Plasma-Jet surface treatment system by Corotec Corp, Farmington, CT, features a head design 50% smaller than standard heads. The systems are used to ensure bonding of inks, adhesives, and coatings on a range of products including medical devices and electrical and electronic components. The smaller head enables installation and operation in space-restricted applications. The system’s blower and filter assembly are away from the discharge head and located inside the main cabinet. This saves space and reduces the need for periodic maintenance and cleaning of the filter assembly. The discharge heads come in plastic or ceramic. Ceramic heads are typically used in the harsh and dirty environments.
