Configured for liquid-to-liquid transfer with cross-contamination protection, this configuration carries the double-wall U-tube bundle construction that defines the Diamondback DSU/DWU range. Each tube is vented to atmosphere through a diamond-pattern air gap, so a failure in either wall reports itself outside the unit. The configuration measures 8 inches across the shell, 84-inch shell length in a 4-pass arrangement. It carries 3/4-inch O.D. tubes. That combination is cataloged as 5-267-08-084-002. As furnished, materials include cast iron bonnets, steel shell, copper (double wall) tubes, and naval brass tubesheets. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature.
