KV-LITE HEFL Concentrate 1-3 % is available with medium or high expansion ratios. It is formulated with speciality hydrocarbon surfactants, stabilizers, preservatives and solvents. The formulation gives very satisfactory performance even at low temperatures. It is an efficient fire-extinguishing agent where fast coverage is essential. KV-LITE HEFL is an ideal for engine rooms, aircraft hangers, tunnels, warehouses, enclosed users, for blanketing purpose. Due to its more air percentage and less water content in the foam bubble, the finished foam has very low electrical conductivity.
Concentrate fights fire in the following ways:
- Fast spreading and coverage
- High foam stability provides blanketing effect over a longer time thereby cools the fuel surface, suppresses combustible vapour release and reduces re-kindling risk.
- Low surface tension gives superior wetting & penetrating properties to the foam concentrate. This reduces fire intensity & helps the extinguishant to penetrate the char red layer and control deep-seated fires.
- Foam layer acts as on insulating barrier, thus reduces heat radiation.
