is above all the solution for problem fires, such as in the plastics processing industry, in recycling plants, on landfill sites or also in particular for the storage of lithium-ion batteries. The gel can be easily sprayed onto the source of the fire and forms a cooling and air-impermeable layer there so that the fire is smothered. The composition of the gel is such that it adheres even to difficult surfaces. This ensures optimal extinguishing over the entire surface. In addition to effective and rapid extinguishing, these special gel series Jockel extinguishers can also be used as a preventive measure. Objects treated with this gel can hardly be ignited. The extinguishing gel evaporates almost residue-free.
