5-267-10-108-002

A double-wall U-tube bundle gives this configuration the thermal and mechanical margin expected of Diamondback DSU/DWU equipment in liquid-to-liquid transfer with cross-contamination protection. 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 10-inch shell, 108-inch shell length in a 4-pass arrangement. It carries 3/4-inch O.D. tubes. That combination is cataloged as 5-267-10-108-002. Material selection covers 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. Installations range across process cooling where mixing cannot be tolerated, glycol-to-potable loops, and potable water heating and cooling.
