HRS Heat Exchangers AHED (Advanced Heat Exchanger Design) system

Software for the design of shell and tube heat exchangers has been further enhanced after its first update introduced a Tube Assistant feature, making more information instantly accessible to users during the design process.

AHED (Advanced Heat Exchanger Design) was officially launched in December 2020 and has been specifically designed to bring the latest theories and design techniques to a wide group of potential users, from students and academics through to industrial engineers and system designers.

One of the key features of the collaborative, cloud-based AHED system is its database of 2000 different fluids, meaning that key property parameters are available to users without the need to look things up outside of the system. In January 2021, a new AHED system update introduced another database in the form of the Tube Assistant.

Updated versions of AHED now feature a ‘magic wand’ symbol in the geometry section of the program. Clicking on this opens the Tube Assistant feature, which contains details of different tube dimensions, including those commonly used for heat exchangers, as well as standard ISO, ANSI and millimetre metric tube types. Fields in the table correspond to a specific tube outer diameter and wall thickness. Selecting the appropriate field then allocates these dimensions to the shell, inner tube or nozzle in the current AHED project as required.
