Recovery Type

Product Features

Premium automatic door to save maintenance & repair cost
through automatic recovery from external impact

  • This door is mainly installed in a site where it is highly likely to crash into an automatic door often
    because of much movement of vehicles like forklift or distribution.
  • After collision, this premium door makes it possible for automatic recovery mechanism to perform
    automatic recovery with no extra repair cost.
  • This zipper type door has strong sealing power. Therefore, it remains closed strongly.
  • This door is particularly good for electronic and automobile industries.

PVC Guide driving principle

The direct sprocket type is adopted so that the axis of driving
door curtain is separated from the axis of collecting the curtain.
Therefore, it is possible to make the system stable and minimize
damage of the door sheet. This door is designed with the special
synthetic PVC to support the door curtain on both sides and with
extruded rail to prevent guide deformation and damage at vehicle
collision. Since there is no gap of tooth and guide, it is possible
to minimize the inflow of impurities and external air.
icon Sheet

The world-class premium fabric (SOL Screen Coating ) for boat

  • No twist and pinhole of fabric; excellent adhesion strength for easy process
  • Surface treatment: Fluorine (PVDF), acrylic, and PU treatment; single-side & double-side repeated 1-5 times of treatment
  • Customized selection (antibacterial & flame-resisting dual weaving structure)
icon Motor
  • 1. Vertical axis reducer with high efficiency

    About 20% efficiency higher than worm gear; more than 85% efficiency of reducer
  • 2. Low noise & low vibration

    Lower noise and vibration than bevel reducer/average 52~65dB
  • 3. High strength and long lifespan

    Increased gear strength and lifespan through carburizing heat treatment
  • 4. Lightweight and optimization

    Installation space saving and case and reducer weight reduction by offset

icon Sensor

1. Ultrasonic sensor

Herkules 2E

Herkules 2E
Herkules 2E


  • Detect and distinguish between people or vehicles
  • For heights of 2 to 7 m
  • Temperature range –30 °C to +60 °C
  • Direction recognition and cross traffic masking
  • Individually adjustable detection area provides for an enormously wide range of applications
  • Mask out crossing traffic, which prevents unnecessary opening and lowers energy consumption

PrimeMotion C

PrimeMotion B&C
PrimeMotion B&C


  • Based on microwave technology
  • Up to 4.8 metre wide field can be used, Mounting height up to 4 metres
  • Its cross traffic masking and direction recognition functions avoid unnecessarily long opening times and save energy.
  • User-friendly operation make it easy to install and mean it is ready to use quickly.

2. Vehicle & Loop Detector

Matrix (Loop Detector)



  • Detect vehicles, forklifts, carts and metal objects
  • Laying loop detector and its connected coil on the ground
  • Accurate detection control and stability
  • Enable to prevent all types of interference by controlling four frequencies

3. Safety Sensor

Safety Sensor (Basic Option)



  • Patent obtainment
  • Attachment of safety cap for malfunction prevention and normal operation even with impurities
  • Minimal non-detection area by basically providing 4-point safety sensors on the left and right frames (two in each frame)

Pressure Sensor



  • At door down, if an obstacle increasingly presses the tube, door stops or is opened.
  • Automatic door opening when an object touches door
  • Even low pressure of 3 to 4 mbar is enough to guarantee the electric contact will switch
  • high level of response sensitivity, which enables it to protect people and vehicles from practically all directions.
