Ozone systems are designed as recirculation injection (RI), direct water-injection, and air-injection systems. With recirculation systems, water is continually cycled back to the ozone system for reoxidation at a predetermined level, and returned to the washer for laundry sanitation.
In air-injection systems, ozone gas is injected directly into the catch basin of the washer.
