5-267-12-060-001

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. Its envelope centers on a 12-inch diameter shell, 60-inch shell length in a 2-pass arrangement. It carries 3/4-inch O.D. tubes. That combination is cataloged as 5-267-12-060-001. The build specifies cast iron bonnets, steel shell, copper (double wall) tubes, and naval brass tubesheets. On the ratings side, expect 150 PSI on the shell side, 125 PSI on the tube side, and 375°F maximum temperature.
