City
City - Global Engineering Solutions
Smart Engineering Solutions for the Cities of Tomorrow
As we move to smart cities with everything from traffic management to air quality systems being connected, here at Barnbrook we are driving this change.
With changes in green energy and the move to Hydrogen we are using our knowledge from the Aerospace market to develop systems that can withstand the challenges this energy brings like high pressures and the nature of Hydrogen’.
As cities around the globe make this change we here at Barnbrook work with our local partners to support and drive innovation in this movement. With over 50 years of developing systems for Rail, Aero and Marine and Defence, we are now also focusing on the segment we call City, focusing on Fire Suppression, Energy Storage, Energy Harvesting and Air Quality through sensing technology.

Our Capabilities Include:
Fire Suppression
Keeping people and assets safe is our core focus. With connected systems the ability to be notified and take action has never been easier. We have been supplying this industry for many years with our actuators and we are now developing and launching the next generation of Fire Systems.
Energy Storage and Harvesting
With the growth in Ai and Data Centres the need to conserve power has never been more relevant. We have developed products that can support this growth by reducing the loss of energy through dated systems and approaches.
Air Quality
Knowing the quality of our city air has become a important indicator. We have systems to monitor and report on air quality and the relevant actions can be taken.
Connected Devices
Many connected solutions on the market are power hungry and send data that is often not relevant. With BlueCube our customers have the ability to have data that really makes a difference in better maintenance, cost savings or improved efficiency.
As we move to greener cities Barnbrook is a the forefront of supporting this change. Barnbrook combines innovation with a hands-on approach to meet the evolving needs of the City sector.
