The OZONE GENERATOR BMT 802N is a small air-cooled ozone generator for oxygen as the feed gas. The dielectric is plain ceramic. The electrodes are tungsten.

The enclosure of the instrument is an aluminium extrusion profile which acts as a large heat sink. Additionally a fan is mounted externally which also helps in ventilating the internal. Dimensions of the generator are approx. 311 x 170 x 139 mm, not much bigger than a shoe box. The weight is approx. 4.7 kg. Input voltage is 230 VAC, or 115 VAC. Inlet and outlet fittings are for 3 x 5 mm (or 1/8'' x 3/16'') PTFE tubing.

Maximal power consumption is about 80 W, including the 15 W for the fan.

The operating pressure must not exceed 1 bar gauge. Between 0.5 and 1.0 bar gauge (1.5 to 2.0 bar abs), 100 g/Nm3 and 20°C ambient temperature, the ozone production is 4 g/h or more. The maximally obtainable ozone concentration exceeds 250 g/Nm3.

The ozone production decreases with increasing ambient air temperature by approx. 1% per degree centigrade.

The OZONE GENERATOR BMT 802N is a building block. We recommend installation according to the schematic shown below. The generator should be operated at constant pressure, and the flow be adjusted by a throttle valve at the outlet. The pressure relief valve (3) is important for protection from overpressure when the outlet throttle is closed. Flow should be measured on the oxygen side. The filter (1) is important namely for oxygen coming from a PSA and/or when a thermal mass flow meter is used for flow measurement (4).

Measurement of ozone content (e.g. with our OZONE ANALYZER BMT 964) can be made with the total flow passing the analyser. Connecting tubing should be PTFE, even on the oxygen side.

We are ready to assist you in planning the installation of the OZONE GENERATOR BMT 802N.
