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:
| Technical classification | Technical Parameters |
| Heating antifreeze device | The design and application of the heating mechanism avoids the freezing of the guide rail caused by the heat exchange caused by the frequent operation of the door body, further ensuring stable operation and working efficiency of the door body in a low temperature environment. At the same time, it is possible to install and remove the box equipment according to the needs, and doublely guarantee the working performance of the product in a low temperature environment. |
| Collision recovery structure | In the event of an accidental impact, the curtain can be derailed and automatically reset during the ascent, without manual repair and control unit resetting. |
| Opening speed | Opening speed 0.6-2.5M/S, and can be set |
| Closing speed | Closing speed 0.6-1.2m/S, and can be set |
| Curtain | High-strength environmentally-friendly polyester fiber material is added with tear-resistant fabric in the middle. The overall thickness of blue and full-soft curtain is not less than 1mm. The tensile strength is high and the wear resistance is good. There is no friction between the curtains to generate static electricity to attract dust. Fill the insulation material. Applicable temperature: -30~+70°C. |
| track | The track is made of stainless steel and galvanized paint, and the surface is spray-coated to prevent rust. |
| Door component insulation protection | The Control Box and other components must meet IP54 and above, and meet the national electrical safety standards, even in harsh environments can be waterproof and dustproof. |
| Drive System | The professional industrial door HOFIC motor system consists of: high-speed motor for fast door, power supply 220V, power 0.75kw/750 rev / S, carrying large load S4 type. Loss of electric brake system; reducer; manual release mechanism; fault manual device, etc., motor constant torque output: 1, the overload capacity is strong, in some high-frequency occasions, the switch can work more than 2000 times a day. 2.The high resolution resolution of the 2,2000 lines and the fast response of the motor effectively avoid the problem of cumulative errors. 3. The manual release mechanism can be released during a fault or power failure, and the door is manually opened or closed to have an ideal position. |
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
