freezer door001

Shenzhen Hongfa fast door production of the new cold storage zipper doors to achieve a different way to open the door and protection devices to achieve the position, speed and torque of the full closed-loop servo control. Avoid the cold storage high speed door in the movement of the cumulative and interference error, the door body long-term operation does not run out of position. Electromagnetic compatibility design, to avoid complex wiring electromagnetic interference and plug-induced failure. Motor Z high speed 2000 rpm, the speed of high speed freezer doors can Z high running speed 2.0 meters/second. Flexible quick start - high speed operation - flexible slow stop, S-type speed curve infinitely speed regulation. Constant torque intelligent follower system, the output torque follows the load change of door operation, smooth operation. Through as many as one hundred control parameters, engineers can adjust each door to normal state. The system of the new industrial freezer doors has the function of memorizing multiple sets of state parameters and can restore the memorized parameters with one key at the time of failure, while the system adopts SEJ motor, which has the advantages of high efficiency, energy-saving, low temperature rise and high torque.The cold storage high speed door is a kind of zipper high speed door , the main difference between it and the ordinary zipper high speed dooris the door curtain
