Q1: What is the difference between a zipper high speed door and a normal PVC high speed door?
A: A zipper high speed door uses a zipper-style side guide system instead of traditional guide rails. This design provides better sealing performance and allows the curtain to return into the guide after accidental impact, helping reduce downtime and maintenance.
Q2: How does the self-repairing function work?
A: When the curtain is hit and comes out of the side guide, the zipper structure can guide the curtain back into the track during the next opening cycle. This helps the door recover quickly without complicated manual repair.
Q3: Is the zipper high speed door suitable for cleanrooms or laboratories?
A: Yes. The zipper side guide provides better sealing against dust, air leakage and insects, making it suitable for cleanrooms, laboratories, food processing areas, pharmaceutical workshops and other controlled environments.
Q4: Can it be used in cold rooms or temperature-controlled areas?
A: Yes. The fast opening speed and tight side sealing help reduce air exchange and temperature loss. Please share the room temperature, door size and traffic frequency so we can recommend the suitable curtain and motor configuration.
Q5: What happens if a forklift accidentally hits the curtain?
A: The flexible PVC curtain and zipper guide system are designed to reduce damage from accidental impact. In many cases, the curtain can reset into the guide during operation, helping reduce repair time and daily maintenance cost.
Q6: What safety devices can be added?
A: Common safety options include photoelectric sensor, radar sensor, bottom safety edge, emergency stop button, warning light and manual release system. These devices help protect people, vehicles and goods during daily operation.
Q7: What control methods are available?
A: The door can be operated by push button, remote control, radar sensor, vehicle loop detector, pull switch or access control system. We can recommend the best opening method based on your traffic flow.
Q8: What information do you need for a quotation?
A: Please send the door opening width and height, application area, indoor or outdoor use, temperature condition, daily opening frequency, required voltage, curtain color and quantity. We will recommend the suitable configuration and provide a quotation.
