Factory Direct Supply Storage Freezer Rapid Ambient Cold Room Roller Shutter Door

door width 1000mm - 4000mm, door height 1500mm - 4000mm

A special servo system is used with a DSP chip as the core. The system sets the opening height of the door by receiving the
incremental encoder signal at the end of the motor and the mechanical home position switching signal in conjunction.
1.System for displaying fault code functions via LEDs.
2.Steering protection: The controller directly reports an error when the motor drive line is connected incorrectly and the door
does not move.
3.Torque ring, position ring and velocity ring are all closed
4.The energy vector brake function stops the motor in the desired position without the use of electromagnetic brake pads, allowing
the door to stop in the limit position without any deviation

The motor drive system adopts servo motor system: encoder; brake system; reducer; emergency manual opening mechanism.
1.Constant torque output from servo motors for optimum functioning of safety guards (e.g. infra-red, etc.) and rapid rebound.
2.Strong overload capacity, can work more than 1000 times a day in some high frequency occasions

Opening speed 0.6-1.2m/s (adjustable), closing speed 0.6m/s (adjustable)

The whole door curtain is made of double-layer PVC insulation foam, the thickness is 10MM

the track is made of aluminium alloy, 2.0MM thick; the frame of the balcony is made of 304 stainless steel

The structural design and application of the top seal and bottom seal of the door body can effectively isolate the air pressure
convection on both sides of the door body, further strengthening the airtight performance

The curtain guiding parts, curtains and rails in the door running guidance system are closely coordinated, and the materials have
strong wear resistance to ensure the overall wind resistance, which can resist wind at the national standard level 6

1. Infrared safety protection: Both sides of the door frame are equipped with a pair of electric eyes, fast door below the object,
so that the door keeps opens; when the door body descends below the object through, the door will open to the most open position,
to wait for the following no obstacle and then delay the descent.
2.Bottom safety protection edge: when the door body is descending, as the object is in the blind area of infrared safety
protection, the door body presses on the obstacle below, the door body will quickly rebound at the maximum opening, effectively
protecting the object below or pedestrian to avoid accidents (standard configuration)

In the event of a power failure, the motor brake can be turned on at any time and the door can be held up with the aid of a
balancing system, which can effectively solve the problem of the door not opening due to a power failure or malfunction.
