MODEL
E9700
UNITYER®
The model E700 Unityer comprises a removable all-electric Tying Unit and a hydraulically operated stationary Compacting Station. All tying functions are AC gear motor driven using AC Vector Drive technology. The E9700 Tying Unit includes automatic waste wire coiling for disposal, a high capacity accumulator and automatic threading after a coil change. The Compacting Station provides side and top compacting functions powered by a small on-board HPU.
Features and Benefits
