Dielectric Barrier Discharge

A dielectric barrier discharge is a dry method of plasma treatment that doesn't generate wastewater or require drying of the material after treatment.

This technology is used in fuel production, gas scrubbing to reduce harmful emissions, and bulk surface activation for large surface areas or continuous processes.

Plasma is produced by two electrodes with a dielectric between these electrodes to limit the current flow in the plasma. This low-density plasma can be described as Dielectric Barrier Discharge (DBD). 

This method of plasma production is also called silent discharge due to the current limiting dielectric controlling the rate of ionization of the gas.  This relatively low-density plasma produces controlled ionization of the available gas generating little to no detectable sound.  This method of low-level density plasma production is useful in gas plasma processing like ozone generation, gas reforming, and broad area low-level activation processes.

Reforming Gases using Dielectric Barrier Discharge

One of the key principles of using DBD to generate a plasma is that the plasma can be produced at atmospheric pressure and other pressures. This means that you can generate plasma and expose a gas to molecular dissociation without pumping it down inside a vacuum chamber. This molecular dissociation in combination with catalyzation events leads to gas reforming efficiencies difficult to perform by other methods.
gas scrubbing

Gas Scrubbing using Dielectric Barrier Discharge

Another use of Dielectric Barrier Discharge is the process of gas scrubbing for emissions or control of greenhouse gas generation. The ability to dissociate the molecular structure of a gas and recombine it to limit specific molecular emissions or optimize a molecular generation can be possible with Dielectric Barrier Discharge application to gas.

The gaseous monomers are introduced directly into the plasma jet by means of a carrier gas. Therefore, the plasma focuses on the monomer on the surface and polymerizes it.

Plasma System Types

Low Pressure

These systems apply energy to a gas in a vacuum system to produce a stable source of gas plasma.

Atmospheric Pressure

These systems apply air or gas plasma to a small area of a part without treating the entire part.

Custom Industrial

These custom systems enable manufacturers a design that fits seamlessly into their established manufacturing line.

Vacuum Chambers

Many manufacturing processes require high altitude testing or material drying vacuum chamber solutions.
