Our History

Hexxcell Ltd. spun-off from Imperial College London in 2013 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. 

​

We developed the world’s first hybrid digital twin model for predictive maintenance of industrial thermal systems which is used by refineries and petrochemical plants worldwide to increase production, cut energy consumption and CO2 emissions, optimally manage operations and maintenance.

 

Hexxcell's clients include six of the top 10 International Oil Companies.
