The Dry-O-Tron® DKV Series of vertical make-up air dehumidifiers have models, which can be used for right- or left-corner installations because both designs use only two sides for service accessibility and supply air discharge. The series has eight sizes ranging from 470 to 8,000 cfm, all with air-cooled or water-cooled capabilities. A heat pump option is available on water-cooled units. Half of the line is less than 79 inches to accommodate standard 30-inch by 80-inch doorways, says the manufacturer. Other features include a side drain and a compressor location that is out of the airstream.
