COROTEC TO INTRODUCE NEW UNI-DYNE® FEATURE THAT ALLOWS FOR FAST, EASY ELECTRODE CLEANING AND JOB CHANGEOVER AT LABELEXPO AMERICAS 2002
New Removable Electrode Cartridge Feature Offers Unprecedented Ease Of Use

Farmington, CT (September 10, 2002) Corotec Corporation will be featuring their Uni-Dyne® concept corona treating system with its new removable electrode cartridge designed specifically for narrow-web converters at Labelexpo Americas 2002 in Chicago (Rosemont), September 10-12, booth # 3805. The new feature allows for fast and simple removal, cleaning, and replacement of the electrode assemblies, significantly minimizing maintenance and downtime.

In addition to seeing this new system at Corotec's booth, show visitors can see the system installed and operating on a Comco press in the Mark Andy/Comco booth #319. Corotec Uni-Dyne corona treating systems will also be in operation at Labelexpo on Mark Andy (Booth # 319) and Nilpeter (Booth # 3105) presses. Additional products featured at Labelexpo in Corotec's booth include the Corotec Plasma-Jet® 3-D treating system with NEW microprocessor-based alarm system, and the Nozone® ozone destruction system.

Narrow-web processors looking for simplicity can visit Corotec's booth to see the Uni-Dyne system in action. It is the first narrow-web corona treating system to incorporate a fully integrated high performance power supply, treating station, and power density control into a single, compact, self-contained unit. Clean, simple, and efficient installation translates into significant cost savings from day one. Customers need only to remove the machine from the box, connect their ozone exhaust and incoming power, and begin operation.

The latest feature of Corotec's Uni-Dyne® narrow web treater, the removable electrode cartridge with a pull out handle, allows the entire electrode assembly to be removed in seconds for cleaning. The open design of the cartridge itself allows excellent access for thorough cleaning. Customers can keep spare cartridges on hand and even have different electrode configurations for different treating applications if desired. This feature dramatically reduces downtime - when the cartridge in the treater needs cleaning, it is out with the old and in with the new.

Easier to clean electrodes and replacement cartridges provide unprecedented simplicity for customers and are especially advantageous to those operating in excessively humid environments where electrode maintenance is more frequent. Corotec's new electrode cartridge design is available in fixed-width conventional or bare-roll configurations. It is also available as a retrofit for most existing Uni-Dyne® and component-based narrow-web systems.

An added bonus to the new Uni-Dyne® electrode cartridge design is that it allows for better cooling of the electrodes. Because more power can be applied into the same amount of space, a higher power density can be achieved, and this translates to higher line speeds.

Corotec is also exhibiting the Plasma-Jet® corona treatment system with a new microprocessor-based alarm system. The Plasma-Jet® alarm system allows users to continuously monitor their product treatment application to ensure consistent operation within specified parameters, while treating products by using an electrical discharge (corona) to selectively increase the wettability of 3-D parts prior to the application of labels, nomenclature or graphics. Multiple surfaces and difficult geometries can be treated with the Plasma-Jet® with both consistency, and superior one-pass coverage.

The NEW Plasma-Jet® alarm system is designed to continuously monitor the critical operating parameters of each Plasma-Jet® discharge head and provide an independent alarm for any head that falls outside of the parameters for normal operation. The alarm is available as an option on all new Plasma-Jet systems and can be easily retrofitted into any of Corotec's older PJ-X Series models.

Corotec's Nozone® system clears the air simply and efficiently with negative pressure flow thereby solving the problem of ozone leaks at poor connections. It features an all-aluminum, upright canister design that employs a true catalytic reaction to destroy ozone molecules without degrading or depleting the catalyst. The Nozone® system requires only a single off the shelf blower at the outlet side, unlike positive pressure units.

Corotec designs and manufactures a complete line of standard and custom corona discharge surface treating equipment of narrow web and wide web applications, systems for controlled atmosphere testing, ozone generators for coating and laminating processes, and other advanced applications.
