CO30XE CL30XC Indoor Outdoor Honeywell Swamp Coolers. Honeywell swamp coolers are an effective and green alternative for reducing energy, cooling, and humidifying. Designed to infuse cool air through evaporative cooling and humidity, a swamp cooler doubles as two appliances for environments with humidity below 60%. Additionally, swamp coolers do not contain refrigerants, coolants, and internal compressors, as like air conditioners, and their ability to run on just a water pump and fan makes them an ideal choice for reducing energy costs.
