The CB-28 is a medium-duty commercial-grade cooler that is wellsuited for large industrial space cooling. When temperatures rise and you’re looking for a cost-effective cooling solution, look no further than Cool Boss. The CB-28 evaporative cooler puts out big air - exactly what you’d expect from the world-leader in commercialgrade cooling technology. Use it indoors or out and help turn summer to winter with just everyday tap water. Even though the CB-28 is equipped with a whopping 80-gallon auto-refilling reservoir, because of its abundant water-holding size, it can literally run for hours without the need for refilling, just in case you’re using it where no garden hose is available. With an air delivery of 9020 CFM and coverage of 2,125 square feet, it’s no wonder that the CB-28 is one of our favorites and our customers’ too. Due to OSHA law, employers must have their workplaces be free from heat exposure risks. With Cool Boss you can keep your workers healthy and productive. Cool Boss evaporative air coolers provide instant comfort solutions by using water evaporation to reduce surrounding temperatures without consuming large amounts of energy. This eco-friendly technology allows you to instantly chill areas at a fraction of the cost of traditional air cooling methods. The Cool Boss CB-28 is equipped with four Honeycool™ evaporative media pads that act like a sponge and soak up water, kind of like a pre-chiller for the incoming air. The resin-covered honeycomb allows air to pass through which results in evaporation. This phase transition of liquid water to water vapor turns hot stuffy air into fresh cool awesomeness. Variable fanspeeds and water-flow controls allow you to precisely deliver just how much cool air you need.
