ET Double-Track Plus: ET Double-Track Plus is the most versatile double output power supply available in the market today. The unique feature is the capability of the system for sharing the power with a stand-by (3rd) furnace, thus ensuring the uninterrupted continuation of metal production even when one of the furnaces is under re-lining/sintering/maintenance. This feature makes ET Double-Track plus a double output power supply in a real, complete, and comprehensive sense of the word making it far superior to any of the competitive products. The seamless electronic integration eliminates the need for any kind of mechanical switching for the selection of furnaces. If the need arises at any given point of time for a larger quantum of metal to be made available, power can be given to all the three crucibles simultaneously in the required ratio, within the limits of overall rated power, and the metal from all the three furnaces can be tapped at a time to ensure a larger single batch of liquid metal.
