A method and a self-contained, mobile dispensing system, wherein the material to be dispensed is formed by mixing several reactants. A generator provides power to the overall system. Storage tanks are provided for storing the reactants. A chiller unit chills the reactants, and a heating unit heats the reactants. The reactants flow separately through the system until they reach a mix head nozzle operative to combine the reactants. The mix head nozzle has an elongated straight cylindrical shape and includes a plurality of orifices oriented to allow mixing of the reactants in a dispense mode of operation. A metering pump controls and supplies the reactants to the mix head nozzle, in stoichiometric proportions and at predetermined temperature and pressure. A hose connects the mixing tank to the mix head nozzle for dispensing the foam in situ.
