EnPot was developed and patented by a team of researchers and engineers
from the Light Metals Research Centre, Yunca Engineering, and Energia
Potior Ltd, and is considered one of the most important breakthroughs in
aluminium smelting in 125 years.
This technology is a purpose-designed aluminium reduction cell heat exchanger systems for increasing smelter flexibility, efficiency and profitability. It offers a dynamic control of cell heat loss and balance, and provide a step change in control over production and power input requirements. EnPot Transforms aluminium potline operations by opening the operating amperage design window by:
- Allowing greater flexibility to confidently change operating state quickly and efficiently.
- Enabling response to market changes for both the short and long term.
EnPot gives smelter operators the ability to turn energy consumption up or down to take advantage of off-peak power prices, as well as accommodating the intermittency associated with renewable power supply. It also means production can be better matched to supply and demand. This technology creates flexibility by using the two modes:
INSULATING MODE - When power demand and price is high, or electricity generation is low, EnPot can be used in insulating mode to decrease energy usage below the usual design window and optimise profitability.
COOLING MODE - When power demand and price is low, or electricity generation is high, EnPot can be used in cooling mode to increase amperage above the usual design window, to maximise production and profitability.
The change in the operating state can be done can be made on a hourly, daily, weekly or monthly basis, thus allowing full flexibility over any changes in market conditions, be it short or long term.
