A new lightweight gas-particle mixture generator for fire-extinguishing purposes is designed such as to keep the generator and aerosol temperatures low by including a Phase Change Materials (PCM) component. The new generator performances have been studied experimentally and compared to the corresponding performances of a traditional design. The temperature evolution profiles of this gas-particle mixture generator, operating pressure, mass flow rate and the total discharge weight, were characterized experimentally. The re-design, resulted in 30% decrease in the total weight, a significant decrease of the wall operation temperature and also a decrease of the generated aerosol temperature. Therefore, this concept shows a promising alternative.
