Cold Plasma Odor Control Plasma Injector


Odor control by the Plasma-Injector is based on high speed oxidation. The oxidized molecules cannot be detected organoleptically, hence they do not bother the observer. The Plasma-Injector system consists of a stainless steel cabinet with Plasma Reactors.


Ambient air is radiated and, as a result, the oxygen and water vapour molecules are dissociated.

This transition is the first step in a process where eventually an extremely reactive gas is formed comprising a mixture of unstable oxygen atoms, ions, radicals etc., with elevated electron energy levels. This gas, often called 'active oxygen' has the ability to execute a high speed oxidation process with odor components after injection through the polluted air. The odor molecules will lose the faculty of exciting a man's sense of smell.


After implementing 21 years of experience with world market leaders like Cargill, PepsiCo, Biomar, International Flavors & Fragrances, etc.:

  • High odor removal efficiency with variable power supply 0-100%.
  • No mechanical wear.
  • No supply of water, chemicals, absorbents,  biomaterial etc.
  • No waste at all.
  • Low investment and operational costs.
  • No impact from process fluctuations like dust, temperature, humidity etc.
  • No impact on the production process, does not obstruct process airflow.
  • Almost no maintenance required: 1 hour per 3,000 hours of operation.
  • Lower energy consumption than any other odor control system.
  • Simple operation (only on/off).
  • Modular design, easy to adapt to any airflow .
  • Very compact: dimension for example 17,000 m3/h (10,000 cfm)
  • WxHxD= app.     0.40x0.70x0.75m (16x28x30 inch).

The Plasma-Injector odor control solution in 3 steps:

  • Pilot test at your site to determine odor reduction as a function of energy.
  • Calculate Stack Dilution as a function of the distance from your stacks. Emission parameters: airflow, temperature, stack height, etc.
  • Dispersion modelling: calculating the distance from your stack of the Odor-Isometrics with the Detection Threshold (1 odour unit/m3) before and after treatment.

Step 1: Perform pilot testing, example

  • A= untreated air is 20,000 ou/m3
  • B= treated after Plasma-Injector 2,000 ou/m3


Step 3: Dispersion Modelling of Detection Threshold (DT=1 ou/m3) before and after treatment with Plasma-Injector.

  • A: Untreated airflow 17,000 m3/h (10,000 cfm) and odor concentration 20,000 ou/m3. The average radius from the stacks = 4,000 meter.
  • B: Treated air. Odor concentration is 2,000 ou/m3 is 90% efficiency at 6 kW. The average radius from the stacks = 500 meter


A small cabinet 12’x28″x30″ = 30x70x75 cm injecting 2,000 m3/h = 1,200 cfm of activated oxygen, converted from clean ambient air with the Plasma-Injector, into your stack with process airflow 20,000 m3/h = 12,000 cfm and controlling the odor with only 6 kW. No chemicals, biomaterial, masking agents or any obstruction in the process airflow.
