For liquid-to-liquid transfer with cross-contamination protection, the Diamondback DSU/DWU line offers a double-wall U-tube bundle design; this configuration sits within that 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 6-inch diameter shell, 48-inch shell length in a 4-pass arrangement. It carries 3/4-inch O.D. tubes. That combination is cataloged as 5-267-06-048-002. Material selection covers cast iron bonnets, steel shell, copper (double wall) tubes, and naval brass tubesheets. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Common applications are glycol-to-potable loops, process cooling where mixing cannot be tolerated, and potable water heating and cooling.
