● 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.
The soft curtain quick 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 of anti-collision recovery. When the door body is accidentally impacted, it deviates from the track and automatically repairs the homing during the ascent. This structure not only helps the door body to operate safely and smoothly, 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.
● 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 the 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
High-strength environmental protection 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 durability is good. The curtains will not rub together to generate static electricity to attract dust. Fill the insulation material. Applicable temperature: -30~+70°C.
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.
The high resolution resolution of the
2,2000 lines and the fast response characteristics 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.
● 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
When it is not bad
High Speed Access. We offer a comprehensive range of high speed roller and high speed insulated doors for internal and external installations. High Speed Doors are ideal for high traffic areas where controlled access is required.
Save Energy & Reduce Contamination. Air leakage in industrial premises is a costly expense and ensuring you have the correct doors in operation is critical to reduce energy costs. The High speed automatic opening and closing of these rapid roll doors will provide valuable energy saving by maintaining the internal room temperature and also reduce contamination from airborne pollution and ingress of insects and vermin, essential in controlled warehouses and buildings. With a travel speed of up to 3 meters a second with some doors the operation cycle can be completed in a very short time, keeping the inside atmosphere as stable as possible all year round.
Access Control. Access control can be with remote control, radar sensors, ground loops, push button, key cards, digital code pads, finger readers and other devices to suit your individual needs in the warehouse or factory.
