  • Micro-module cabinet fire protection equipment

    Micro-module cabinet fire protection equipment

    Targeted micro-enclosure suppression is a pre-engineered fire protection approach designed for cabinet-level risks. Most electrical and industrial fires start in the hidden confines of equipment enclosures – inside control panels, server racks, battery cabinets, and machinery housings – rather than out in the open space. These micro-environments pose a unique challenge: a fire can ignite and grow unnoticed. A complete Detection & Suppression pre-engineered system for Electrical Cabinets • CO2 or FM-200 Extinguishing Agent • Easy / Flexible Installation • Quick & Effective Suppression • No electricity or moving parts • Highly economical Reduces even the most critical electrical fire risks: • Combustion. At Astro Fire Systems, we provide smart, automatic fire suppression solutions tailored to protect these critical systems, before a minor fault becomes a major fire. Enclosures can conceal the early signs of a fire. Our wide range allows you to choose between the use of CO 2, FK-5-1-12 extinguishing agent or HFC-227 extinguishing. With the AF-X Fireblocker, you can protect electrical cabinets easily and cost-effectively.
