Thermoelectric Conversion Systems Ltd. (TCS) is a technology SME operating out of Clydebank Business Park, situated a few miles to the North­west of Glasgow. We specialise in the development and application of thermoelectric technology to heating, cooling and power generation applications. Recently we have started manufacturing and selling extremely high performance (CoP > 10) heat pumps up to 20KW rating. 

We provide a very wide range of thermoelectric power generation & conversion products, cooling products and associated technologies to the electronics, automotive, medical, industrial and academic sectors. In addition to our standard range of products we also offer a comprehensive testing service, general consultancy on thermal and electronic systems, and the design and manufacture of bespoke test equipment, heat pumps and cooling systems. We have a flexible approach to customer engagement and offer a rapid turn­around for prototyping and sample production.

Our premises have recently been completely refurbished and comprises the main office area (including kitchen and meeting room), laboratory, manufacturing, storage and loading bay areas. We also have a well­equipped mecanical workshop. We design and manufacture all our products in­house and export world­wide. If visiting by car there is plenty of free parking immediately in front of the building and if by train, the nearest station is Singer Station (a couple of hundred yards’ walk).

Dr Andrew Knox B.Sc., Ph.D., C.Eng., F.I.Mech.E, F.I.E.E., F.I.E.S., F.R.S.E. – Technical Director of TCS Ltd. Andrew founded TCS Ltd in 2015 with a number of his former Ph.D. and post-doctoral students. He leads the company’s Research and Development activities for thermoelectric heat pumps, power generation and cooling systems. He has an Honours degree and Ph.D in Electrical and Electronic Engineering from Glasgow University. His Ph.D. work investigated the impact of 3-D electron velocity distribution and space charge effects in high voltage electromagnetic beam focussing for CRT displays. In the early 80’s Andrew worked at Ferranti Ltd in electronics and embedded software systems. From 1985 to 2007 Andrew worked in IBM in a number of roles including as a Research Staff Member and latterly as a Senior Technical Staff Member with world-wide responsibility for computer display technologies. In 2007 he moved to Glasgow University as Professor of Power Electronics and shortly thereafter formed the university’s Thermoelectrics Research Group. Whilst at Glasgow he led several £multi-million projects for InnovateUK, EPSRC and the E.U. into industrial applications of thermoelectrics. He was a co-founder of the UK’s EPSRC-funded “TEMPEST” network that brought together the UK’s academic and industrial leaders in the thermoelectrics field. He also served on the National Physical Laboratory’s Advisory Board for Thermoelectrics and co-authored the UK Thermoelectrics Roadmap. Andrew has worked as an engineer and physicist for his entire career. He is a Chartered Engineer (C.Eng.) and Chartered Physicist (C.Phys), a Member of the Institute of Phyics (M.Inst.P), a Senior Member of the Institute of Electrical and Electronic Engineers (SMIEEE), and a Fellow of the Institution of Electrical Engineers (FIEE), the Institute of Mechanical Engineers (FIMechE), the Institution of Engineers in Scotland (FIES) and the Royal Society of Edinburgh (FRSE). He holds over 60 patents and has published over 100 peer-reviewed papers covering a diverse range of topics including thermoelectrics, computer architecture and display technologies. Outside of work he has served as a non-exec director, as a Trustee of a charity, as the Chairman of the Meccano Society of Scotland and was awarded the Sir Alec Issigonis Shield in 2017. In 2019 Andrew took early retirement from Glasgow University and now works full time in the company.

Dr Jonathan Siviter C.Eng. M.Eng. Ph.D – Managing Director. Jonathan holds a first degree in Electrical Engineering and a PhD thermoelectric heat pumping. He has previously worked in Doosan Babcock (thermal power plants). He is one of the founders of TCS Ltd and currently holds an Enterprise Fellowship from the Royal Academy of Engineering. Jonathan co-founded TCS in 2015 and leads the business development and marketing activities.

Mrs Elaine McNamara BA is the company’s financial and administration manager, along with being a director. Her degree is in Business Law and HR Management. She has over 30 years’ experience in business management and administration in addition to her expertise in contracts, compliance with employment legislation and project management.
