Every figure in these tables is taken from the factory sheets in the product folder and is written in English. 1 metric ton = 1.102 US short tons. Power-supply ratings can still be negotiated to the customer requirement, as the sheet itself states. American standards are the US specifications normally requested with this equipment.

Double power supply, one-to-two — factory sheet| No. | Catalog statement |
|---|
| 1 | Continuous batch production from two sets of power control |
| 2 | Large-piece casting with lower unit power use and a higher power factor |
| 3 | Non-stop melting: hold temperature when needed, higher equipment use |
| 4 | Both furnaces can be preheated and sintered at the same time |
| 5 | Small footprint, simpler installation and maintenance |
| 6 | If one supply or one furnace stops, the other can be swapped in |
