New BM and Improved BiTAC Generation offers Higher Performance with Easier Maintenance and Simpler Installation

EQS-Media / 07.10.2025 / 10:37 CET/CEST thyssenkrupp nucera: New BM and Improved BiTAC Generation offers Higher Performance with Easier Maintenance and Simpler Installation  The latest-generation BM2.7 v7 and improved e-BiTAC v7 electrolyzers for Chlor-Alkali electrolysis plants from thyssenkrupp nucera meet customer requirements with numerous innovative enhancements for the improvement of electrolysis processes. New designs for BM2.7 v7 and e-BiTAC v7 set innovative standards in terms of efficiency and reliability. For the first time, BM2.7 v7 and e-BiTAC v7 achieve power consumption of less than 1,960 kWh per ton of NaOH at 6 kA/m², setting a new benchmark. Newly developed tool and design solutions will reduce assembly and service downtimes of electrolyzers. Dortmund, October 7, 2025 – At its renowned Chlorine Symposium 2025 in Cologne, Germany, thyssenkrupp nucera presented the latest generation of its BM (bipolar membrane) technology and improved BiTAC (bipolar ion exchange membrane process electrolyzer) technology  for safe and efficient Chlor-Alkali electrolysis. The latest-generation electrolyzers BM2.7 v7 and improved e-BiTAC v7 achieve power consumption of less than 1,960 kWh per ton of NaOH at 6 kA/m². With this leap in performance, BM2.7 v7 and e-BiTAC v7 set new standards in specific energy consumption and contribute to more climate-friendly Chlor-Alkali electrolysis. "Uniform pressure distribution on the membrane enables more stable and efficient electrolysis, which contributes to the optimization of energy consumption and less stress on membrane," says Tsuyoshi Hamada, Director of the Okayama Branch, thyssenkrupp nucera Japan Ltd.. While BiTAC technology is a filter press concept, BM technology features a single-element design. With their different design concepts for efficient Chlor-Alkali electrolysis, different customer requirements can be met. This strategic advantage allows the worldwide leading supplier of efficient Chlor-Alkali technology to offer numerous additional performance improvements with its two Chlor-Alkali technologies BM2.7 v7 and e-BiTAC v7.
