an open bay door, loading dock, or exhaust fan path so the moisture-laden air has somewhere to go; this prevents condensation buildup on floors, equipment, and overhead structure. On the water side, this unit consumes roughly 17 gallons per hour, so plan your water supply and drainage accordingly, and inspect the cooling pads on a routine schedule since mineral buildup on pad media reduces evaporation efficiency over time. As a professional standard, evaporative cooling performs best in relative humidity below 60% - in more humid climates, expect reduced temperature drop regardless of airflow.
Key Benefits
- 17,500 CFM airflow rated for coverage up to 4,000 square feet
- Single-speed operation with straightforward controls - no complex settings to manage
- Heavy-duty wheels for repositioning across a warehouse or production floor
- Standard 120V power - no specialized electrical infrastructure required for installation
- Coated pad edges reduce media replacement frequency versus uncoated pads
- Runs without refrigerants, using water evaporation instead of a compressor cycle

FAQ
Does this unit require a continuous water connection?
The source specifications do not confirm whether this unit supports a continuous fill float valve or hose connection. [NEEDS VERIFICATION]
How large of a space will this evaporative cooler effectively cool?
This unit is rated for coverage up to 4,000 square feet, driven by a 17,500 CFM airflow rating.
Can this be used indoors without open windows?
No. Evaporative cooling depends on fresh air exchange. The manufacturer specifies adequate ventilation is required - open doors, windows, or exhaust fans - for the unit to perform as rated.
What kind of power outlet is required?
This unit runs on 120VAC single-phase power, drawing 18A at 60 Hz, and ships with a 20-foot Non-GFCI power cord.
