A 3 kg CO₂ fire extinguisher is a high-pressure, stored-pressure unit using carbon dioxide (CO₂) as the extinguishing medium. It is ideal for Class B (flammable liquids) and electrical / energized (Class C / E) fire risks. CO₂ extinguishes fires by displacing oxygen and rapidly cooling the fire zone, and leaves no residue, which makes it suited for areas with sensitive equipment (servers, control panels). Key Features: Residue-free extinguishing — leaves no powder or mess; safe for electronics, machinery, and sensitive installations; High-pressure CO₂ agent — working pressures around 154 bar, tested to ~250 bar for safety and reliability; Effective for Class B & Electrical fire types — ideal in labs, server rooms, offices, workshops; Wide operating temperature range — many models support –30°C to +60°C, enabling use in both cold and warm environments; Robust construction — cylinder material (carbon steel or alloy), seam integrity, and horn design ensure durability and safety; Quick action — discharge times typically in the 8–12 second range, with effective throw distances of ~1–3 meters. Industrial Uses / Applications: Data centers, server / telecom rooms; Electrical control rooms, switchboards, panels; Laboratories with flammable liquids and sensitive instruments; Offices with electronic equipment; Workshops handling solvent / flammable liquid spills; Marine / shipboard electrical compartments.
