To me, vulcanization refers to the process of heating natural rubber to harden it by promoting cross linkages between polymer chains. I believe the process is enhanced by the presence of free sulfur.
It would involve a controlled resistive heater.
To my mind, a chemical load, if such a thing exists, would be an electrolytic cell to produce aluminum from aluminum oxide. Or a battery charger, for that matter.
Volts are still volts and amps are still amps. Equipment specs should list kVA and/or kW.
