COOLBREEZE
Cooling That Doesn't Stand Still.
The Cool Boss COOLBREEZE Series combines direct evaporative cooling with automatic swing louvers that continuously redirect outgoing airflow.
That makes COOLBREEZE a practical option when you want moving air distributed across a broader work area instead of focused in one fixed direction.
Portable designs allow the cooler to move with changing workflows, while model-specific controls and features help you adjust operation for the application.
Coolbreeze Series
Why choose the Cool Boss COOLBREEZE Series for your cooling needs?
Because it delivers powerful, energy-efficient airflow that transforms hot, uncomfortable spaces into cool, productive environments. Using advanced evaporative cooling, COOLBREEZE drops air temperatures by up to 26°F—without the high costs of traditional A/C. It works by drawing warm air through water-saturated cooling media, creating a refreshing, eco-friendly breeze that’s clean, quiet, and effective. Built to thrive in warehouses, garages, patios, and workshops, each unit features rugged casters for mobility, intuitive digital controls for ease of use, and automatic swing louvres that evenly distribute cool air across a wider area—so no one gets left in the heat. Whether you're in a commercial, industrial, or open-air setting, the COOLBREEZE Series offers a smarter, portable solution. Just plug it in, fill it up, and let Cool Boss deliver serious comfort, wherever work takes you.

Designed to Move Air
A Wider Approach to Airflow.
Evaporative Cooling
Warm incoming air passes through wetted evaporative media before the fan moves the resulting cooler air into the space.
Portable Placement
Casters make it possible to reposition the cooler as work areas, people and airflow needs change.
Environment Matters.
Direct evaporative cooling generally performs best in hot, dry conditions with adequate ventilation. Ambient temperature, relative humidity, airflow, placement, water conditions and the individual COOLBREEZE model all affect real-world results.

Frequently Asked Questions
COOLBREEZE Questions?
Learn how swing louvers, evaporative cooling, ventilation and placement affect the way a COOLBREEZE operates.
What is the COOLBREEZE Series?
COOLBREEZE is a line of portable direct evaporative air coolers featuring automatic swing louvers designed to distribute outgoing airflow across a broader area.
What COOLBREEZE models are available?
The current COOLBREEZE category includes the CB-19SL and CB-26. Check each product page for current dimensions, airflow specifications, electrical requirements and features.
What do automatic swing louvers do?
Swing louvers move back and forth to change the direction of outgoing air, helping spread airflow across a wider area than a fixed louver position.
How does COOLBREEZE cool the air?
Warm air is drawn through wetted evaporative media. As water evaporates, heat is removed from the incoming air before the fan moves that air into the surrounding space.
Does COOLBREEZE work like an air conditioner?
Not like refrigerated air conditioning. COOLBREEZE uses direct evaporative cooling, so performance depends strongly on ambient temperature, relative humidity and airflow.
Does COOLBREEZE need ventilation indoors?
Direct evaporative cooling generally works best with a supply of fresh air and a path for warmer, moisture-laden air to leave the space.
Where can COOLBREEZE coolers be used?
Depending on the model and operating conditions, applications can include garages, workshops, warehouses and suitable open-air or well-ventilated spaces.
How do I choose between the CB-19SL and CB-26?
Compare the size and layout of your space, desired airflow, typical temperature and humidity, water access, electrical requirements, placement and each model's current specifications.
