Why Safety Features Matter in High-Speed Doors?
When it comes to high-speed spiral doors, speed is important — but safety is critical. Whether you’re operating in an automotive plant, food warehouse, or logistics hub, an unexpected door malfunction can cause serious injury or equipment damage.
That’s why NHentrance focuses not only on speed and insulation, but also on building a comprehensive, multi-layered safety protection system.
1. Photoelectric Safety Beam (Infrared Edge)
This is a must-have. When someone or something enters the door’s pathway, the infrared beam instantly detects the obstruction and stops the door from closing — preventing collisions and injuries.
✔ Wide-beam coverage
✔ Real-time reaction within milliseconds
✔ Ideal for pedestrian or forklift zones
2. Bottom Edge Pressure Sensor
Built into the bottom seal, this soft-touch sensor detects even small objects or slight pressure while the door is descending.
Once pressure is detected, the door will immediately stop and reverse, eliminating crushing risk. This is especially useful for:
- Busy warehouse doors
- Vehicle passageways
- Low-clearance docking areas
3. Emergency Release & Manual Override
In case of power failure, our doors can be:
- Manually released via interior chain
- Or opened with backup power (optional UPS)
This gives you peace of mind during blackouts, maintenance, or emergency evacuations.
4. Intelligent Controller with Fault Detection
Our smart control unit monitors every door cycle and:
- Detects motor/system failures
- Stores error logs
- Alerts operators of abnormal activity
Plus, all sensors and safety features can be managed from the same central interface, making troubleshooting quick and easy.
NHentrance Safety Commitment
At NHentrance, every door is equipped with:
- At least 2 physical protection systems
- Customizable sensor combinations (radar, loop, remote)
- CE-compliant control boards
We don’t just meet safety standards — we exceed them.
