In 2020 Harrison Pneumatics Celebrates 40 years in business producing industrial control systems & offering a second to none subcontract manufacturing solution to the fluid and motion industries. To mark this historic milestone, we have recently moved to new larger premises; merging our HP Systems division in the South East with our South West manufacturing and distribution centre. So we are now fully based in the South West and proud to be contributing to the growth and development of manufacturing here in North Devon and in the UK. We continue to work for a wide range of customers and sectors both at home and abroad, from global household names to industrious start-ups and we continue as ever to help all our customers achieve their goals.

We can offer design or build to your specifications; from purely electrical control systems, to purely pneumatic panels and everything in-between including small assemblies, looms and kitting services. We are an established centre of Engineering services and solutions.

We readily engage in research and development that improves, safety, efficiencies and reliability within industries that impact all of us.
We are passionate, we are connected to what we do and who we do it for and how that impacts the world we live in; whether the first critical link in a supply chain that will ultimately lead to influencing the performance of a Formula 1 race car, or how energy from renewable resources is generated or whether its finding the solution to how a farmer keeps his dairy running, or how a factory reduces its waste, cost and emissions.   The engineering challenges you face, we face together.

We now bring you this expertise, knowledge and passion through our Harrison Pneumatics distribution centre and web store; bringing you only the brands we have tested and use and trust. We aim to help our customers get the most out of their products, quickly and easily, with honest advice, enabling them to drive down the total cost of ownership and feel supported.
