The benefits provided by the THA and THAS series devices are possible because of a design concept that eliminates wasted space and increases operating life. This design is an outgrowth of CDE’s 20+ years of experience with MIL-grade flat electrolytics. Now re-engineered for tighter spaces and cost-effectiveness, they use state-of-the-art technology, such as laser-welded aluminum cases to eliminate the need for space wasting end-seal gaskets and a valve to allow hydrogen gas to vent which reduces swelling by relieving internal pressure.
