What are the Applications of our High Speed Doors?                                           

Widely used in factories, workshops, warehouses, which in the field of food, chemical, textile, refrigeration, electronics,
printing, supermarkets, assembly, precision machinery, logistics, warehousing and etc.

Hongfa  High Speed Doors Characteristics :                                                        

1. Electric control system: use c102 dual core dual cpu frequency conversion control system of Danfoss; Power
Supply: 220v, power: 1.5kw, high performance, high reliability, high stability, high precision positioning and so on.
At the same time, it use frequency conversion control technology, soft start, slow stop function to ensure the door
operate smoothly and increase service life.

2. Opening and closing speed: 0.6-1.5m/s opening speed (adjustable), 1000-1500 HF open times / day.

3. Safety devices: mounting a couple of infrared photoelectric protection switch in the lower of doorframe, when
people
or objects stays below the door, the door does not fall, complete with crash column.

4. The effect of resist wind: Use high-strength antioxidant aluminum alloy specialized wind lever, counterweight
plate along with German standard.

5. The replac function of curtain: the convergence parts of curtain with aluminum ribs strips, no matter which part
of curtain is broken, you can easily replac and than save cost.

6. Welding: Using the latest high-frequency welding technology, automatic stitching forming in first time, seam neatly,
no wrinkles, no knife scraping traces, the splice surface is smooth, will never open.

7. Control mode: photoelectric protection, internal and external button control, radar control, double door interlock.

8. Long Service Life: High-speed doors are designed for being used very frequently. Design characteristics such as the
spiral technology or the weight balance provide for a long service life.
