Fusion

Fusion systems, like fission, require exceptionally robust filtration to manage high temperature gases, radioactive particulates, tritium bearing effluents, and chemically aggressive process streams.

Porvair’s proven portfolio for nuclear fusion applications includes HEPA and pre filtration technologies, metallic HEPA filters engineered for extreme operating conditions, and fully custom filtration solutions. Each is designed to meet the stringent environmental, material compatibility, and reliability requirements expected in fusion facilities.

Our technologies play a significant role in supporting progress toward demonstrating net energy gain in fusion. By working closely with major international fusion research programmes, Porvair contributes to ensuring that critical systems operate safely, efficiently, and with the reliability necessary to advance the future of fusion energy. We operate purpose-built design, manufacturing, and testing facilities in both the UK and the USA dedicated to our nuclear product range.

Water Cooling and Vacuum Systems

Porvair delivers high‑performance filtration technologies engineered to meet the demanding requirements of nuclear cooling applications. For critical systems such as Vacuum Vessel Primary Heat Transfer and Drying Systems, our filters provide exceptional reliability, safety and operational continuity.

Our Vacuum Vessel Primary Heat Transfer System (VV PHTS) filters are designed and manufactured to comply with stringent Nuclear Pressure Equipment (ESPN) level N3 classifications. Built to withstand rigorous operating environments, these filters ensure consistent protection of sensitive heat‑transfer equipment while supporting long‑term system integrity.

In addition, our filtration solutions for Drying Systems (DYS) within cooling water infrastructure are developed to deliver dependable particulate control, safeguard downstream components and maintain system efficiency under continuous operation.
