How cost-effectiveness brought a client to re-equip 60 furnaces with Atherm’s immersion heaters? Use case

4 Oct, 2025

Placing an innovation is a challenge. But try re-placing something that works and even exhibits a cheaper catalogue price! If you are a plant manager with high-level requirements regarding costs, effectiveness, and environment, this story by Atherm is for you.

Asian industrials using holding furnaces for aluminum are fond of split SIC heaters. They appreciate their reliability and a relatively low cost.
At least that was the case until one of their plants discovered and adopted Atherm’s 15 kW Supratherm 55 immersion heaters.

What they got with our proprietary electric immersion heater model was an equally reliable heating solution, but more cost-efficient on the long term, since it also offered:
> lower downtime, since our heaters require almost no cleaning and maintenance
> energy savings, due to minimal thermal losses and accurate temperature control.
In addition, they got themselves an environment-friendly approach, with no CO2 generation during operations and minimized waste.

Hence, what was a more costly purchase at the starting point became much more cost-effective in only 1 year, although our client has reequipped 60 of its furnaces with Atherm’s solution.

So, if you are a plant manager and this speaks to you, please reach back. We’ll be happy to learn more about your needs.
