A breach detection system for a container includes at least two panels having a first electrical circuit mounted thereto. The impedance circuit is a scaled version of the phase-locked loop filter. The controller is configured to adjust a temperature of the fluid flowing into an inlet of the ASC assembly by controlling an amount of oxidant injected via an oxidant injection system into the fluid upstream of the inlet of the ASC assembly based on a determination that the catalytic activity in the ASC assembly has aged. The coolant cavity can be positioned substantially around at least one of the stator end turns radially. An adhesive is provided for releasably coupling the cover to the enclosure thereby securing the cover to the enclosure along with the tightened cable tie. A modular electrochemical device is provided having a plurality of the cell tray apparatuses.
