The Co-operative Bank has recently taken delivery of the world’s largest compressed air UPS system to protect its data processing facility in Stockport, Greater Manchester.
Integral to the new solution is Hale Hamilton’s valve manifold solution, which is used as part of Energetix Air-DRUPS (compressed air, diesel, rotary UPS) system.
At the heart of the valve specialist’s manifold solution is a proportionally controlled cartridge pressure regulator and a high speed solenoid valve.
James Derby, general manager at Energetix commented on the speed and reliability of the Hale Hamilton solenoid valve, explaining that both “contribute significantly” to the success of the product.
“With total confidence, and within no more than a few tens of milliseconds, the scroll expander can be supplying critical power to the data centre load,” he added.
Ian Davies, sales director at Hale Hamilton Valves Ltd said the development of the product had been a few years in the making, in order to meet the demanding technical and commercial constraints applied.
“We have been working with the Energetix team since 2007 to create a solution that provides a proportionally controlled flow of gas to the scroll expander depending on the demand on the system,” he explained.
Part of the challenge was to ensure that the pneumatic control module was compact, with minimal connections. This ensured that the unit could be installed very close to the scroll expander, and that any potential leak points were kept to a minimum.
Known for their commitment to good environmental practices, the Co-operative wanted to install a highly efficient system that would operate reliably, without the need to run costly air conditioning.
Energetix’s Air-DRUPS solution combines high-efficient double conversion UPS technology with energy storage in the form of compressed air. This allows the system to provide maximum efficiency at just half load, while the compressed air batteries consume only a very small amount of power during standby.

Nitrogen portable charging unit launched for non-military sector
Hale Hamilton’s hugely successful and highly acclaimed military nitrogen portable charging unit has now been launched into the non-military sector. The portable Nitrogen 2 Go (N2GO) is now available in the civilian market and is expected to prove every bit as successful as the military version.
First used by the UK Royal Air Force, the portable gaseous ground support equipment is now in daily use with foreign military forces in countries far and wide, from Australia to India, Malaysia and Singapore.
The product was originally developed in the mid-2000s as a direct response to a competitive tender from the UK Ministry of Defence Air Support IPT. Hale Hamilton developed a range of all-new portable nitrogen and oxygen charging units, or PCUs, to replace the Hale Hamilton ‘walk around’ kits that were in service at the time.
The MoD determined that Hale Hamilton’s new PCUs best met the pre-determined criteria which included low weight, ease of portability and the provision of both high and low pressure nitrogen outputs. The company supplied 1000 PCUs which remain in service with the UK military across the globe today backed with a guarantee of ongoing, through-life suppor, that reflects the products quality and integrity, the PCU’s.
As a result of the continued success, there had been an increasing demand for a civilian, or non-military, product equivalent. Hale Hamilton has therefore developed the nitrogen PCU and its variants to meet the operation and maintenance needs for most commercial airliners, business jets and helicopters. Now available with the option of wheels, extending handle and a removable lid, Hale Hamilton’s N2 Go range of portable nitrogen charging units leads the field in portable gaseous ground support equipment today.
Trevor Bignold, Hale Hamilton’s sales manager, is delighted with the successful development of the company’s latest product:
“It is easy to carry our PCU out on to the flight line by hand or in a van and with 300bar nitrogen you can top up tyre pressures, charge a strut or charge door accumulators. It can also be flown fully-charged, subject to our customer having approval. It really is a handy source of nitrogen on the go. We now call it N2 Go!”
