Modular Shell-and-Tube Heat-Exchangers (MSTHE) Modular shell-and-tube heat-exchangers (MSTHE) are very versatile. A single unit can be assembled into multi-module configurations in order to match a huge range of process requirements. I have been involved with this technology since 1988 when I worked as a Thermal Design Engineer for a small specialist heat-exchanger manufacturer in South Africa. I developed their unique design and selection software, and optimized a number of novel, new technologies. I have always been fascinated by its flexibility – the heat-exchanger version of a Meccano set. They can be assembled quickly using off-the-shelf components. Some of their unique features include a spiral cage assembly, elastomeric seals and airgap between tubeside and shellside fluids. In later years I purchased this technology from a large distributor which had acquired the company some years prior. A few examples are shown below.
