TIGRES T-JET technology 
Corona for heat-sensitive surfaces

TIGRES T-JET offers indirect corona treatment with very little heat being transferred to the surface. This technology is ideal for pretreating heat-sensitive substrates.

The corona discharge is generated inside of the head between two electrodes and conveyed onto the surface by an air stream.

Whether using a single head for a processing width of 20 - 60 mm or using multiple heads lined up together for wider applications - this proven technology offers a solution for many different purposes. The innovative feature of this technology is the modulated, high-frequency electrical voltage. One generator can supply up to two nozzles.

Different process gases such as nitrogen can be used here, too.

The technology can be adapted to any material width by varying the number of heads. Depending on the process parameters, the plasma treatment has an effective range of 10 - 40 mm.

Process integration

The supply lines to the Corona T-Jet heads can run parallel or perpendicular to the head.


  • Single head
  • Two heads on one generator

 Essential features of T-JET technology

The electrode generates a discharge (corona) that an air stream conveys onto the surface to be treated.

  • A single generator can feed one single head or two heads
  • Extremely powerful due to high-frequency modulation
  • The system is suitable for all non-conducting substrates
  • Proven, durable and inexpensive system solution
  • Integrated fan means no compressed air is needed
