Dynamitron® SF6-FREE Project

Meet us at IMRP 2019

About the SF6-Free Project

A greener Dynamitron®

SF6 is one of the most powerful greenhouse gases. In the Dynamitron®, it enables to sustain very high DC voltage. This project aims at demonstrating and validating economically viable climate-friendly alternatives to SF6 in order to significantly decrease the Dynamitron® carbon footprint.

Promoting climate-friendly insulating gases

SF6 remains the most common insulating gas used in high voltage applications. The knowledge generated in this project will contribute to the development and deployment of SF6 alternatives in the power sector.

A collaboration across sectors

The SF6-Free project is a partnership between IBA, General Electric and the University of Manchester rooted in their common commitment to the environment and the community. The project has been awarded funding at 60 percent of the total costs of EUR 3 million through LIFE 2017 program from the European Union.

Dynamitron® Accelerator

The Dynamitron® is the industry standard for reliable, safe and economical E-beam accelerators.  
The operating principle is very simple. Electrons are generated by a heated filament in an eSource. A voltage gradient draws the electrons away from the eSource and accelerates them through a beam tube. As the high voltage beam of electrons passes from the beam tube and through the scan magnet, an oscillating magnetic field sweeps the beam back and forth across the scan window.
Dynamitron® accelerators are medium energy accelerators used primarily in crosslinking applications and producing electron beam with an energy up to 5  MeV and 160 mA  

With more than 150 machines installed worldwide today, it is the most widely used industrial accelerator in the world for the following applications:

  • Polymer Crosslinking
  • Heat Shrink Products (Tubing or Sleeving)
  • Wire and Cable
  • Sterilization of Medical Devices or other items
  • Composite Materials Curing
  • Food Preservation
  • Aseptic Packages
  • Pollution Control
  • Semiconductors
  • Tire and Rubber
  • PEX-c Tubing
  • Coloration of Glass and Gemstones
