Cool Boss doesn't treat safety as an afterthought. Select models incorporate certified electrical components, protective power connections, durable housings and practical features that help reduce common operating hazards. It's all part of delivering refreshing evaporative cooling with the confidence that comes from equipment engineered for real-world use.

GFCI Protection. Electrical Safety Built In.

Electricity and water demand careful engineering, especially in equipment that uses both to produce cooler air. That's why Cool Boss equips its COOLBLAST Series evaporative air coolers with Ground Fault Circuit Interrupter (GFCI) power cords designed to detect electrical ground faults and interrupt power when one occurs. This added protection helps reduce the risk of electric shock during normal operation.

The CB-16, CB-28 and CB-36 also carry UL certification, demonstrating that the equipment has been evaluated against applicable safety standards. Combined with properly grounded electrical connections and manufacturer-specified operating procedures, these features provide an important foundation for safer cooling. Cool Boss brings serious attention to electrical protection without making the equipment complicated to use.

Automatic Water Controls. Protection That Thinks Ahead.

A steady water supply is essential for effective evaporative cooling, but an overflowing reservoir can create unnecessary problems. Cool Boss addresses that concern with automatic water source shutoff technology on compatible models, using a mechanical float valve to stop incoming water once the reservoir reaches its designated fill level. It's a straightforward safeguard that helps prevent overfilling while making continuous water connections more convenient.

Select Cool Boss models also incorporate low-water warnings or automatic low-water protection to help operators manage insufficient reservoir levels. These features help protect cooling components and reduce the need for constant monitoring throughout the workday. Together with accessible water level indicators and convenient flow controls, they make water management simpler and more predictable.

Built Tough. Designed to Stay Put.

A portable evaporative air cooler needs to move easily when you want it to and remain securely positioned when you don't. Cool Boss combines durable housings with heavy-duty swivel casters that make it easier to reposition equipment around automotive service bays, warehouses and commercial workspaces. Locking casters help keep compatible units in place once they've reached their intended operating location.

Select Cool Boss models also feature high-density polyethylene housings designed to withstand the demands of everyday use. Water guards help reduce unwanted splashing and spills, while thoughtfully arranged components support convenient operation and maintenance. These practical design details make a difference in environments where people, tools and equipment are constantly on the move.

Clear Controls. Fewer Surprises.

Knowing what your equipment is doing is an important part of operating it responsibly. Cool Boss digital control panels provide accessible operating information, including fan settings, timer status and low-water warnings on compatible models. Clear displays and intuitive controls make it easier to monitor the cooler and adjust its operation without unnecessary guesswork.

Programmable shutoff timers add another layer of convenience by allowing select units to power down after a designated operating period. Wireless remotes let users make adjustments from a distance, while conveniently located control panels keep essential functions within reach. Cool Boss puts practical operating information and control where operators need it.

Safety Engineered into Every Workday.

From GFCI electrical protection and UL certification to automatic water shutoff and locking casters, Cool Boss brings practical safety engineering to evaporative cooling. These features are designed to help operators manage the everyday demands of busy commercial and industrial environments while enjoying powerful, refreshing airflow. Actual equipment features vary by model, but the commitment to thoughtful design runs throughout the Cool Boss lineup.

Proper setup, adequate ventilation, routine maintenance and following the operating manual remain essential parts of safe evaporative cooling. Cool Boss provides the equipment and guidance to help users make informed decisions about installation, operation and care.
