Our odour control system

The Aerox-Injector is a highly innovative injection based odour control system that is fitted outside the process gas duct. It has been successfully installed at over 250 locations worldwide in a wide range of industries.

State-of-the-art technology

The Aerox-Injector was developed and engineered by Aerox in cooperation with universities and research centres. It is based on non-thermal plasma injection technology. In short, the compact installation transforms clean air into active oxygen, which then executes an oxidation reaction with the odourous components in the process air flow. The oxidized odour molecules are undetectable by the human nose.

Easy maintenance on odour control system

Only once per 8,000 hours the Aerox-Injector requires 1 day service, without production downtime. The odour control system functions fully autonomous and guarantees optimal and stable odour reduction for the complete period of 8,000 hours. The modular design allows for flexibility and upgrades.

Factory owners are assured of a state-of-the-art technology odour control system with additional benefits such as: 

  • Highest efficiency in odour reduction possible
  • Minimal usage of electricity
  • No requirement for water, gas or chemicals
  • Easy to install, even in existing factories
  • Low total cost of ownership
  • Suitable for all temperature and humidity ranges
  • Only 1 maintenance cycle per year, no process downtime

 Non-thermal plasma technology

The Aerox-Injector is based on non-thermal plasma, an environmentally friendly technology to destroy offensive odour molecules. 

What is plasma?

Plasma is commonly known as the fourth state of matter, alongside liquid, solid and gas. It is made up of ionised gas, which consists of a balanced mix of electrons, positive ions and neutral particles. Because of the highly energetic state of the constituents of plasma, it produces its own electromagnetic radiation. This is one of the differences with ‘normal’ gas.

Non-thermal plasma

Hot plasma operates at very high temperatures between 5000 and 10,000 °C. Cold or non-thermal plasma is less well ionised than hot plasma, and although the electrons are at high temperature, the positive ions and neutral particles are at a lower temperature. Aerox developed plasma modules that generate non-thermal plasma by electricity. Because cold plasma operates at room temperature, relatively little electricity is needed, ensuring a sustainable and cost effective odour solution.

The non-thermal plasma modules transform clean air into active oxygen, which is then injected into the process airflow for oxidation of odourous components.

Injection principle

The Aerox-Injector uses clean ambient air for destruction of offensive odours. The air is pushed through a 3-stage filter. Then the purified air is drawn into the Aerox-cabinet, where it passes through the non-thermal plasma modules. Within the plasma, oxygen and water vapour molecules are split, transforming them into active oxygen. This highly reactive mixture is then injected into the process air exhaust duct.

Odour destruction by oxidation

There is no direct contact between the process air and the generated plasma field. Process air cannot enter the Aerox unit since the injection fan ensures a higher pressure inside the Aerox-cabinet compared to the process air duct. Also the specially designed connecting injection adapter between the Aerox-cabinet and process duct contains non-return valves.

Injection air

The active oxygen in the injection air executes a high-speed oxidation reaction (< 0,5 seconds) with the offensive odour molecules inside the process air. This makes them inoffensive and undetectable by the human nose, solving the odour problem.

Integration of odour destruction system

The Aerox-Injector is a compact industrial odour destruction system, converting only a small air volume with cold plasma into active oxygen. Nevertheless, direct injection allows treatment of high volumes of process air (up to 140,000 m3/h). The injection technology makes it easy to integrate in the production process. No production downtime and no major adjustments to process installations are needed.

Sustainable odour control

The Aerox-Injector is designed specifically with the environment in mind. All it needs is a relatively small amount of electricity. Aerox guarantees a sustainable odour control solution:

  • No fuel
  • No water
  • No chemicals
  • No waste.

 

Low CO2 emission

The Aerox-Injector generates active oxygen to destroy offensive odours using non-thermal plasma or cold plasma technology. One of the biggest advantages of cold plasma, or cold combustion, is that the ionization process starts at room temperature. Normally combustion is achieved at much higher temperatures. Therefore relatively little electricity is required and the CO2 emission remains low.

No fuel required

Our aim is to run the Aerox-Injector on as little resources as possible, keeping the installation as small as possible. Our environmentally friendly odour control system runs completely on electricity and nothing else. By continuous research we keep trying to further lower its energy consumption as well as minimizing its size.

Easy integration

Because our technology is based on the injection principle, it is relatively simple to integrate into the production process without production downtime. No major adjustments are necessary.

No waste flows

Renewal of the plasma modules after 8,000 hours is included in our service contract. We reuse the modules and recycle the other components. We are also proud our Aerox-Injector generates no waste, affluent water or residue chemicals whatsoever.
