Description
Nimbus
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. | |

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.

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