Nordyne is reintroducing its light commercial line of commercial heating and air conditioning products under the brand name “Mammoth,” a sister company to Nordyne. The newest Mammoth light commercial products are single packaged gas/electric units, available in 3- through 15-ton capacities. These high-efficiency units can be installed on the roof or on a slab and have a convertible airflow design for simple installation. The 12.5- and 15-ton units are scheduled to be available in May 2004.
