B-1204-D4-O

This B Series unit is configured for reliable water-to-oil cooling, and B-1204-D4-O combines serviceable construction with durable materials. The unit is arranged as a one-pass exchanger and is built around a 6.13-inch shell, 36-inch shell length, and roughly 42.28-inch overall length. Material selection for this configuration includes a Brass hub, Brass shell, 0.25-inch Copper tubes, Cast Iron bonnets, and optional zinc protection. Ratings include 250 PSI maximum shell-side pressure, 150 PSI tube-side pressure, and a 350°F maximum operating temperature. These exchangers are frequently applied to hydraulic oil cooling, lubrication circuits, and general industrial heat rejection. Material options such as copper nickel tubes, bronze bonnets, and zinc anodes expand its usefulness in harsher water conditions.
