Johnson Air Rotation® Systems
Air Rotation systems supply conditioned air to a large open spaces using high volume, low velocity, air-circulation. The conditioned air may be heated, cooled, humidified, dehumidified or supplemented with outside, fresh air as defined by the requirements of the application. Air Rotation is a comprehensive conditioning system with general ventilation that results in vertical temperature control, low energy and maintenance costs, with no stratification.
IFB & VIFB coil controls air temperature while full steam pressure or water flow is maintained in the coil at all times. Regardless of variations in the inlet air temperature, the preset discharge air temperature is held constant. These systems are ideally suited for make-up air, combustion air make-up, air conditioning preheat and heating and ventilating units.
Multi-stage face and bypass coils provide greater temperature control flexibility and offer more dependable VAV operation. They also offer greater freeze protection and ease of installation than any other coil available.
