Abstract
A cell of a recuperator has a passage therein having a first end and a second end. In use a fluid passes through the passage under pressure. The cell must be tested to determine an operational efficiency or leakage within the passage. A pair of sealing mechanisms is positioned at a respective one of the first end and the second end of the passage. A vacuum is pulled across the passage and a rate of leakage is monitored to define an operational cell and a failed cell.
