OOTR = Ozone Output Test Report

The OOTR is a carefully designed table of very important data which is essential for the correct and safe operation of your ozonation equipment. It is important that all end users of our ozonation equipment know how to read the OOTR and how to interpret data in the OOTR . The OOTR is divided into two sections:

  1. Manufacturer's Information section
  2. Ozone Output Test section

OOTR Figure 1

Each ozone generator is individually tested and calibrated. The 1st OOTR section provides information which will be needed for future references and/or services of the ozone generator. The most important is the serial number of the unit. Please, make sure that serial number displayed in the OOTR matches the serial number on the ozone generator. Contact the supplier of the equipment if numbers are different. We will gladly provide you with the correct OOTR.

The results of the ozone output testing are displayed in the 2nd OOTR section. It is important to point out that ozone output varies with the Flow of Oxygen going through the system and with the Ozone Concentration Regulator Setting.

OOTR Figure 3

Oxygen Flow Regulators have flow rate marked in fractions of the liter - 1/32, 1/16, etc. In order to allow easy volume and dosage calculations OOTR lists flow rate in fractions of a liter as well as cc/min ( = ml/min).

1/16 LPM = 62 cc/min or 62 ml/min
1/4 LPM = 250 cc/min or 250 ml/min
1 LPM = 1000 cc/min or 1000 ml/min

OOTR Figure 4

Selection of Oxygen Flow should be the first step when preparing the ozonation equipment for any application. It is obvious that 1/32 LPM (31cc/min) setting will deliver the lowest flow (smallest volume of the gas discharged within one (1) minute). Setting 1/16 LPM will deliver 62 cc/min and so on. Oxygen Flow Rate is adjusted by rotating the "end piece" of the Oxygen Flow Regulator attached to the oxygen tank. (Example - 1/16 flow rate /62cc/min)

OOTR Figure 5

When the selection of the oxygen flow is done we can start to focus on second step. The position (#1 - #10) of the Ozone Concentration Regulator will determine concentration of ozone gas produced. This regulator changes the frequency of the high voltage discharge.

OOTR Figure 6

Low ozone concentration is produced when oxygen is exposed to low discharge frequency (low settings) and high ozone concentration is produced with high frequency of the discharge (high settings). "Cross-reference" of the Oxygen (ozone) Flow and the setting of the Ozone Concentration regulator will determine the Ozone Concentration produced. (Example: 1/16 Flow & #4 Concentration Regulation => 36 gamma =>36µg/ml => 36 mg/l)
