How Ozone Destruct Units Work
Ozone destruct units are essential in ozone systems to mitigate the risk associated with the excess ozone, which can be harmful above certain concentrations. There are different types of ozone destruct units designed for various applications:
High Concentration Ozone Destruct Units: These are used when ozone concentration is above the level that’s immediately dangerous to health (5 ppm). They are passive devices, meaning they require an external airflow source to operate.
Ambient Air Ozone Destruct Units: These are used to remove ozone from occupied spaces or areas where ozone levels need to be reduced. They come with integrated fans to move air through the unit.
Wet Air Stream Ozone Destruct Units: These units are specifically designed to handle air streams from water applications, such as ozone contact tanks, where the air is moisture-laden. They are often equipped with heaters to prevent moisture from condensing on the catalyst.
Dry Air Stream Ozone Destruct Units: These are suitable for air streams without condensation, with normal ambient humidity levels up to 85%.
The destruction of ozone is achieved through a catalytic process where ozone (O3) is converted back into oxygen (O2). The catalyst used is typically a proprietary material, with granular media used in high concentration units and honeycomb materials in ambient air units.
Benefits of Ozone Destruct Units:
Safety and Compliance: By reducing ozone concentration, these units help prevent exposure and ensure compliance with environmental regulations.
Efficiency: The units can convert ozone into oxygen thermally or catalytically, with the latter being more energy-efficient and cost-effective.
Environmentally Friendly: The units operate without emitting toxic gases, such as carbon monoxide or carbon dioxide.
Durability: The catalysts, like Carulite200, are durable and resistant to degradation, which means they do not require frequent replacement, reducing operational downtime.
Cost-Effectiveness: While the catalysts eventually need replacement, their non-consumable nature and long lifespan make ozone destruct units a cost-effective solution.
Environmental Protection: Converting excess ozone into oxygen before releasing it into the atmosphere prevents environmental contamination.
In summary, ozone destruct units are critical components in ozone systems for ensuring safety, compliance, and environmental protection. They operate efficiently to convert harmful ozone into harmless oxygen, providing a solution that’s both effective and cost-efficient.
