The jury of the Gravure AIMCAL Alliance Committee awarded an honorable mention in the category “Technical Innovation – Press” to German company Enulec for their new ESA Static Loop 360 system.
The system measures gravure web static on an ESA platform reading both web and nip static voltage. Protected by four patents, the web static control technology overcomes the unknown variable of nip static and reduces web static up to 70%. ESA Static Loop 360 neutralizes static via a patented safety grounding mechanism, which safely earths electrostatic charges that reach a 2kV threshold of nip static value.
The system learns static values during the print run, then automatically adjusts ESA power and polarity to the lowest achievable static level.
Reducing web static charges to the lowest level is paramount for every gravure printer with ignition reduction initiatives. Direct integration with the onboard PLC gives the press control of the ESA system. Described by the judges as an “awesome safety achievement,” the static reduction innovation provides true control of the process as well as cost savings.
