Flameless energizer for treatment agent
An energized assembly to enhance efficacy of a treatment agent in a local environment. The assembly includes an emanator or holder element to hold treatment agent, and a flameless energizing source to energize the treatment agent and thereby, place the treatment agent into an enhanced operational state. Preferred embodiments operate for a period of time of between about 4 and 8 hours, and can then be discarded. Typically, a housing associates the treatment agent and the energizing source. Embodiments may sometimes include one or more of: a gas-tight boundary element, a thermal transfer element, a trigger mechanism, a safety mechanism, a termination mechanism, a time-delay mechanism, solidized treatment agent to avoid spills, and a sequestering arrangement to avoid premature combination of reactants.
