Case Studies
Vacuum insulated pipework (SIVL)

Multi-channel SIVL
Design challenge As part of a complete LN2 cooling system for Tokamak Energy’s ST40 fusion reactor, GRE needed to supply 10 separate LN2 cooling channels, each of which had its own separate exhaust line. With restricted space, there was little to no

Liquid Hydrogen transfer lines
Design details GRE was contracted to design and manufacture super-insulated, liquid hydrogen fill and vent lines for a vacuum insulated LH2 storage tank. This design study arose from the client’s experience with other SIVL manufacturers, who appeared

Replacement SIVL – liquid nitrogen gas vent / isolation valves / pressure relief valve train
In addition to large concept design and analysis projects, GRE also produces many small vacuum insulated pipework sub-assemblies and lines, where clients either need a routine replacement or performance improvement. In this instance, the client was experiencing

Liquid nitrogen distribution system for pharmaceutical freeze dryers
Design details GRE was contracted, by one of the UK’s leading M and E contractors, to design, manufacture and install a liquid nitrogen distribution system to feed two freeze driers used in the vaccine manufacture and storage process. The

Liquid nitrogen distribution system for (cryogenic) electron microscopes
Design details GRE were contracted to design and manufacture a liquid nitrogen (LN2) control and delivery infrastructure with the ability to automatically and simultaneously supply seven Thermofisher Scientific Cryo-EM microscopes with high-quality liquid at stable pressures. These microscopes, each costing around
