Johnson Air-Rotation® HVAC Systems

Since 1921, Johnson has been building Air-Rotation units for the system they created. It is still the most efficient method for cooling and heating large open spaces.  The Air-Rotation® system eliminates the need for expensive duct work that can interfere with overhead space. Any single zone space of at least 10,000 square feet with ceiling height of 25 feet or greater, is an Air-Rotation® candidate. One Air-Rotation unit can handle up to 150,000 square feet of floor space. Proprietary air foil axial fans minimize horsepower and noise.

The ground level mounting eliminates roof penetrations, reduces structural costs, allows ground level service and maintenance, and reduces installation expense over roof mounted systems. DX cooling is achieved with Daikin condensing units. Chilled water and ammonia cool are also available. Heating can be electric, gas, oil, steam or hot water. Outside air management including economizer are optional. Dehumidification can be achieved thru the Air-Rotation® system for any application.
