Cold Rooms and Freezers High-Speed Roll Up Doors

Industrial PVC Freezing Zipper Cold Room Door

The cold storage door has a simple design and is designed with a heating antifreeze device to ensure smooth and efficient operation of the product in a low temperature working environment. The structure incorporates the function design of collision avoidance recovery. When the door body is accidentally impacted, it deviates from the track and automatically repairs the return position during the ascent process. This structure not only facilitates the safe and smooth operation of the door body, but also operates more than 150,000 times a year without failure. It extends the life of the product while reducing component replacement and maintenance costs.

Such rapid door is specially designed for freezer, cold room, or cool room. It is made from 30 mm thick thermal insulated,sandwich curtain, and with all-round heating device to avoid frozen. Thus it can work well in low temperature like -25 º C. It can reduce thermal transmission by fast opening and closing, and thermal insulated door curtain. For each door, it can help customer save energy cost by at least USD 8000 every year,than traditional normal speed cold room sliding doors.

Heating devices are included on both sides of the column.The structural design of this product is characterized by trouble-free operation up to 150,000 times per year. It has the highest practicality and the lowest maintenance cost.

Product details:

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.

About the control system:

Using a dedicated (HOFIC) servo system, the core is a DSP chip, and the system receives incremental encoder signals and machinery at the rear of the motor.
The home position switch signal is used to set the door opening height:
--1 The system displays the fault code function through the LED tube;
--2 Steering protection: when the motor drive line is connected incorrectly, the controller reports an error directly, and the door does not move;
--3 The torsion ring, the position ring, the speed ring and the three rings are fully closed;
--4 Capable of braking function, without the electromagnetic brake pad, the motor can be stopped at the expected position, so that the door body stops at the limit position
