Updated recommendations from the International Maritime Organization (IMO), effective 3rd December 2025, place greater emphasis on carbon dioxide (COโ) as a critical atmospheric hazard during enclosed space entry.
Why does this matter?
Many standard 4-gas detectors monitor oxygen, flammable gases and common toxic gases, but don't detect COโ. Without COโ monitoring, crews may be making entry decisions without a complete picture of the atmosphere. COโ can build up unnoticed in cargo holds, ballast tanks, void spaces and connected compartments, creating a significant risk for personnel entering these areas.
Our Gas-Pro can be configured with COโ sensing, helping support safer, more informed and compliant enclosed space entry procedures in demanding marine environments.
If you haven't reviewed your gas detection capability recently, now is a good time to check it aligns with the latest guidance. Get in contact to discuss more: https://bit.ly/4fKYZI4

We're pleased to share for the second year running, Crowcon has had BESS products shortlisted, this year for the Innovation Award at Solar & Storage Live, recognising BESafe for its innovative approach to gas detection for battery energy storage systems (BESS) and its contribution to protecting high-risk energy storage spaces as the sector scales up.
โWeโre pleased to see BESafe has been shortlisted for the Innovation Award. As battery storage becomes central to the energy transition, protecting these high-risk, compact spaces demands detection technology thatโs fast, reliable and easy to maintain. This shortlisting reflects the work weโve put into engineering a solution built specifically for the demands of BESS sites.โ
The winner will be announced at a ceremony on 22nd September 2026 in Birmingham. Read the full press release here: https://eu1.hubs.ly/H0x3QRz0
Last week, colleagues from across Crowcon came together at The Cosener's House for our annual Summer Party.
It was an opportunity to step away from the day-to-day, reconnect with colleagues and celebrate what we've achieved together over the past year. Events like these remind us that while innovation drives our business, it's our people who make it possible.
Thank you to everyone who helped organise the day, and to every member of the team who made it such an enjoyable event.

โ MK Test
โ Halma
After weeks on the road and more than 1,100 miles cycled, the finish line is now within touching distance. What began with visits to Crowcon and Navtech Radar is set to come full circle as Andy aims to complete his challenge to cycle to every UK based Halma plc company.
This remarkable challenge marks Andy's 28 years with Crowcon while raising funds for Sue Ryder in memory of his dear friend, Andy Earnshaw.
As Andy prepares for the final stretch, we'd like to thank everyone who has followed the journey and supported this fantastic cause. Donations remain open for anyone wishing to support Andy and Sue Ryder: https://eu1.hubs.ly/H0x1KcD0
