5-267-12-108-001

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. Physically, the unit runs a 12-inch shell, 108-inch shell length in a 2-pass arrangement. It carries 3/4-inch O.D. tubes. That combination is cataloged as 5-267-12-108-001. Standard construction uses cast iron bonnets, steel shell, copper (double wall) tubes, and naval brass tubesheets. Design ratings run to 150 PSI on the shell side, 125 PSI on the tube side, and 375°F maximum temperature. Typical duty includes domestic water systems under double-wall codes, process cooling where mixing cannot be tolerated, and glycol-to-potable loops.
