What is a Johnson Air Rotation® System? Heating Specifications for Heating Heating Unit Features Heating Efficiency Comparison Cooling Specifications for Cooling Cooling Unit Features Cooling Efficiency Comparison Heating & Cooling Specifications Unit Features Efficiency Comparison Johnson Air Rotation®  Optional Features Industry-Specific Applications Heating and Cooling Efficiency Comparison In a single unit, a Johnson Air Rotation® System can deliver up to 7 million MBH, 500 tons of cooling and 200,000 CFM. A single unit can condition a 100,000-square-foot space and maintain temperature and humidity with in 1 degree and 1 percent relative humidity. The system: Uses 70% less fuel than unit heaters, infrared, rooftops or direct-fired heating units. Uses 70% less horsepower and 70% less electricity to heat or cool warehouses, distribution and manufacturing facilities Speeds the entire construction process because it may be installed at any time-even at the end of construction-and there are no special requirements such as roof loads, structural support, roof penetrations, ductwork or supplemental paddle fans. Can be installed by three people in less than a half-day. To read a case study about Heating Efficiency, click here. To read a case study about Cooling Efficiency, click here.
