Benefits of using Chlorine FeCl2/3 regeneration
• Less electrical energy needed for regeneration
• Well known chemical method for regeneration
• Method without chemical side reaction products
• Constant etching rate = stability of etching quality “quick reaction”
• Reduced refinishing / operating / personnel costs
• More than 95% of all technical problems are eliminated by trouble-shootings through mail or skype
• The modular design can be adapted to any etching rate capacity
• Automatic control of the regeneration: starts and stops depending on the etching rate of production (ORP controlled)

Regeneration energy input: electrolysis vs chlorine gas
Electrolysis (240 kg etched Fe / d)
• 4 electrolysis w. 12 kg etched material / h (operation time 20 h / d)
• 15,8 kWh / 1 kg etched Fe 3.800 kWh / d
Chlorine gas (240 kg etched Fe / d)
• 0,13 € / kWh
• 0,26 € / kWh
• + 100,00 € / d HCl
594,00 € / d or 1.088,00 € / d
Running costs 203.400 € / year
(assumption 0,13 € / kWh)
• 460 kg / Cl2 per d • Without evaporator
• 492,00 € / d
• With evaporator • 0,13 € / kWh
23 kg / Cl2 per h 500,00 € / d
494,00 € / d 988,00 € / d
• 0,26 € / kWh
For 1 kg Chlorine 270 KJ or 0,12 kWh
506,00 € / d electric power is needed
Running costs 139.200 € / year
(assumption 0,13 € / kWh)
