How it works

Heating
Heating in the heart of aluminum is the challenge, for that, you need to:
– Transport electricity
– Convert it to heat
– Transmit heat into the metal
– Have a reliable system
– Have a good life time
Immersion heaters, advantages
– High metallurgical quality and purity, less corundum (no over heating)
– Up to 40% energy saving with 100% yield (heat directly in the bath)
– Accurate regulation of bath temperature
– Temperature homogeneity (good for certain aluminium type)
– No CO2 emissions
– Usable for maintaining and reheating temperature
