Liquid nitrogen distribution ‘valve boxes’
GRE won a UKRI / STFC contract to redesign and manufacture 8 multi-channel LN2 valve boxes, to replace failing units already onsite. The valves boxes were required to split a single liquid nitrogen input into

Custom cryostat for gas stream pre-cooling (hydrogen reprocessing application)
GRE were contracted to design and manufacture two custom cryostats for CCFE (Culham Centre for Fusion Energy – part of the UK Atomic Energy Authority). Each cryostat comprised a cooled, vacuum insulated, cryostat vessel with

Custom Cryostat, for sample testing
GRE were contracted to design and manufacture a custom cryostat for NPL (National Physical Laboratory), which comprised a cooled (with a Sumitomo cryocooler), vacuum insulated, cryostat vessel with removable sample holder and temperature control via

Aerogel – insulated, Liquid Nitrogen Dip Tank (food processing)
GRE was contracted to redesign / remanufacture two liquid nitrogen dip tanks for use in the food processing industry (to produce a nice, crisp, chocolate shell for a well-known ice cream brand). The client’s previous

Argon Reliquefier / Purifier
GRE were contracted by the Physics Department at the University of Manchester to design a machine for scrubbing/cleaning/purifying argon gas resulting from a test process. Project Goals The requirement was to take contaminated

Mobile, cryogenic laser amplifier head cooling system
Case Study: Cryogenic Lens Cooling System for High‑Powered Laser Applications Overview GRE was awarded a public tender by the Science and Technology Facilities Council to design and manufacture a mobile, helium‑based, amplifier lens cooling

Cryogenic cooling system for fusion reactor
Case Study: Development of a Liquid Nitrogen Distribution & Multi‑Channel Cooling System Project Overview Tokamak Energy Ltd required an advanced cryogenic cooling system to support their nuclear fusion research, where plasma temperatures approached 100 million

Thermal Shroud Set for Satellite Test (Vacuum) Chambers (T-VAC)
Project for the Science and Technology Facilities Council – Rutherford Appleton Laboratory (RAL Space) Overview Green Resource Engineering (GRE) was awarded a contract by the UK’s Science and Technology Facilities Council (STFC) to design and

Laser amplifier head cooling system / cryostat; case study
Design details GRE won a UKRI contract (for the UK’s Central Laser Facility, but with the equipment ultimately destined for the XFEL laser research centre in Germany) to design, manufacture, test and install two cryogenic cooling / temperature control systems (cryostats) for
