Narrow Web

Corotec extends the advantages of full-size corona treating systems to the narrow web industry, with modular, bolt-on units for simple in-line installation on every pres.

Our NEW Uni-Dyne® narrow-web system offers unprecedented ease of installation and use. Never before has it been so easy to install a corona treating system on a narrow-web press, since the Uni-Dyne system comes with virtually everything already done for you – all you do is bolt it in place and add power! The Uni-Dyne system can also be supplied with our Power Density Control system already installed for you, right in the power supply module. With the innovative Uni-Dyne system, you get all the most desired features and options in a single, compact, easy-to-install package.

Our compact narrow-web treaters offer the operational and performance features of large systems, including stepless output power control, output metering, operating status lights, and interlock terminals. Also, the high-voltage transformer on some models does not require tap changes for load matching and can be located directly on the treating station end plate, eliminating the need for special high-voltage wire runs.
