4 × Plasma = QUATTRO
The QUATTRO plasma nozzle offers advantages for the treatment of wide surfaces. With its four individually arranged nozzles, this atmospheric pressure plasma head enables a treatment width of up to 32 mm.
The PlasmaBeam QUATTRO from Diener electronic is used for: degreasing / cleaning, hydrophilisation and pre-treatment prior to: printing, bonding, painting, soldering, coating, potting, adhesive bonding and laminating. It is used in many industrial sectors, such as plastics technology, the automotive industry, solar cell and battery manufacturing, electrical engineering, elastomer technology, the furniture industry, packaging technology, as well as medical technology and optics.
Cleaning
The Atmospheric pressure plasma system PlasmaBeam QUATTRO offers a wide range of applications for the local ultra-fine cleaning of polymers, metals, ceramics and glass. This process breaks down molecular residues of contamination.

Activation
Atmospheric pressure plasma is a highly efficient process for locally improving the adhesion of various substrates prior to painting, gluing, printing or bonding. Plasma activation using the Atmospheric pressure plasma PlasmaBeam QUATTRO system creates polar bonding partners and increases the surface energy.
QUATTRO – four plasma nozzles in one plasma generator
The principle of the atmospheric plasma system PlasmaBeam QUATTRO comprises the basic components: the power supply unit and the 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 emitted via the four plasma nozzles of the PlasmaBeam QUATTRO.
Thanks to its staggered plasma nozzles and a weight of just 1 kg, the PlasmaBeam QUATTRO from Diener electronic achieves a remarkable treatment width of up to 32 mm. Ideal for a wide bonding groove to ensure a stronger hold.
For effective surface treatment with atmospheric plasma systems, the following is important: the treatment should always be carried out whilst the workpiece is in motion!
Securing the plasma generator
As either the workpiece being processed or the plasma generator is in motion, the plasma generator must be permanently installed. On request, Diener electronic supplies task-specific mountings for the PlasmaBeam QUATTRO to ensure the plasma generator is securely fixed in place.
Targeted, partial surface activation using PlasmaBeam
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 are also possible. 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.
Consequently, the atmospheric pressure plasma in the PlasmaBeam QUATTRO by Diener electronic is always partial, enabling targeted activation of the surface exactly where it is required.
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 sustainability.
Manual / Semi-automatic control
In manual mode, the PlasmaBeam QUATTRO atmospheric pressure system from Diener electronic is controlled via controls on the front panel. In semi-automatic mode, it is controlled via a SUB-D connector on the rear panel. Automatic process monitoring is provided by the plasma current, gas pressure and gas flow controls (depending on the PlasmaBeam QUATTRO) built into the unit.
Remote connection – SUB-D connector
The Atmosphärendruck plasma systems PlasmaBeam QUATTRO 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 QUATTRO. 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.
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 QUATTRO designed for?
The PlasmaBeam QUATTRO 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 QUATTRO?
When using compressed air, the distance from the PlasmaBeam QUATTRO should not exceed 8 mm where possible. For greater distances, we recommend using nitrogen (N₂) as the process gas.
Does the PlasmaBeam QUATTRO produce any exhaust fumes?
Yes, in this PlasmaBeam QUATTRO, 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 QUATTRO?
Virtually all solid materials, with the exception of thin polymer films and fluorinated polymers, can be electronically activated using Diener electronic’s PlasmaBeam QUATTRO.
Which gases are typically used in the PlasmaBeam QUATTRO?
Compressed air is the most cost-effective option. The PlasmaBeam QUATTRO 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 QUATTRO operate continuously, for example for 4–5 hours on the production line?
The PlasmaBeam QUATTRO 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.
