The different models have different configurations, but all of them have the option of either a convex or concave door (with the operator on the inside or outside respectively), a monitored closed loop electronic control panel, and panic batteries with a 30-minute charge for use during power cuts.
Both the C50 circular model, which is the ideal fire barrier solution, and the curved or semi-circular versions of the C25 model are specially designed for accesses to trade fair areas, theatres, banks, offices and other public buildings where the functionality of a sliding door can be combined with a stylish design similar to that of a revolving door.
