ECOCONTACT Package for Diaphragm Cells Chlorine/Soda Mobile short-circuiter MDC55 connection

 

ECOCONTACT Package for Diaphragm Cells Chlorine/Soda

Optimize the power circuits contacts to gain more than 5% of energy comsumption in operation and minimize maintenance costs.
Return on investment < 6 mois
For all diaphragms cells (MDC 55, LV81, H4, …)

The usage of too aggressive tools for the pickling of the contact surfaces degrades their geometry and increases their drift in time.

Example for a cell 148 kA		Voltage gain ΔU	Power saved
Anode Washers		104 mV	15,3 kW
Intercells		64 mV	9,4 kW

ECOCONTACT benefits

Total power saved per cell : 25 kW
Annual total energy gain : 25 kW x 8000h= 200 000 kWh/year/cell
Estimated kWh cost = 0,06 EUR

Annual Economic Gain : 200 000 kWh x 0,06 EUR = 12 000 EUR

Cost of ECOCONTACT equipment : 5000 EUR

Return on ECOCONTACT investment : <5 months
ECOCONTACT lifetime per connexion : > 5 years
