The Primozone® ozone destruct units come in two different models

Primozone® DM-series

The DM-series has a built-in fan and is the recommended choice when using larger, non-pressurized reaction tanks or basins. The speed of the fan is based on the gas flow to minimize energy usage.

Primozone® DEXF-series

The DEXF-series does not include any fan and is recommended for non-pressurized sealed tanks. The DEXF is delivered with a separate electrical cabinet and can be run in manual or automatic mode.


“Even in a correctly designed ozone water treatment system there will be some residual ozone in the off-gas. With a thermal-catalytic ozone destruct unit any un-reacted vent ozone is efficiently and reliably removed in a very energy efficient way.”

How it works

Thermal catalytic destruct units uses catalytic granular that decomposes the ozone to oxygen. The vent gas is heated before it is passed through the granular to remove humidity and thus improve the performance of the granular.

Main features

  • High ozone destruction efficiency ensuring <0,1 PPM ozone residue
  • Very energy efficient
  • Temperature is monitored and adjusted automatically
  • Manual or automatic operation
