The design and installation of ACDs are governed by specific industry standards to ensure maximum effectiveness and safety. For our global customers, our products are engineered to comply with international regulations such as the ENA Technical Specification (TS) 43-90 and the IEC (International Electrotechnical Commission) standards. These standards dictate crucial parameters, including the minimum height for installation (typically a continuous "unclimbable" surface of at least 3 meters from the ground) and the required durability of the materials. All Ningbo Changshi ACDs are manufactured with high-quality, corrosion-resistant materials to guarantee long-term performance and compliance with these essential safety requirements.
