Honeywell Evaporative Air Cookers are built to maximize energy efficiency and keep costs low. Warm air is drawn into the Honeycomb Cooling Media. Water pumped from the tank pours over the Honeycomb Cooling Media. As the warm air passes through the media, the water absorbs the heat, naturally cooling and humidifying the air. A fan propels the cooled air out to room. The No Compressor system cools naturally, efficiently and inexpensively.
