AboutCascade e-Ion Devices

The Cascade e-Ion Plasma™ Source produces a plume containing ions, electrons, radiation and hot gas.  It is a versatile tool with many possible applications, especially in implementations requiring minimization of the heat affected zone. Its rapid heat-up time also makes e-Ion Plasma™ powered devices great for general heat treating, RTP replacements, photonic applications and dozens of other highly specialized applications. e-Ion Plasma is preferrable to chemicals for mitigating dross in an aluminum melting process.

The Cascade e-Ion's Wide Area Plasma technology allows for use as an energy efficient plasma covering of nitrogen.

Emissions, Health & Environment

  • Likely to produce CO2, SO2 and soot
  • Uses combustion gas inputs of fuel and air, commonly requiring plumbing
  • Typical 20,000 BTU/hr burners produce about 22 moles of greenhouse gasses per hour
  • Fossil fuel powered combustion often leads to toxic byproducts such as Carbon Monoxide
  • Surfaces impacted by flame may be contaminated with small size soot-like particles
  • CleanElectricFlame™ technology produces no CO2, SO2 or soot as a byproduct
  • No toxic emissions.  Air is typical input.
  • Electricity powered, no plumbing or piping needed
  • No venting required
  • Uses only air input, no other gasses
  • No greenhouse gasses
  • Air to Air.  It's like changing your combustion flame to an electric flame
  • Highly efficient, saving on energy costs
  • Non-toxic
  • No residues left because of process
  • Improves productivity
  • May improve shelf life and quality of products

Process Impact

  • Narrow area impact when requiring intense flame, non-uniform heat application
  • Uniformity requirements may require multiple burners
  • User configurable width of plume
  • Higher efficiency
  • Requires less monitoring, saving on labor costs

Explosion Hazards

  • Highly combustible, volatile
  • Incomplete combustion may be a down-stream fire hazard
  • No combustible gasses used as inputs
  • LIP systems offer integrated over-temperature controls

Energy Efficiency

  • Flames are energy inefficient, with only around 10% of their energy able to be utilized for heat as quantized radiation may dissipate heat
  • Over 90% energy efficient
  • Realized energy savings may approach 80%. (A 30kW combustible flame may be replaced by a 6kW plasma plume)

Control

  • Lack of precise control
  • Frequent quality control issues
  • Precise
  • Available built-in safety controls including an over-temperature shut-off

Noise

  • Noisy combustion process
  • Silent

Odor

  • Noxious odor is often noted from combustion byproducts
  • Odorless
  • Clean Process

Cost of Operations

  • Consumes expensive reactant gasses
  • Frequent downtime leads to lost revenues and costs of repair
  • Higher insurance and other costs because of emissions and other flame hazards
  • Uses air and electricity
  • No reliance on supply of combustibles
  • Less downtime, less lost revenues, less cost of repairs
  • Possibility of lower insurance premiums from improved safety


Cascade e-Ion systems allow for continuous sintering (3Dsintering™) or hardfacing without the use of hydrogen. All ionic gasses are of a reducing kind.

Plasma polymerization of many unique polymers and blends and their surface deposits remain unexplored with this new method.
