Evaporative Coolers
Move high volumes of cooled air through garages, service bays, warehouses and industrial work areas with portable evaporative cooling equipment built for demanding environments.
Evaporative coolers use water evaporation instead of refrigerant-based cooling, making them a practical option for large, open and well-ventilated spaces—especially in hot, dry conditions.

Application
Application
Start with the space you need to cool.
Evaporative coolers vary considerably in airflow, reservoir size, electrical requirements and air-delivery configuration. Match those specifications to your workspace instead of choosing on physical size alone.
Air Delivery
Cooling Capacity
Compare airflow and overall cooling output with the size and demands of the garage, service bay or industrial work area.
Water Supply
Reservoir Capacity
Current Cool Boss models range from compact 15-gallon-class reservoirs through large 115-gallon systems for demanding applications.
Electrical
Power Requirements
Check the available electrical supply before selecting a unit. The current assortment includes both standard 110V and 208–230V equipment.
Air Direction
Airflow & Placement
Consider where cooled air needs to go. Available equipment includes swing-louver, high-velocity and ductable configurations.

Evaporative coolers are a fantastic solution to the issue of overheating in the workplace. OSHA law requires that employers have their work areas be free of heat exposure risks, and an evaporative cooler is a great way to keep temperatures down. Evaporation is what cools the air, meaning this coolers are an eco-friendly alternative to traditional AC. No refrigerants required. They also only need a minimal amount of energy to run - about a dollar a day. The hotter it is, the more effective these air coolers become. They are perfect for industrial settings. Cool Boss is capable of cooling areas within 2,500-2,800 sq.ft., and certain Cool Boss models even come with a negative air ionizer that causes harmful airborne particles to stick to walls and floors so they can be cleaned easily. In areas where the air is very dry you’ll find that the coolers are capable of dropping the temperature by 20+ degrees. In other areas they can still lower the temperature but it won’t be as effective as if it were dry conditions. Wrenchers will find you the best evaporative cooler so you can save money and beat the heat.
Buying Guide
Choosing an Evaporative Cooler
Start with the size and conditions of the area you need to cool, then compare airflow, reservoir capacity, electrical requirements and air-delivery features. Larger isn't automatically better—the goal is to match the cooler to the workspace.
Check Reservoir Capacity
Tank capacity varies substantially across the Cool Boss lineup, from compact portable models to equipment with large reservoirs for demanding work areas.
Verify Available Power
Check voltage and electrical requirements before purchasing. The current assortment includes equipment designed for different shop power supplies.
Plan Where the Air Goes
Consider where the cooler will sit and where cooled air needs to be directed. Air-delivery configuration can be just as important as overall output.
Evaporative Cooling
Water. Airflow. Evaporation.
Evaporative coolers use water evaporation to cool moving air rather than relying on refrigerant-based cooling. The existing Wrenchers category specifically identifies hot, dry conditions as the environment where this type of cooling is most effective.
Water
Supply the Reservoir
Water stored or supplied to the cooler supports the evaporative cooling process.
Evaporation
Air Passes Through the System
The cooling process uses evaporation rather than a traditional refrigerant-based air-conditioning cycle.
Airflow
Move Cooled Air Into the Workspace
High-volume airflow distributes the cooled air into the garage, service bay or work area.
Compare the Specifications
Don't choose on cabinet size alone.
The current Cool Boss assortment includes significant differences in airflow, tank capacity, voltage and air-delivery features. Those specifications give you a better basis for comparison than physical size alone.
Airflow
Compare CFM where it is specified for the model.
Reservoir
Check water-tank capacity against the intended application.
Voltage
Verify that the cooler matches the available electrical supply.
Air Direction
Look for features such as swing louvers or targeted air delivery.
Mobility
Consider where the cooler needs to operate within the work area.
Accessories
Check available accessories when targeted or ducted airflow is needed.
Current
Range
Range
Cooling equipment for different-sized work areas.
The category spans smaller portable Cool Boss units through high-output industrial evaporative coolers, along with equipment designed around different tank capacities and air-delivery requirements.
Compact Equipment
Portable Cooling
Smaller Cool Boss models provide portable evaporative cooling in a more compact footprint for targeted work areas.
Higher Capacity
Large-Reservoir Coolers
Larger models increase water capacity for applications that call for more substantial evaporative cooling equipment.
Air Distribution
Swing-Louver Models
Available configurations include swing louvers designed to help distribute airflow through the intended work area.
Targeted Airflow
Ducting Options
The current assortment includes a flexible ducting kit for the CB-16L when cooled air needs to be directed into a more specific workspace.
Operating Conditions
Climate matters with evaporative cooling.
Evaporative cooling performance depends on environmental conditions. The existing Wrenchers category specifically notes that these coolers perform most effectively when the surrounding air is hot and dry.
Important Selection Factor
Consider the humidity in your work environment.
Evaporative cooling relies on evaporation, so environmental conditions should be part of the equipment-selection process.

Questions
Questions
Evaporative Cooler FAQ
Key considerations when comparing evaporative cooling equipment for a shop or industrial workspace.
What is an evaporative cooler?
An evaporative cooler uses water evaporation and moving air to provide cooling rather than using refrigerant-based cooling like traditional air-conditioning equipment.
Where do evaporative coolers work best?
The existing Wrenchers category identifies hot, dry conditions as the environment where evaporative coolers are most effective. Environmental humidity should therefore be considered when choosing this type of cooling equipment.
What should I compare when choosing a Cool Boss?
Compare the specifications shown for each model, including airflow, reservoir capacity, voltage and air-delivery features. The current assortment varies significantly across each of those areas.
What reservoir sizes are available?
The current category includes compact models with approximately 15-gallon reservoirs as well as substantially larger equipment. The CB-36H listing, for example, specifies an auto-refill 115-gallon reservoir.
Do all Cool Boss evaporative coolers use the same voltage?
No. Electrical requirements vary by model. For example, the current CB-26SL listing specifies 110V, while the CB-26SLH listing specifies 208–230V. Always check the individual product specifications before purchasing.
Can cooled air be directed to a specific work area?
Some models include air-direction features such as swing louvers, and the current category also includes a CB-16 Ducting Kit for directing air from the CB-16L into a targeted workspace.
Can Wrenchers help me choose an evaporative cooler?
Yes. If you're comparing airflow, tank capacity, electrical requirements or different Cool Boss models, contact Wrenchers for product assistance.
