Product Description

 

Product Description

Set fast, energy-saving, sealed, wind-resistant, environmentally friendly in one of the new metal industrial doors, has a high degree of reliability and practicality, its operating speed is more than 6 times that of the industrial sliding door, by virtue of the efficiency of the work, the high speed spiral door is gradually replacing the industrial sliding door.
The door plate is produced by a large-scale assembly line with French technology, filled with polyurethane industrial heat preservation material inside the door plate, and the bridge-breaking design can isolate the indoor and outdoor temperature loss, which can effectively save energy. The two ends are connected by hinges, and the door panels are connected by double side sealing strips, which ensures the sealing and also effectively fights against the strong convection wind pressure.
Turbo high speed spiral door can prevent the intrusion of outsiders and at the same time can withstand weather changes, can isolate the indoor and outdoor air convection, is used in frequent access, and is the ideal choice for industrial energy saving and reduced consumption.
 

Product Parameters

 

Speed	Up to 2.5m/s (98.43 inches/second) with servo drive. Maximum speed depends on door size.
Size	Minimum: 1000mm(3.28'DOW) x 1000mm(3.28'DOH)  Maximum: 8000mm(26.25' DOW) X 9000mm(29.53'DOH)
Panel Material	0.7mm(0.028") thick is for aluminum plate foaming density is 45kg/m3(2.8lb/ft3) thickness is 43mm(1.69") and 80mm(3.15") the height is 220mm(8.66") for single panel color: white(RAL9016); silver(RAL9006); grey(RAL7045); aluminum original color
Drive System	Using three kinds of servo-motor: 0.75KW, 1.5KW and 2.2KW. This depends on the door size.  Each motor assembly is with gearbox and brake. Servo-drive control the running of motor. motor drive the panel through the transmission chain and drive shaft and lift chain. The tension spring will counterbalance the weight of panel.
Electrical Requirements	standard: 220V/1PH/50/60Hz(servo-motor) oversize door: 380V/3PH/50/60Hz door sizes greater than 36m² (for 36mm thick panels) and 30m² (for 80mm thick panels)
Vision Options	The material is transparent PC with a thickness of 2mm. For 80mm thick panels the dimensions are 422mm (16.61 inches wide) x 168mm (6.61 inches high) For 43mm thick panels the dimensions are panel width through, 140mm high
