ENULEC GmbH ELECTROSTATICStand number: A11
Company address: Rudolf-Diesel-Str. 7 22946 Trittau
Enulec offers custom designed solutions to electrostatic related problems. The product range includes highly effective and innovative ESA systems (standard top loading, maintenance free top loading, core charging and side loading systems) which have helped customers in the gravure printing industry to achieve high quality print standards along with high productivity and maximum standards of safety. In addition to this, EST electrostatic discharging systems assist customers in the printing and plastics processing industries to successfully eliminate static charges in machines such as winders, slitters and laminating machines, so ensuring smooth and safe production processes.
ENULEC Special ESA Top Loading
Gravure printing is characterized particularly by its outstanding quality of print which has been further improved by the Enulec ESA Top Loading system leading to the establishment of new standards. The main feature of the Special Top Loading system is a virtually maintenance- free, air assisted charge bar, previously unknown in the gravure packaging printing industry. Compared to the charge bars with open arrays of charging pins used in the past, this new and innovative technology offers the benefit that frequent cleaning is no longer necessary. This is achieved due to a special charge bar construction in which the charging pins are bedded completely into a small tube where they can not be contaminated by particles of ink or dust. Purged by slightly pressurised air a build up of dirt due to ink or substrate dust is prevented. In introducing this innovation, particular attention was paid to overcoming the various weaknesses associated with conventional ESA top loading systems with exposed charging needles, particularly as these relate to safety. Included among such weaknesses is the need for unwanted machine stops which are necessary due to the need for frequent and regular charge bar cleaning.
ENULEC ESA Direct Charging
The Innovation in ESA impression roller charging and gravure printing. Gravure printing is characterized particularly by its outstanding quality of print which has been further improved by the Enulec ESA Direct Charging – Side Loading system leading to the establishment of new standards. The maintenance free Direct Charging – Side Loading System, with its (German Gebrauchsmuster) registered design system of fluid transmission, enables best quality print results to be achieved in the gravure process whilst adhering to the highest safety standards. This technology is integrated into the products of worldwide leading machine manufacturers and is offered to gravure printers as a complete turnkey package. The distinctive feature of this fluid transmission system is the simplicity of its current transmission to the ESA style impression roller. Safe and fully controlled charging of the impression roller is ensured, even in the event of significant dirt contamination, and the system lends itself to the use of inexpensive impression rollers and sleeves.
New ENULEC ESA Roto Film PRO
With its capacity-free high voltage generator and higher-frequency voltage superposition, ESA ROTO Film – PRO counteracts the effect of charge buildup. This ensures constant ESA performance even under difficult printing conditions and with different film substrates. Capacity-free high voltage generation on the impression roller achieves the best print results and considerably reduces wastage and set-up times in a gravure press. This unique technology fully breaks up unwanted electric double layers and eliminates disruptive static charges. A further Enulec innovation is the optional »tachometric compensation « to automatically control ESA intensity dependent on web speed, independent of the operator. Overcharged impression rollers and operator faults are a thing of the past. Optimum ESA settings (FILM/PAPER) are guaranteed at any time.
ENULEC® In-Line Static Measurement
The ENULEC Inline Static Measurement System offers new possibilities for process optimization and an increase in safety during production. Substrates of all types are analysed for electrostatic charge in an inline process and the results so measured are recorded. When a pre-selectable warning threshold has been reached, the system provides a signal to the operator and provides information concerning the critical state of any static electrical charge which is present. The equipment further provides a signal contact to the machine control so offering optimum control over the production process.
ENULEC Discharge System
The ENULEC discharging systems are designed to meet highest safety requirements especially in a heavy contaminated environment. With this discharge bar manufactured from heat and shock resistant special glass-fibre reinforced material the pins are addressed to the substrate through a unique pin layout to ensure that the substrate is fully discharged. This feature enables more efficient discharge of the web and discharge at higher speeds. It was developed for applications where the web has a greater than normal tendency to retain charge, but it is of interest to all users who have particular static charge issues. Due to this special design no sparks can occur even if the discharge bar is contaminated with non conductive ink. The discharge bar is not only safer because the build-up of conductive bridges between the needles can not longer occur.
