Pbj industrial electronics manufactures corona treaters for multiplayer blown films. These corona treaters are very operator friendly and facilitate easy threading and the two pneumatic cylinders are useful for pneumatic opening of the assembly, thus reducing the downtime of the machine. The air gap adjustment can be done by turning screws without hampering the electrode to roller parallelism depending upon the thickness of the substrate. Top grade dielectric sleeves with designs assuring top quality highest concentricity and dielectric strength for better treatment performance. Some of the salient features of these corona treaters include fin type segmented metal electrodes with special coating "corronil" to avoid corrosion; and corrosion-proof cross members with high standard of workmanship thereby ensuring low maintenance costs and higher working life. These corona treaters are available with operator safety features like electrodes ensured in proper position with a safety limit switch before the operation of corona treaters. If there is any lump in the films the electrode head retracts and an audiovisual signal is initiated, and the corona treater trips instantly thereby preventing damage to the substrate during operation. Under any circumstances the treater roller is at stand still. The company supplies these corona treaters rollers provided with grounding brushes to prevent premature bearing failure. Auto watt density control corona generators are incorporated with latest generation igbt technology and higher efficiency of corona treatment can be achieved at higher frequencies. The unique feature of auto watt density control of this corona treaters for multiplayer blown films ensure consistency in treatment levels proportional to the line speed. These machines are available with a critical feature of no effect on the corona treatment by the variation in electrode gap or thickness of the substrate and supply voltage have. These corona treaters have an easy maintenance with easy plug in cards that enable efficient servicing at all times. The company provides an easy plug socket connectors for high voltage supply from transformer to the assembly.
