A device and method for converting a consumable into an aerosol with high heat without burning the consumable by packaging the consumable containing an internal susceptor inside an encasement with an induction heating element wrapped around the consumable-containing package to heat the susceptor using a magnetic field generated by the induction heating element. Combustion of the consumable-containing package is minimized by limiting air inside the consumable-containing package by coating a plurality of holes in the encasement material that melts at high temperatures. The coating may also include a flavoring.

The present technology is directed to multi-frequency controllers for inductive heating and associated systems and methods. The systems can be configured to precisely heat a module via a coil to a target temperature using oscillating, pulsed electrical signals associated with unique frequencies and/or capacitance values. Each unique frequency can correspond to heating the module to a particular depth, relative to an outer surface of the module. A first pulsed electrical signal having a first frequency can heat the module to a first depth, and a second pulsed electrical signal having a second frequency can heat the module to a second depth different than the first depth. The system can include a thermal sensor for measuring a temperature associated with at least one of the module or a fluid associated with the module. Based on the temperature, the system can adjust signal delivery parameters of the first and/or second electrical signals.

A vapor delivery device includes an induction coil system. The induction coil system can include a coiled fluid tube, a coiled wire, a capsule between the coiled fluid tube and the wire, and a cooling fluid supply configured to force a cooling fluid through the capsule across the coiled wire.
