Shell and Tube Heat Exchangers with (extremely) high pressure on the tube side, normally require a solid and exceptionally strong construction. A special construction that requires plenty of material. This all adds up in weight, energy and raw materials. Therefore, we have developed a special design known as the Compact Header Design which only needs a fraction of the material normally required for a similar Heat Exchanger. For example, the construction of an off shore rig can be significantly lighter thanks to the reduction in weight. People, Planet & Profit: less material, less energy!
