In the test arrangement above an array of thermocouples were positioned in the sheet of metal. The sensors were wired to display an average temperature as the wand heated the steel.  Starting at 72 degrees the steel surface reached near 200F in short time as the wand was reciprocated across the width and length of the table. Steam at a temperature of 325F is generated in a Reimers electric portable boiler. Electric Steam Boilers After this steam reaches the wand the energy is released to raise the surface temperature.  Condensate water at just under 210F wets the surface adding additional cleaning power. 

Reimers is heavily doing research and testing of electric boilers used for surface sanitizing.  Reimers - Steam Room  Testing is being done on metal table tops and work surfaces using a portable steam electric boiler designed by Reimers. Using up to 100 psi the steam generated is well above the typical germ and virus killing temperature threshold.  Germs, viruses, bacteria, and fungus respond unfavorably to elevated temperatures. Hot temperatures are better suited to killing than other options and according to the World Health Organization temperatures of 140°F to 150°F are enough to kill most viruses. If materials hosting viruses are heat resistant, the recommended sterilization process is steam sterilization. It has the largest margin of safety due to reliability, consistency, and lethality. Steam sterilization is nontoxic, inexpensive, rapidly microbicidal, sporicidal, and rapidly heats and penetrates.
