The Electric Furnace.

Electric Furnace Usage

An Electric Furnace (right) receiving EU from a Generator and BatBox.

The Electric Furnace is an improved version of the Iron Furnace. The benefits of this device compared to the Iron Furnace are that the Electric Furnace is faster, and being an IC2 machine, can be overclocked. By running on electricity instead of burning items, it is able to shut off immediately upon finishing (thus avoiding wasted energy). You can best take advantage of this by having some form of energy storage between the Electric Furnace and the Generators, such as a BatBox. It may also be powered by redstone dust, like other IC2 processing machines.

The four slots on the right are used to place upgrades in the machine. The three upgrades that are available are the Overclocker Upgrade, the Transformer Upgrade and the Energy Storage Upgrade. You can stack upgrades, but there is no use having more than 4 transformer upgrades or 13 overclocker upgrades. Powering the machine with more than 10 overclockers requires an energy storage upgrade.

The following table shows the exact time in ticks required per operation to number of overclockers and the required EU/t to power the macerator. Note that in-game, processing time is rounded to the nearest tick and EU/t is rounded down to the nearest whole number, from each of their formulas to calculate their respective values. And finally, the operations per second column is derived from the exact time values of the seconds per operation column, where ~ indicates a rounded down approximation while = indicates a value that happens to be the exact number shown.
