door, it can help customer save energy cost by at least USD 8000 every year,than traditional normal speed cold room
sliding doors.

Features:
1. High speed opening and closing
The running speed can reach 2m/s, 10 times as traditional roller shutter door. This obviously improves passing effici-
ency through it and enhances overall output.
2. High frequency operation
The operation frequency can reach more than 1000 times per day without any faults. This meets need of heavy tra-
ffic in some areas.
3. Good thermal-insulation
Double skin is 0.8mm PVC fabric, and inside is filled with high-density insulating rock wool . Total Thickness of door
panel : 20-40mm; With excellent thermal insulation performance. It can prevent thermal loss of the cold room and sa-
ve energy
4. It can work in extreme low temperature.
There is heating device around the door to avoid freezing when door running. 
5. Excellent safety performance 
Dual protection design. Every door is equipped with safety photo sensor and proximity sensor, avoiding collision acci-
dents and protecting passing human or vehicles.
