The Nimbus is a dual nozzle atmospheric plasma treatment system ideally suited to surface activation, cleaning and modification of a wide range of materials including polymers, metals, glass and ceramics.

The Nimbus is extremely simple to operate via the front panel soft-keypad and can also be interfaced with external control equipment using the rear panel Sub-D connector providing a variety of I/O control inputs and status read-back to ensure seamless operation with automation lines or robot cells.

The Nimbus operates from a standard single-phase electrical outlet and require only compressed air for operation.

The compact controller features an interlocked airflow regulation unit as standard so that no ancillary equipment is required.

Atmospheric Plasma Advantages

Atmospheric plasma systems address a range of specific treatments & material treatments including; plasma cleaning, plasma surface activation to improve adhesion, PEEK & other engineering polymers, PCBs, metals, ceramics and glass.

  • Compact benchtop or rack-mount unit
  • User-friendly soft-key interface
  • I/O subsystem for line integration
  • Integrated gas monitoring & control
  • Precise & repeatable
  • Treatment of polymers, glass, ceramics, metals
  • Fast, localised atmospheric plasma pre-treatment of parts prior to bonding
  • Ultra-fine atmospheric plasma cleaning
  • Surface activation with atmospheric plasma
  • Highest quality treatments
  • Localised treatments
  • Very low operation cost & easy integration with automated lines

Easy operation

The compact control unit can be operated manually or interfaced with existing control equipment. Plasma start and stop signals are supplied via a rear panel Sub-D connector. All important parameters are available on the same connector for read-back and monitoring.

Typical Process Results

Images show increased wettability on metal and polymer samples following plasma treatment.

Atmospheric Plasma Applicators

The Nimbus has dual plasma heads operating from the same single controller and doesn’t require any additional bulky transformers. This can be useful for treating multiple areas, larger areas or in place of multiple line passes.

Our proprietary, high stability plasma power generator allows for high line speeds when operated as part of a continuous processing facility.

The functionality of the Cirrus and Nimbus has been extended by the introduction of two new application-specific nozzle attachments. These are user-replaceable and can be supplied with a new system order or for retro-fitting to an existing system.


The ‘Mode’ nozzle is standard and suits 95% of all plasma pre-treatment applications


Our ‘Finite’ nozzle is best suited to confined areas or where a longer reach is needed, for example when treating channels or spaces between components.


The Nimbus produces dual 10-12mm diameter jets of reactive plasma species which are highly efficient at removing hydrocarbon surface contamination and rendering a surface hydrophilic and suitable for subsequent processing, e.g. bonding, printing etc.

Repeatable and Reliable

The Nimbus system only needs a compressed air supply for operation. Plasma parameters and gas delivery are continuously monitored and controlled to deliver the same result irrespective of changes in gas delivery characteristics. The unit features a number of electrical and compressed air safety interlocks that ensure long term, trouble-free operation.

Robot Motion Automated System

The atmospheric systems can be supplied integrated with a 3-axis robot with up to 500mm by 500mm working area and 150mm of Z-axis movement. Includes stop/start box and teach pendant. manuals on CD, mains lead, I/O cable between robot and plasma unit.

Enclosure optional/cart-mounted:

The robot is available in either desktop or cart-mounted versions with optional guard frame and safety light curtain interlock.

  • 200mm to 500mm XY travel options
  • 255 stored programs
  • Up to 30,000 data points
  • 16 I/O channels
  • Safety light curtain protection
  • Bench or cart-mounted
