Evaporative Air Coolers

Fight the heat anywhere with a Cool Boss evaporative air cooler. Deliver fresh, high-volume airflow without the high energy bill.

Why Choose a Cool Boss Evaporative Air Cooler for Your Commercial or Outdoor Cooling Needs?

When you're working in a hot warehouse, patio, or garage, traditional A/C isn't always practical or affordable. Cool Boss evaporative air coolers pull in the surrounding hot air, pass it through cool water, and push out a steady breeze that refreshes the space around you. There's no complex setup, no need for permanent installation, and they use way less power than regular air conditioners. Just place it where you need it and stay cool for hours.

Cool Boss - Evaporative Coolers

Cool Boss industrial-grade evaporative air cooler

Industrial-Grade Cooling

Cool Boss coolers push out high-CFM airflow that cuts through hot, stale air in places traditional A/C can't reach, like open bay doors, loading docks, job sites, or shop floors.

Lower Energy Costs

Cool Boss evaporative coolers use water and standard power to cut electricity use by up to 75% compared to central air. Most units cost just $1 per day to operate. We recommend using mineral treatment to prevent buildup and keep your system running smoothly long-term.

Cool Boss evaporative air cooler airflow coverage for large areas

Effective for Large Areas

Whether you're cooling 600 square feet or 6,000, there's a model that fits the job. Cool Boss can handle anything from small workstations to full production bays.

Efficient Water Use

Each unit uses Honeycool™ media to soak up and hold water like a sponge and deliver hours of consistent airflow with fewer refills. The resin coating also improves durability for a long-lasting cooling solution.

Got questions? Ask us here.

Are evaporative air coolers effective?

Absolutely! They’re especially effective in large, open spaces where traditional A/C doesn’t make sense. Evaporative coolers work by pulling hot air through water-soaked pads, then pushing it out as cooler air. In dry or semi-dry spaces, they can drop the surrounding air enough to make a hot warehouse, garage, or patio feel comfortable again.

Do swamp coolers work in 100 degree weather?

They can, but their effectiveness depends on the humidity. In dry heat, swamp coolers perform extremely well, even on triple-digit days. If the air is already humid, the cooling effect won’t be as dramatic, but you’ll still get strong airflow and noticeable relief if you’re sitting near the unit. Many large evaporative coolers move so much air that they create a strong breeze, even when temps hit 100°F or higher.

What’s the difference between an air cooler, an evaporative air cooler, and a swamp cooler?

They’re actually the same thing. “Air cooler,” “evaporative air cooler,” and “swamp cooler” all refer to devices that use water evaporation to cool hot air. The only real difference is that the name “swamp cooler” is the older, informal term, while “evaporative cooler” is more commonly used for modern, high-performance models like those used in warehouses, shops, and commercial spaces.

What are the highest-rated evaporative coolers?

The best evaporative cooler depends on the space you’re trying to cool. For small areas like garages, patios, or personal workstations, models like Cool Boss’ CB-12SL, CB-14SL, or CB-19SL are compact, efficient, and easy to move.

For bigger spaces like warehouses, production floors, or job sites, higher-powered models like the CB-28HV, CB-36, or CB-28L offer incredible airflow, large tanks, and extra features like LED lights or Bluetooth audio. It really all comes down to your square footage and how much cooling power you need.

On top of that, you’ll avoid monthly utility spikes and ongoing maintenance fees. With evaporative cooling, all you need is water, an outlet, and a few minutes to get started.

How much does an evaporative cooler cost?

Most commercial-grade evaporative coolers range from around $600 to $5,000, depending on the size, airflow, and features. That might sound like a lot until you compare it to installing an industrial A/C system, which can easily cost tens of thousands for equipment, ductwork, and installation alone.

What are common materials for evaporative coolers?

All you really need is water and a standard power outlet. That’s it. Most units plug into a regular 110V outlet and work with either a built-in tank or a garden hose for continuous water supply. You don’t need any refrigerants or special hookups, making evaporative air coolers an easy and effective solution to beat the heat.
