High-performance atmospheric plasma system

plasmabrush® PB3 – High-performance plasma system
Our plasmabrush® PB 3 is a high power plasma system with Pulsed Atmospheric Arc Technology, for applications that require high performance and rapid processes. Perfectly coordinated components in robust industrial design: 19-inch high power voltage supply PS2000 and plasma generator PB3, connected through a flexible 10m cable for easy integration into every facility.
Thanks to many years of experience in arc load dynamics, fluid mechanics and power electronics, we have developed an atmospheric plasma system which is unique concerning its power density and function. Easy integration into industrial processes and ability to communicate were at the focus throughout the entire development of this universally applicable plasma unit.
Whether in precision cleaning or surface activation, whether in coating or sterilization processes: Our plasmabrush® PB3 fits every process environment – secure and reliable.

Nozzles
There are three different nozzles for the plasmabrush® PB3 atmospheric pressure plasma generator. All nozzles are high performance nozzles which are operated with a Pulsed Atmospheric Arc (PAA®) Plasma Generator (PG31) and pulsed high voltage power supply (PS2000).
The nozzleachieves the following functions:
- focussing of the plasma flame
- acting as a grounded cathode to confine the highpower electric arc
- forming of the cavity to excite the process gas

The most commonly used nozzles in the plasmabrush PB3 so far are the copper nozzles. In processes where the arc is transferred to the substrates, e.g. when cleaning or reducing metal surfaces, the copper nozzles have a very long lifetime*. When polymers are surface activated, however, the arcs dock to the lip of the nozzle, resulting in a shortened service life due to erosion.
In order to extend the lifetime of the nozzles in this popular operating mode, relyon plasma has now developed the special nozzles with a carbide core.
*At this point we expressly refrain from publishing diagrams or tables of the life expectancy of nozzles determined under laboratory conditions. These data were misleading for the consumer, because different process influences as not calculable factors strongly impair the life span.
Carbide nozzles
Due to the material properties of carbide, the carbide nozzles are much more resistant to oxidation and erosion than the standard copper nozzles. Thus, even in the treatment of polymers, a 4-fold higher nozzle lifetime could be achieved than with the copper nozzles. Due to the significantly longer service life of the nozzles, the process now requires less maintenance, is more sustainable and more stable.
Another field of application for carbide nozzles is in the semiconductor industry, where the copper abrasion of standard nozzles is often problematic. This can also be prevented by using carbide nozzles.

Technology
Our plasmabrush® can be adapted to fit process requirements spot-on through a wide variety of accessories. Thus, the quality of your processes and products can be optimized at minimal cost. You only use the components you really need. All components are coordinated perfectly and have been through extensive stress tests. This simplifies maintenance and servicing, and availability is ensured on the shortest possible time scale.
We have consciously adapted our high voltage power supply PS2000 to the independent industrial standard of CanOpen, which makes exceedingly reliable communication possible even under the more severe circumstances an industrial environment can bring about.
A great number of sensors or mass flow controllers operate using the same standard. Every prevalent industrial control worldwide provides a suitable interface. Up to 127 devices can be addressed via CAN node. Every PS2000 high power source can be controlled with a simple DIP switch in the address space of 0 to 99.
PS2000 High voltage source
The PS2000 High voltage source optimised for Pulsed Atmospheric Arc Technology (PAA Technology®). Due to the use of a unipolar pulsed high voltage, the arc is prevented from stabilising at “hot spots” in the nozzle. The latest IGBT switching technology and the use of high quality high voltage components ensure that the source is extremely reliable and e cient. Overloading is also not possible in continuous 24/7 operation. In the event of cable damage or short circuiting during critical operations the control unit intercepts all power fluctuations safely.
The capability of the PS2000 is particularly reflected in the fact that it can operate with variable loads and can effectively pump loads within a large potential range of up to > 12 kV. This special feature ensures continuous ignition performance across a wide power range and for different process gases. The high voltage source is switchable in a range of milliseconds at full load and therefore optimised for timed processes where highly precise timing is beneficial.
All communication is based on the reliable and fast CAN bus. Even in the event of a fault, the communication remains active. Integration into each automated production plant is simple and standardised, even in the case of several high voltage sources.
