Advantage # 1
Due to their design the Dynamo dry hearth furnace charging chamber has no molten metal in it, thus it virtually eliminates the dangers of metal splash.
The charging chamber is angled downwards and as the metal melts it runs into the metal bath.
Advantage # 2
Due to the innovative design the Dynamo dry hearth furnace the drop in temperature when adding cold ingots or scrap (blue color) to the metal bath (red color) is virtually eliminated.
Less drop in temperature means a more consistent temperature which translates to better castings and less scrap.
Advantage # 3
The dry hearth design features 27% efficiency. In comparison, a crucible furnace has 20% efficiency.
