About Us

PDM Analysis Ltd develops, markets and supports SCORGTM, a unique software for the design and analysis of positive displacement machines such as screw compressors, expanders, pumps and motors. We are focused on supporting industry and academia with our software tools and services for easy and accurate insight into the performance and design of positive displacement machines.

Company history

Founded in 2014, PDM Analysis Ltd is applying the success of researchers at  City University of London by marketing and further developing SCORGTM. We have over 25 years of experience in the field of screw compressors through collaboration with a large portfolio of leading manufacturers, research centres and universities on providing solutions for the efficient design and operation of positive displacement machines. We pioneered the use of 3D Computational Fluid Dynamics for screw compressors and developed SCORGTM more than 15 years ago at City, University of London.

 

A version of the SCORG software was originally developed by scientists working at City, University of London. PDM Analysis Ltd is exclusively licensed by City, University of London to continue the development and implementation of SCORGTM. We closely collaborate with Centre for Compressor Technology. PDM Analysis Limited is an independent company and is solely responsible for the commercialisation of SCORG. City, University of London welcomes PDM Analysis Limited’s commitment to commercialise SCORG for the benefit of society.

Today we are the market leader in providing solutions for the analysis and design of screw machines.
