Nabco provides optimum automatic door systems suitable for various locations such as food processing plants and hospitals where sanitary control is required. Due to changes in eating habits, the internationalization of the production and distribution of farm products, and the increase of imported food, the number of different types of food poisoning affecting consumers has been on the rise. The types of food poisoning related to sanitary control such as food poisoning caused by Salmonella, O157, and staphylococcus aureus have been increasing year by year. Taking measures to prevent incidents such as the inclusion of foreign materials in food is also very important. Nowadays, many food manufacturers are adopting a new quality control system called HACCP. In addition, hospitals and similar facilities are constantly subject to the risk of intramural infection. In response to this, they need to adopt effective sanitary control systems. Being optimized systems, NABCO automatic doors not only both open and close, they also contribute to the sanitary control of various sites such as food processing plants and hospitals.
