Maintenance Cost
- SESPI Chloropure electrolyzer is comprised of an intermeshed electrode assembly that is fully enclosed within an FRP housing, as shown

- Leaks are very uncommon and never noticed
- CTE cells must be replaced every 3-5 years due to wear of anode coating. Chloropure cells are proven to last 6-8 years in normal operation with routine acid cleaning
- On average, one faulty CTE cell is replaced every month per electrolyzer due to mechanical problems with leaks, gaskets, and corrosion. In comparison, a Chloropure electrolyzer may need to be repaired 1 or 2 times between the 6-8 year cell replacement cycles.
- Average annual maintenance cost for 500 kg/hr system (electrolyzer components only - excluding cost of labour):
CTE - $ 650,000 (12x10 spare cells + complete replacement for coating)
Chloropure - $ 100,000 (Inspection, gaskets, spare anodes & cathodes)
Annual Maintenance Savings with Chloropure®- $550,000
