Why Cool Boss
Cool Boss portable evaporative air coolers combine water, evaporative media and high-volume airflow to bring cooling where traditional air conditioning may not make sense.
Cooling designed for spaces that are hard to cool.
A Better Fit for Hot Workspaces
Garages, service bays, warehouses and other large workspaces don't always behave like conventional climate-controlled buildings.
Doors open. Vehicles move. Equipment generates heat. Work areas change throughout the day. Permanently cooling every square foot isn't always the most practical approach.
Cool Boss takes a different approach. Warm air is drawn through water-saturated evaporative media, and a high-volume fan distributes the cooled air into the surrounding workspace.
The result is a portable cooling solution designed around airflow, straightforward operation and the ability to bring cooling closer to the work.
