Say goodbye to ‘partial load’ energy loss
Say hello to savings
Is your melting furnace showing high energy consumption values with low utilization? Ifs so, you are not alone. Many aluminium foundries don’t melt at a 100 % capacity, for example during the start-up phase of a project, maintenance work carried out on the casting machines or when planning future capacity. During this time, the melting furnace often operates at only 30 to 75% of its capacity.
This can lead to several short melting periods within one shift of production. Short melting periods are not very efficient, as the energy-intensive process of liquefying metal is interrupted again and again.
The Part Load Efficiency Control (PLEC) puts a stop to this by automatically optimizes “melting” and “holding” operating modes according to utilization. This switch to longer melting periods has been proven to reduce energy consumption by up to 20%.
Four features for big benefits
1. Clever control for smart savings
PLEC automatically controls the furnace ‘melting’ and ‘holding’ modes to strike exactly the right balance for optimal energy consumption, and to eliminate stop/start wastage.
2. Cover up to keep energy down
Whenever ‘holding’ mode in selected, another key feature of the PLEC is that it integrates with your furnace’s shaft laser to automatically close the shaft cover in order to maximise heat retention.
3. Free melting made simple
In your daily business, the PLEC automatically commences free melting at the time you scheduled – an essential daily process to ensure dross removal.
4. The perfect bath for optimal results
Finally, the PLEC takes into account how full the bath should be at the start of the free melting process, and co-ordinates furnace controls to ensure the correct fill level is achieved when this process is scheduled to commence.
Options
Integrates perfectly with:
- Shaft laser
- Bath fill laser
