Advantage
and Value

 
Higher Performance in Open Environment Surface Treatments

TPS uses nanosecond pulsed power to unlock previously inaccessible capabilities of plasma. The result is exceptional increases in benefits including improved performance and reduced processing costs in open environment (atmospheric pressure) applications.

TPS Transient Plasma technology offers significant advantages over conventional plasma systems using AC/DC/RF or other excitation sources.

Shorter pulses produce heightened electron energy resulting in dramatic increases in chemical activation.

More of the pulse energy is invested in creating energetic electrons instead of heating the bulk surrounding gas.

The TPS
Difference

 
Transient plasma is low-temperature plasma produced by nanosecond (ultra-short duration) electrical pulses. The system enables superior cleaning and activating of surfaces to improve bonding and adhesion of coatings in atmospheric and low-pressure applications.

Nanosecond pulse power is very different from conventional RF power. By delivering an ultra-fast rising voltage pulse, nanosecond pulse power maximizes electron energy resulting in a higher degree of ionization and richer plasma output.
