D-Type Fire Extinguisher for Metal Fires Manufacturer in Delhi, D-Type Fire Extinguisher for Metal Fires Manufacturer Supplier in Delhi, D-Type Fire Extinguisher for Metal Fires Wholesale in Delhi, Cost-Efficient D-Type Fire Extinguisher in West Delhi, High-Quality Fire Safety Solutions in West Delhi, D-Type Fire Extinguishers in West Delhi

D-Type Fire Extinguishers are specialized firefighting devices designed specifically to combat Class D fires, which involve flammable metals such as magnesium, titanium, sodium, lithium, aluminium, and potassium. These fires burn at extremely high temperatures and react violently with water or standard extinguishing agents, making D-type extinguishers essential in such cases. D-Type Fire Extinguisher provides special options that deal with the complex and perilous face of metal fires. Unlike conventional extinguishers, D-Type models are specially designed to contain Class D fires which include metals such as Lithium, Sodium, Potassium, and Magnesium.These extinguishers are blamelessly designed with a low-pressure nozzle and squeeze grip valve that allows controlled and precise application even in critical danger areas. We cater to large industrial setups or mid-size labs needing a scalable safety solution without compromising on quality. Each extinguisher carries ISI certification and is tried under supremely demanding conditions ensuring performance under extreme conditions.

D-Type Fire Extinguishers are engineered with precise specifications to safely suppress fires involving flammable metals. These extinguishers typically come in capacities ranging from 5 kg to 10 kg, depending on the application and area coverage. They use specialized dry powder agents such as sodium chloride, copper-based powder, or graphite powder, chosen based on the specific type of combustible metal present.The extinguisher body is constructed from corrosion-resistant steel, designed to withstand harsh industrial environments, and includes a long-range applicator nozzle or low-velocity discharge lance to allow the operator to apply the powder from a safe distance, minimizing the risk of disturbing the burning metal. The working pressure is typically 7 to 15 bar, and the unit is manually operated, often with a squeeze grip valve and safety pin for quick activation.These extinguishers are color-coded with a yellow label for easy identification and comply with international and regional fire safety standards such as IS: 11833 or equivalent. Their discharge time and flow rate are specifically designed to gently coat the burning material without spreading molten metal or sparks, ensuring safe and effective fire control in high-risk environments.D-Type Fire Extinguishers are commonly used in metalworking and manufacturing facilities, where metals like magnesium, aluminium, titanium, and sodium are processed through welding, casting, or grinding. They are also vital in the aerospace and aviation industry, used during aircraft maintenance or aerospace manufacturing, where the risk of metal fires is high. In chemical laboratories and mining plants, where reactive metals are handled or extracted, D-Type extinguishers provide effective fire suppression.
