Abstract

A laundry ozone injection system includes an ozone generator connected to an ozone distribution manifold having a plurality of manifold outlets connected through ozone valves to ozone injectors associated with washing machines of a laundry plant. Each washer has water cycled therefrom by a pump, through the ozone injector, and back to the washer chamber. A washer cycle controller of each washer is interfaced to a local interface module along with a pump motor. The local interface modules are interfaced to an ozone distribution controller or main controller which is also interfaced to the ozone valves. The current washer cycle of each machine is detected by its local interface module and communicated to the main controller which controls the rate of ozone production of the ozone generator, the activation of the pump motor, and the opening of the ozone valve of a washer in accordance with the currently detected washer cycle to thereby control the delivery of ozone to the washer.
