High Speed Rolling Door Mir Flex Auto Tracking

A rolling door for medium size openings, ideal for separating different environments and passage ways between buildings, warehouses or stores. Designed with different small size profiles, they take up little of the opening s light space and require little space on the side bracelets and on the lintel. They are resistant to moderate air currents and the curtain has a system of flexible reinforcements that come off the guides when they receive a strong impact and roll up again when the door opens.

Structure
Vertical mountings made up of a reinforced guide made from extruded aluminium and with a specific design for this model door, housed in a double rectangle profile made from 1.5 mm Stainless Steel.
Galvanised and lacquered. Galvanised and lacquered steel sheet base with eyelets for fastening to the floor. Black polyethylene tracking. Support platform for the rolling drum and the motor made from galvanised and lacquered stainless steel. Aluminium rolling drum with galvanised steel shaft on supports with ball bearings.
The bases are fastened to the floor and the head to a light structure that prevents swaying. In order to ensure greater resistance to frontal forces, one or two middle fastenings are required depending on the height.

Canvas specifications
The canvas has a series of lengthwise reinforcements, which provide rigidity and the resistance required for the air pressure currents it will endure. A concave/convex profile made of composite materials is sheathed in the curtain.
This profile has extraordinary resistance to breaking (even with violent impacts from moving vehicles) and can withstand significant flexing without causing permanent deformations. The lower skirting is a PVC bag, enabling perfect adjustment even on uneven surfaces. The bag is painted in yellow and black Stripes, for greater identification of the transit area.

Auto tracking system
In the event of impact on the curtain, the sheet bends thanks to the flexibility of the reinforcements and can come off the guides. When it goes up again, the ends of the reinforcements are reinserted into the guides thanks to the auto tracking system on the lower part. The door is then ready for the next manoeuvre. The system reduces the span width by 80 mm.

Motor and control panel
Self-locking reducer motor for intensive use with integrated position mechanical Switches.
Electro-brake for exact positioning and locking the canvas. Manual release of the electro-brake with a handle. Manual opening system with a crank.
Control panel: 220 V Single phase power supply and 24 V operating voltage.
Control panel with programmable automaton and frequency converter for speed regulation.

Access security
Option 1: Wireless contact band on the main edge and infra-red barrier at 500 mm from the floor.
Option 2: Infra-red curtain up to 2.5 m height.
This system has a series of photocells fitted one on top of another that create the infra-red barrier on the entire height of the door and up to 2.5 m high, which detects any object, including small objects, preventing lowering the door or raising it again if it has already begun to lower. Avoids physical contact with the door.

Options
Emergency opening system via UPS or mechanical system.
AISI 304L and 316L stainless steel structure.
ATEX certified doors for explosive environments.
Powder, paint or gas.
