FORMERLY KNOWN AS: KV-OLFEX.
POTASSIUM BI-CARBONATE UREA REACTION COMPLEX
KV-LITE POWEREX is a dry chemical powder based on Potassium Allophonate, a reaction product of Potassium Bi-Carbonate–Urea. It was developed, registered and patented by Scientists of ISRO, Dept. of Space-Govt of India. We are licensed to manufacture this product under Technology Transfer Agreement.
EXTINGUISHING MECHANISM:
It possesses the unique property of decrepitation where powder particles break down into large number of minute particles in the flame zone thereby surface area of the powder in the combustion zone increases manifold.
Fire extinguishing efficiency is dependent on the rate of removal of free radicals, which is directly proportionate to the surface area of contact i.e. larger the surface area of powder; faster is the extinguishment.
Large surface can also be achieved by grinding the powder to very fine size. But fine powder will pose problem of compaction during storage & also the projection difficulties. Further, there is limitation beyond which powder cannot be ground. This limitation is overcome by decrepitation property of KV-LITE POWEREX which is unattainable by other conventional powders.
KV-LITE POWEREX is recommended for large B & C class fires involving inflammable liquids where fast extinguishment is called for in order to save lives and properties.
It can be used in conventional Portable Extinguishers, Wheeled Units, Fire Trucks, Fixed Installations & Powder Cannons. Its Application Density is low; hence required charge in extinguisher will be approx. 60% lower.
