Cutting costs:
that was the top topic in our customer interviews in metallurgy and chemicals. Besides efficient heating, one lever stood out: the protective gas.
The idea isnt new, but it matters more than ever. Several SARNES industrial furnaces run 24/7 with integrated endogas generation. The protective gas is produced right inside the furnace by in-built ENDO retorts.
Example: belt sintering furnace, 6,000 h/a:
- 100% nitrogen from a tank: around €48,800 per year
- Integrated endogas generation: around €13,800 per year
-> savings: appr. €35,000 per year.
Depending on the material and quality requirements, not every atmosphere is interchangeable. Where it fits, the comparison is worth making. What does your protective gas cost today? Wed be happy to run the numbers for your furnace.
