Powerful results from simple-to-install components
We specialize in high-throughput systems for in-line production processes. As such, we have engineered our systems to the most exacting tolerances so they are exceedingly reliable. We are able to integrate our technology into a diversity of production situations. The simplest installations consist of single small jets, for say, the manual treatment of sensitive electronics. More complex installations are for high-speed web applications that are 40 inches wide and operate at 1200 feet per minute. In other cases we integrate our technologies with multi-step, fabrication processes that use high speed robotic cell systems.

While the benefits of the technology are many, including increased throughput, lower material costs, improved quality, greater reliability, improved safety and the near-complete elimination of solvent emissions. Surprisingly perhaps, this is accomplished with only three components:

1) The generator
2) The high voltage transformer
3) The plasma jet

The generator
The generator converts the incoming electrical signal into a stepped high-frequency pulsed current. It also provides various control functions that may include limit switches, door locks, emergency stop modules, compressed air and process monitoring.

There are options for touch screen digital control of plasma process parameters, online maintenance recommendations and full data collection.

Our more recent plasma generators use state-of-the-art insulated gate bipolar transistors (IGBT) that control high currents with very low control power. Our latest generation generators are based on a patented impulse discharge double resonance system with pulse-pause modulation.

The high voltage transformer
The electric current from the generator then passes through a transformer that steps up the voltage. The transformer needs to be situated within 7 feet of the jets.

We have a range of generators/transformer combinations that deliver power from 1,000 VA through to 5,000 VA.

The plasma jet
The jet is comprised of three components, the nozzle, the chamber and the mounting system. The chamber contains the electrodes where the compressed air is combined with the high-frequency discharge to form the stream of plasma. The plasma beam is then directed at the material to be treated through a nozzle.

The nozzle
The nozzle is carefully engineered to give the precise dimensions and velocity of plasma required at the optimal angle. Single nozzles produce a straight plasma stream and are suited for the treatment of narrow profiles. For wider areas of treatment the chamber and nozzle are rotated at high speeds. For even larger work areas an unlimited number of jets can be mounted next to each other.

	We have over 300 custom nozzles available each customized for different applications.

What do I need to operate a plasma system?
All you need are a power supply of any of the following voltages: 120V, 240V, 400V, 480V or 600V. Small units require 120V. For larger installations a tri-phase supply of 480V is ideal. Plus you need clean compressed air (60 psi or more), which, if not already installed, can be added with a low cost ancillary unit.

Do I need to install special venting?
Openair^® plasma systems do not produce pollutants. No ozone is produced and concentrations of nitrous oxides are produced at the lower limits of measurement. Venting is recommended but for some applications it is not essential.

Do I need specialty gases?
No, the systems usually run on clean dry compressed air. However, for special applications, other gases may be employed to create special functionalities. Sometimes pure nitrogen, CO 2 or additive gases are employed. Please ask if you have an unusual application.

How much does it cost to run an Openair^® plasma system?
Running costs are extremely low, especially when compared to the price of most other methods of surface treatment. The cost per jet is of the order of 10¢ to 20¢ per hour. For high volume applications, the low running costs and increases in productivity often mean that the capital cost pays back astonishingly quickly. We can provide estimates of running costs, including energy and maintenance.

What is the cost of an Openair^® plasma system?
A lab system for evaluation purposes starts at USD$30,000. Full industrial systems, depending on the application, level of integration and treatment width, usually range between $50,000 and $500,000.

Are there cheaper plasma systems?
Openair^® plasma is a patented technology that is only available from Plasmatreat. It is possible to buy corona and flame systems that cost less but their functionality is not comparable and the running costs are higher. We deliver extraordinary value because of the experience our team of technicians and engineers brings and from our track record of installing high throughput systems around the world and our extensive knowledge of adhesives, coatings, instrumentation and applications technology.
