Achieve strictly defined distances between the conveyed unit loads with ZPA (Zero Pressure Accumulation). Thanks to a controlled material flow you can thus prevent unintentional collisions and save energy at the same time. This is because the motors only run when conveyed goods are actually being transported in the system.
Our pre-programmed ZPA solution allows you to implement zero pressure accumulation easily and cost-effectively. It is compatible with all Bihl+Wiedemann ASi drive solutions – and thus with drive systems from a wide range of manufacturers (e.g. INTERROLL, RULMECA, Itoh Denki, SEW EURODRIVE, NORD DRIVESYSTEMS, Rockwell Automation, Lenze, Bonfiglioli).
ZPA with simplest connection technology for frequency inverters (top) or up to four motorized rollers (bottom).
