Our fabrication team have been inundated with cryogenic systems over the last few weeks.

Pictured here is a vapourising (or vaporising, depending on where you are in the world!) water bath that will be cut-in to a client's system to provide a stable and continuous flow of gaseous nitrogen from an LN2 spur line.

If you require something similar, please do get in touch, as we'd love to help.

The final touches are being made here, to a proportional LN2 supply for a quad-crystal monochromator.

Combining flow monitoring with proportional control, plus feedback to the client's control/monitoring electronics, this system will allow the end user to moderate the amount of sub-cooled LN2 going into the crystal cooling system (as the secondary crystals require less cooling) for efficiency and stability.

If you have a requirement for a bespoke cryogenic cooling system, please do get in touch, as we don't just make vacuum jacketed transfer lines!

Deionised water treatment and chiller, all in one unit - no problem!

The picture in this post is of a DI chiller for lab use (hence the stainless teel case). The chiller is part of GRE's Fortis range, which comprises standard and multi-function machines (heater/chillers, air/water, water/water and DI/Ultra-pure water chillers) that can be tailored for customer's exact requirements.

If you have a use for similar equipment, and are struggling to find a single solution, please get in touch as we would love to hear from you.

Recently David, on e of our Engineers, went to France to carry out a detailed site survey for an installation of a containerised plant room incorporating GRE's refrigeration technology.

Early engagement on site is essential to successful project delivery, allowing our engineers to assess access, plant positioning, service routes and installation requirements before work begins.

By investing time in the planning stage, we can ensure projects are delivered safely, efficiently and to the high standards our clients expect.

Lille is a beautiful and charming city full of kind and welcoming people while David was there he took the time to view some of the amazing architecture and of course the fancy cuisine!

We look forward to bringing this project to life in the coming months.

You know when you're in Devon, when : one of the GRE welding technicians drives his tractor in to work!

Another week, another LN2 cryostat build!

This vacuum-insulated cryostat / valve box has been designed to incorporate connectors, valves and relief devices needed to throttle flow on a dual-circuit liquid nitrogen supply system.

Using our 'go to' cryogenic valves by , supplied by , the cryostat will form part of a wider vacuum-jacketed pipe system for cooling a monochromator, at the Diamond Light Source facility in Oxford.

Designed around a LIDAR scan of the facility, the 3D modelled lines are 'dropped' into their virtual home to check for fit, prior to being manufactured. Once manufactured and conditioned, the whole system will be transported to DLS, where it will be fitted, tested and certified by our experienced technicians.

Every once in a while, we get to help a worthy local organisation with some funding/equipment/knowhow.

Yesterday was such a day, when we were treated a guided tour of one of the UK's most fabulous working factory museums - Coldharbour Mill, in Uffculme, Devon.

Purchased by Fox Brothers (famed for making 'Puttees', for military uniforms), in the 1700's, the woolen mill was operational until the 1980's, relying on water (from it's own mill wheel), steam (from its own 'Lancashire' boilers) and electricity (from it own coal-gas electricity plant) over the years before the UK electricity grid was born.

GRE was recently able to support the renovation of a very rare 'combing' machine (of which there are, allegedly only three still in existence) and the mill, very kindly, allowed us to put a a small plaque in machine room.

Run almost entirely by volunteers and charitable contributions, the museum is a true testament to the passion for the preservation of the UK's industrial/engineering past.

Having had the grand tour (for the first time since he visited during a Primary School visit around 40 years ago!), GRE's Commercial Director Steve Alford, would thoroughly recommend a visit to anyone heading South down the M5 for the summer!

Pictured here, is another bespoke system design/build for a client by GRE.

This one is a little special in that it collects, pumps and purifies/scrubs vapour created by the clients process, then re-liquefies it, before decanting it back for re-use - all in one system using one simple controller.

Currently in final tweaking/testing, the system should be coming together in next few weeks, before being put to use by a collaboration between a prestigious UK and US university.
