About Us

Hexxcell Ltd. spun-off in 2013, acquiring technology developed at Imperial College London during a large-scale industrial research project, to deliver technology and services to industry in the area of advanced heat transfer and, in particular, crude oil fouling mitigation.

Ever since, we have developed our technology in large scale multidisciplinary R&D projects in collaboration with oil majors and validated extensively on their plants.We are now an independent private company based in Central London and a proud team of chemical, mechanical and process systems engineers with deep domain knowledge of heat transfer, mathematical modelling, artificial intelligence and a knack for data science.​

True to our origins, we keep innovating everyday, pushing the boundaries of what industrial software can do.


To make this component work with other components you must:
  1. Add a background color to each section div on this page. This will ensure that the progress bar does not appear in other sections of the page.
  2. Make sure this page uses a page-wrapper div to wrap all components on the page. This, along with step 3, makes it possible to edit the content inside of the timeline.
  3. Add the timeline-on-page class to the page-wrapper and the main-wrapper class. This, along with step 2, makes it possible to edit the content inside of the timeline.
