If you are looking for a tool to melt the wax from the frames, the best devices I’ve found seem to be using steam.
My local beekeeper club has a massive stainless steel cylinder / pot that you can rent, but it was tedious to clean, takes a lot of space and was difficult to transport.
Then I was pointed to something similar as is shown in the following video.
It’s a stainless steel “funnel” that allows you to connect a hose from a steam generator (like they are used to remove wallpaper). And the nice part is that you can just add hive boxes on top to build a small tower for the frames.
There are DIY versions that use a stainless steel kitchen sink in a similar way in case you want to build it yourself.
