Fire doors and large double-leaf entrance doors inside buildings require door coordinators to ensure that the two leaves close in the correct sequence, helping prevent accidents and maintain proper control. Zhejiang Dorrenhaus Hardware Industry Co., Ltd., a Chinese manufacturer of door control hardware, is introducing its “DX02 integrated door closer and coordinator” to the Korean market. The DX02 is designed to combine door closing and sequential control in a single unit without the need for complex external control devices. Its main applications include high-traffic commercial and public facilities such as airports, railway stations, and large shopping malls, where doors are opened and closed frequently.
The unit uses a cam mechanism to improve operating efficiency and reduce resistance during opening and closing, providing smoother door movement. The product has also obtained multiple certifications for different markets, including Korean Industrial Standards certification, U.S. standards certification, U.S. fire and safety certification, and European conformity certification. The warranty period is five years for products built to U.S. standards and three years for those built to European standards. Based on its Korean and international certifications, Zhejiang Dorrenhaus plans to expand its supply network in Korea by meeting the specification requirements of large-scale construction projects and emphasizing stable door-control performance.
