01
Evaporative Media
Water-saturated media creates a large wet surface where incoming air can interact with water and support evaporation.
Why Cool Boss
Performance Built Around Airflow.
Cool Boss combines evaporative media, high-volume fan airflow and portable design to deliver practical cooling for hot, ventilated workspaces.
Evaporative Cooling Performance
It's about more than moving air.
Effective evaporative cooling depends on the relationship between water, airflow and the surrounding environment.
Cool Boss draws warm air through water-saturated evaporative media. As water evaporates, heat is removed from the incoming air before the fan distributes that air into the surrounding workspace.
High-volume airflow then helps move that evaporatively cooled air through garages, service bays, warehouses and other large, ventilated areas.
Actual performance varies with the model, ambient temperature, relative humidity, ventilation and workspace layout.
Performance Fundamentals
Three parts working together.
Cool Boss performance starts with an effective evaporative surface, substantial airflow and operating conditions that support evaporation.
02
High-Volume Airflow
Fan-driven airflow pulls air through the media and distributes evaporatively cooled air into the surrounding workspace.
03
Proper Conditions
Temperature, humidity, fresh-air supply and ventilation influence how much evaporative cooling can occur.
Honeycool™ Evaporative Media
Give evaporation room to work.
The evaporative media is where much of the cooling process takes place.
Honeycool™ media absorbs and distributes water across a large surface area while allowing incoming air to pass through.
As that air moves across the wet media, water can evaporate into the air stream. The evaporation process absorbs heat from the incoming air before it leaves the cooler.
Blue Flex™ Axial-Flow Fans
Move more air through the workspace.
Evaporative cooling needs airflow to move conditioned air beyond the cooler itself.
Cool Boss Blue Flex™ axial-flow fans are designed to move high volumes of air through the evaporative media and outward into the surrounding area.
That airflow is particularly useful in larger, open and ventilated environments where cooling needs to reach active work areas rather than remain concentrated around a fixed vent.
The Cooling Process
From hot air to cooler airflow.
Evaporative cooling uses a straightforward physical process rather than a compressor-based refrigeration cycle.
01
Saturate the media
Water is circulated through the evaporative media, creating the wet surface required for evaporation.
02
Pull in warm air
The fan draws incoming air through the wet media, where evaporation absorbs heat from the air stream.
03
Deliver cooler air
The fan pushes the resulting evaporatively cooled air outward and into the surrounding work area.
Real-World Performance
Conditions make a difference.
Higher incoming air temperatures can provide greater potential for useful evaporative cooling.
Drier air can accept more moisture, generally increasing evaporative cooling potential compared with humid air.
Fresh-air supply and an outlet for humidified air help maintain conditions that support continued evaporation.
Doors, walls, equipment and other obstructions influence how effectively airflow travels through a space.
Temperature reduction is not a fixed number.
Evaporative cooling performance changes with ambient temperature, relative humidity, airflow, ventilation, model selection and operating conditions. Published maximum performance figures should not be interpreted as the result every application will experience.
