Elsner Engineering Works, Inc. has introduced the Elsner Model EW-4-Series line of Shrink Film Roll Overwrappers. This new series of high speed overwrappers and heat shrink tunnels include a number of updated features. Highlights of this updated model include utilization of a new hot wire seal system, which has a micro-processor-based impulse controller. Features such as seal wire and pre-heat temperature and impulse time are now available from a new touch screen operator interface.
Other features include a mechanical drive system for the sealing head assembly in place of a pneumatic actuator to reduce air consumption. Also, new pre-shrink heaters are incorporated which use less energy. Elsner advertises its new Model EW-4-Series as more environmentally friendly.
