Thermo-55 is a solvent-based, heat-activated odor counteractant specially formulated for application using a thermal fogging apparatus. Utilizing a blend of highly purified petroleum solvents and odor-controlling essential oils, Thermo-55 creates a vapor barrier that prevents malodors from finding their way into the living environment. Solvent-based Thermo-55 is especially effective for controlling odors associated with structural fires. It is also highly effective for tobacco-related odor removal. Its special solvent formula duplicates the passage of smoke, neutralizing its effect.
