Catalytic ozone off gas destructor principal operation is to catalytically convert ozone in a contactor off gas system to oxygen. Ozone is destructed to create safe workplaces; it is very important to destruct any excess or residual ozone in a safe manner. A catalytic ozone off gas destructor is a very common process for destruction of ozone, being cost effective and with a success rate of decomposing at least 99% of the ozone present in a standard atmospheric air stream. These destructors are easy to install, and the only requirement is power onsite and ozone resistant ducting from the contact tank to the destructor inlet. Watertec units are self-contained units which operate under pressure from the contact tanks. Optionally, a specially designed ventilation fan to extract the off gas from atmospheric style ozone contact chambers can be fitted. If the ventilation fan is used, then the entire catalytic reaction takes place under negative pressure in the system, with only the de-ozonised exhaust being under positive pressure. All units are made of ozone resistant material stainless steel 316 or resistant plastics and use catalytic material manganese oxide to destruct the ozone. It is very important to for the minimum temperature to be 10oC as based on the rated airflow for these destructors. Watertec offers a range of sizes from 20m3/hr to 250m3/hr, our equipment is designed for easy and reliable installation and operation without the need to monitor and adjust valves or airflows. If the unit is sized correctly, installed correctly and has regular servicing it will provide many years of trouble-free operation.
Watertec has a second option for ozone destruction and that is through a carbon off gas destructor also none as residual ozone converter, which has proven to be successful in practice over the many years. Ozoniferous spent air in introduced to the chamber underneath the intermediate support, small amounts of water are then separated in the lower section and passed to the drain via an overflow. The ozoniferous air passes upwards through the activated carbon media where the residual ozone is converted. O2 now passes upwards and out of the ozone off gas destructor. Mechanical and chemical destruction created powdered activated carbon which can ignite, it is important if you run a carbon of gas destructor that you replace a minimum of every 12 months.
