Both solutions can provide suitable atmospheres for heat treatment. The correct choice must consider required flow rate, consumable costs, operating continuity, gas composition and production flexibility.
Technical comparison
A nitrogen-methanol atmosphere is produced by mixing nitrogen with vaporised methanol to obtain a composition similar to endogas. An endogas generator instead produces the atmosphere continuously, mainly from natural gas.
- Qualità e disponibilità of consumabili
- Composition stability
- Ability to adapt the atmosphere to the process
- Sicurezza e gestione dell’system
Confronto economico
The real cost does not depend only on the initial investment. Natural gas, nitrogen, methanol, electricity, depreciation and annual operating hours must all be considered. At medium-to-high flow rates and with continuous operation, an endogas generator can provide a lower specific cost.
- Average and maximum flow rate
- Annual operating hours
- Prezzo aggiornato of vettori energetici
- Storage and distribution costs
Quando valutare ciascuna solution
Nitrogen-methanol can be attractive for low flow rates, intermittent use or particular logistical conditions. A generator is generally more competitive when atmosphere demand is high and continuous.
