Suitable for food, medicine, electronics, rubber, chemical, automobile, textile, logistics and other fields. High speed roll up doors are controlled by PLC, inverter, and encoder (PVC material) to quickly lift the door curtains. It has the characteristics of fast, safe and reliable. In addition to being used in general workshops, it can also be used in medicine, food, electronics, clean workshops (class 1000 to 100,000), purification workshops, cigarettes, printing, textiles, supermarkets and other light industrial workshops. Regional isolation and any other places that require quick access, with the development of high speed roll up doors, more and more brands have entered the Chinese market, and more and more people have paid attention to them. It is designed and accurately positioned an industrial door, mostly used in places with high environmental requirements such as food, electronics, printing, etc., the main function is to quickly isolate the air to ensure the dust-free level of air quality in the workshop.
