Just a thought- Induction hot water heater(?)

[Stan]

The drum heater at the above link has an interesting thing in their ad. It says that it works on plastic, metal or fiber drums.

Well, it looks like to me, that they use a container of fluid as a "ring" around the barrel, so the induction is happening inside their "ring", not inside the container, and then it heats the container, most likely by conduction.  That would allow you to heat a barrel made out of any material, but not really DIRECTLY by induction.  Christy Hicks

Umm, two different products advertised on that page.

The "induction drum heater" is for steel drums, you know, the 55-gallon kind.  Induction, of course, will work fine on a steel drum.

The product that works on plastic and fiber is the "LMK Flexible Heating Jacket", which is an entirely different animal that does not work by induction.

FWIW.

Induction drum heater only work over steel barrel.

However to heat plastic drum or any non conductive materials they have non induction type which is band wrap heater, It is available either wire resistance or liquid or freon flow band wrap.

Please read the link completely...too fully understand what induction is.

You can take a high current transformer or rewind with heavier gauge wire and cut off the core end. Then mount the cut surface end with winding to steel surface of plate that is welded to drum or tank.

Now have power box to produce high frequency high current output and connect to modified transformer.

FWIW
