For over 90 years, Arizon's Johnson Division has been the leading provider of fuel and energy-efficient heating, air conditioning and ventilation equipment for manufacturing, warehousing and distribution facilities.

Johnson Air Rotation Systems use high volume, low velocity, air-circulation to distribute conditioned air to a large open space. We say "conditioned air" because the air in the space may be heated, cooled, humidified, dehumidified or supplemented with outside, fresh air as defined by the requirements of the space. Air Rotation is a total conditioning system, including general ventilation that results in no stratification, vertical temperature control, low energy and maintenance costs.
