Initially, a series of short tests
(5, 10 and 15 minutes of operation) were conducted to compare the short-run ozone production capacity of the EPL unit with a ceramic plate based unit. In each test, it was found that the production capacity of both units was practically identical.
Subsequently, a three-hour test was conducted. As expected, the ozone production of the ceramic plate unit began to tail off, and continued to reduce over time. Conversely, the EPL unit continued to increase the measured ozone levels in the area for the duration of the test.
