WEDECO PDA/PDO ozone systems

WEDECO PDA/PDO ozone generators are the overwhelming choice of design engineers and end-users worldwide who require reliable, efficient production of large quantities of ozone. This is because each PDA/PDO system have been engineered from the ground up with individual customer requirements in mind. The result is the most compact, cost-effective and reliable ozone generation system available.

Two key features separate WEDECO PDA/PDO generators from the others: The exclusive use of EFFIZON® HP electrode/dielectric technology and the variable frequency technology. These features combined are the basis for an ozone generator with unmatched reliability, production flexibility and low specific power consumptions, all in a compact package that minimizes space requirements and associated facility construction costs.



EFFIZON® Technology
The heart of the WEDECO PDA/PDO ozone system is the EFFIZON®HP ozone generator. Inside the ozone generator vessel, a specific number of tubes are welded between two fixed tube plates serving as grounded electrodes. The EFFIZON® HP electrodes, each consisting of a high voltage electrode, a stainless steel mesh and dielectric glass tube, are placed inside the grounded tubes. Ozone is produced in the gaps between the grounded electrode, the dielectric and the high voltage electrode. ITT Water & Wastewater grants a 10 years warranty for the EFFIZON® HP electrodes.
