Rotation for surface treatment
Using dry, oil-free compressed air, the rotary unit – equipped with two opposing PlasmaBeam nozzles – effortlessly handles 2D surface treatment on a scalable basis. This enables exciting solutions for critical manufacturing processes. Pre-treatment of films in battery manufacturing or the processing of solar cells and modules in PV production are just two of countless application examples. The system comprises the supply unit, gas and power lines in flexible tubing, plus the RT. High treatment speeds on the surface to be cleaned or activated are achieved continuously with the PlasmaBeam RT from Diener electronic for widths of up to 120 mm.
RT – things are really hotting up with 2 plasma jets
The atmospheric plasma system PlasmaBeam RT comprises the basic components of a power supply unit and a plasma generator. The plasma generator receives the high-voltage and process gas supplies from the power supply unit via a supply line. An arc discharge is initiated between high-voltage electrodes within the plasma generator. The plasma generated is expelled via two rotating plasma nozzles.
The PlasmaBeam RT from Diener electronic offers atmospheric plasma treatment across the surface. The rapidly rotating plasma nozzles cover a treatment width of up to 120 mm.
For effective surface treatment with atmospheric plasma systems, it is important to note the following: the treatment must always be carried out whilst the workpiece is in motion!
Atmospheric pressure plasma for surfaces
Atmospheric-pressure plasma is a technical plasma that is excited at normal ambient pressure. The process gas is usually purified, dry compressed air, although pure oxygen or nitrogen may also be used. Excitation is achieved via a high-voltage gas discharge. Due to the short mean free path of the particles at atmospheric pressure, the plasma is spatially confined.
With the rotating plasma RT nozzles from Diener electronic, it has been possible to extend the locally highly confined surface treatment to a treatment width of up to 120 mm.
Free from Volatile Organic Compounds
Plasma surface treatment is the key approach to VOC-free (Volatile Organic Compounds) manufacturing. It enables the functionalisation of components without the use of wet chemical processes such as solvents or primers. The environmentally harmful use of chemicals, rinse water and drying times is virtually eliminated, thereby conserving resources. Thanks to the process stability, the scrap rate can be reduced, thus also contributing to the principle of sustainability.
At a glance – the PC control system in the PlasmaBeam
Using the PC visualisation software running on Windows CE, the PlasmaBeam RT atmospheric pressure system from Diener electronic can be controlled intuitively via a 7-inch touchscreen. All process values are displayed, and limit values – such as gas flow, plasma current and temperature – can be adjusted. Graphical displays and the ability to export process data round off the PC control system. The unit features automatic process monitoring via built-in plasma current, gas pressure and gas flow controls.
On request, we offer a Profinet connection for the PlasmaBeam PC, PlasmaBeam DUO and PlasmaBeam RT models. This is the ideal way to integrate PlasmaBeam units into your in-line production and control them via the BUS system.
Remote connection – SUB-D connector
The PlasmaBeam RT atmospheric pressure plasma systems can be controlled via the remote connection. The external PC control unit for your production system can activate the plasma ON/OFF function and read the system status (‘Plasma ON / OFF / Ready’).
In the PlasmaBeam PC version, the remote control works in the same way as for the PlasmaBeam RT. However, it offers the added benefit of error message transmission.
For all versions of the PlasmaBeam with PC control, a Profinet connection is available on request. Please do get in touch with us. We at Diener electronic would be happy to advise you on the automation of surface treatment.
With Profinet connectivity on request
Seamlessly integrated into the BUS system of your in-line production line thanks to the Profinet connection. This enables the control system of your in-line production line to specifically control the PlasmaBeam PC from Diener electronic. The current process data is displayed and the system status is transmitted quickly. Your system integrator programmes the plasma torch ON/OFF function into the control system of the entire plant, thereby triggering the plasma.
On request, we offer the Profinet connection for the PlasmaBeam PC, DUO PC and RT models, as well as for many vacuum and low-pressure plasma systems.
Industry 4.0
Specialised equipment and systems from Diener electronic can be integrated into Industry 4.0 manufacturing. Together with our automation partners, we develop solutions for your specific in-line tasks, whether for atmospheric-pressure or low-pressure plasma.
The atmospheric-pressure plasma generator, for example, can be guided by robots and, thanks to selective treatment, achieves highly efficient operation.

FAQ Frequently Asked Questions
What is this special version of the PlasmaBeam RT designed for?
The PlasmaBeam RT from Diener electronic has been developed for processing wider surfaces at atmospheric pressure.
What are the main benefits of activation using atmospheric pressure plasma?
PlasmaBeam technology is suitable for in-line processes, e.g. plasma activation of continuous rubber profiles and hoses prior to printing, bonding, flocking or coating.
This technology is suitable for use with robots, i.e. the 2- or 3-dimensional surfaces can be scanned with the plasma beam using robots.
PlasmaBeam enables localised surface activation without the need for masking – the remaining surface areas are not affected.
What is the recommended distance between the nozzle and the surface when treating surfaces with the PlasmaBeam RT?
When using compressed air, the distance from the PlasmaBeam RT should not exceed 8 mm where possible. For greater distances, we recommend using nitrogen (N₂) as the process gas.
Does the PlasmaBeam RT produce any exhaust fumes?
Yes, in this PlasmaBeam RT, the plasma is generated using compressed air or nitrogen in an electrical discharge. This primarily releases nitrogen oxides (NO and NO₂). A smaller quantity of carbon-containing exhaust gases is, of course, also possible (CO₂, CO). The system must be equipped with an effective exhaust air system!
Which materials can be activated using the PlasmaBeam RT?
Virtually all solid materials, with the exception of thin polymer films and fluorinated polymers, can be electronically activated using Diener electronic’s PlasmaBeam RT.
Which gases are typically used in the PlasmaBeam RT?
Compressed air is the most cost-effective option. The PlasmaBeam RT system from Diener electronic can be used with pure nitrogen or even with forming gas (N₂/H₂) up to a maximum H₂ concentration of XX per cent.
Can the PlasmaBeam RT operate continuously, for example for 4–5 hours on the production line?
The PlasmaBeam RT system from Diener electronic is designed for continuous operation and often runs non-stop for several hours during production.
Are exhaust air filters necessary?
Yes, all systems must be connected to a proper exhaust system, regardless of the type of gas used! Nitrogen oxides, exhaust gases, fine oil mist (from oil pumps), etc. are produced, which must not be inhaled; furthermore, the gases are often acidic, meaning they promote the rusting of surrounding parts, machinery and equipment.
