What is the NOx Filterbox 2.0?

The NOx FilterBox 2.0 is a plug-and-play solution that captures nitrogen oxides (NOx) as a mitigating measure around construction and industrial activities. The NOx FilterBox 2.0 has been tested by TNO for 150 hours at a construction site in the Randstad area and can remove 27 kg of NOx from the outdoor air annually. This number of kilograms depends on the prevailing concentration of NOx in the outdoor air.

The NOx FilterBox 2.0 can be applied in any desired sector for capturing nitrogen oxides. For optimal operation, it is recommended to place the NOx FilterBox 2.0 at a height of 2 to 4 meters with a free intake of outdoor air, for example on a freestanding 20″ container.

Test TNO

The NOx FilterBox 2.0 was tested by TNO for a week at a construction site in the Randstad area. Continuous measurements were taken to determine the intake of nitrogen oxides and the amount of exhaust. The measurements show that the system is indeed capable of capturing nitrogen oxides, especially nitrogen dioxide (NO2). During the 150-hour measurement period, a total of 458 grams of nitrogen oxides were captured. The research was conducted at winter temperatures ranging from 14 to 0 degrees Celsius.

OC Filtration Solutions also provides advice on permit applications and delivers project-specific calculations to expedite this process.

Maintenance

Based on the measurement equipment on the NOx FilterBox 2.0, we can monitor the efficiency of the filter medium. If the filter medium becomes saturated, the filters need to be replaced. We offer maintenance contracts for both monitoring and replacing the filters. Feel free to contact us at 085-064 58 62 for more information.

Waste Management

We dispose of contaminated filters as chemical waste. This waste is processed as calorific fuel in modern waste incineration plants, fitting into a circular process. These waste incineration plants comply with strict environmental regulations and are equipped with selective catalytic reduction (SCR) installations, which remove an average of 90-94% of all nitrogen oxides released during the combustion process. The residual heat generated during the combustion process is often reused as heat/energy.

Steps to request the NOx FilterBox 2.0

For requesting the NOx FilterBox 2.0, only three steps are required:

  1. As the applicant, you will conduct an Aerius calculation.
  2. Based on the outcome of this Aerius calculation, OC Filtration Solutions will have an independent consultancy firm conduct the specific calculation to determine the number of NOx FilterBox 2.0 units needed.
  3. With the substantiated solution, you, as the applicant, can proceed with the permit application process.
