The aluminium roller door Alumir PS from Angel Mir is intended for a semi-intensive use in passages having a lot of traffic, such as buildings with community garages or car parks.
Depending on the size of the door, the motors can withstand 30 to 40 manoeuvres per hour. It has a quick motorization with frequency variator that prevents blows because of abrupt braking, and allows to adjust the speeds to customer requirement. With this system, the gear motor performance is improved and protected, achieving therefore a better reliability. The motors can carry a drum cover receptacle, although it is compulsory for doors lower than 2500 mm height.
The guides of the door are provided with PVC guiding profiles to improve sliding and die down noises. On the other hand, the aluminium blades can be perforated or die-cut, and can be lacquered in different RAL colours (aluminium std, anodized silver, white 9016), or optionally anodized.
It is a silent roller door with anti-entrapment safety system through a photocell curtain that protects the whole width of the door.
