High speed Auto- Recovery zipper Door
Auto Recovery Rapid Door
Zippered Quick door Features
Open: 1.2-2.0m/Sec
High airtight energy efficient : Zipper patented technology and curtain rail technology combines high seal ability for maximum energy efficiency
Self-healing maintenance cost savings :When the door by the impact and dislocation occurs , repeat mosaic patented technology that is deralling repair system starts automatically , without any manual and automatic reset to its original state force to effectively reduce maintenance time saving cost
High security : Curtain soft and elastic , without any load at the bottom of the door to change , to ensure that the operator in an emergency state in the collision to the door when the operation will not cause harm
Push pull dual hinge system :unmatched safety record and absolute tightness in push pull twin shaft system, loading close dependence and the curtain at the bottom of the traditional fast door to achieve , you can drive dual axis system so that the upper curtain sprocket perfect bite does not depend on the door of its own weight can be achieved fast closing , this patented technology to avoid the hard parts usage of
More than one million times the durability performance : speed doors reduce the use of materials , easy to wear , strong and flexible curtain is very durable , can withstand million of opening and closing operation ,
in the use of some products has reached 500 million times for opening and closing
The soft curtain anti-collision fast door has simple structure design, which is beneficial to stable operation, reduces the frequency of repairing and replacing wearing parts, effectively improves the durability and service life of the equipment, and the curtain can be derailed in the event of an accidental impact, and during the ascent Automatic reset, no need to manually repair and reset the whole process.
