Elero: Rolling Door Drives
From a small rolling door in a shutter system to a heavy commercial grille, elero covers the span: the VariEco M NHK handles compact doors with its built-in emergency crank, and the Type 15 W is the workhorse for heavy roller shutters, doors and grilles at 120 to 300 Nm. elero has these drives certified regularly by independent examiners, and the NMA versions add emergency manual operation so the door opens even when the power fails.
Topp: Door Automation - Swing Door Operators
