DNO, ATEX, DSEAR & WIMES approved sealing
In highly regulated sectors, sealing systems must do more than protect against fire, water or gas – they must also meet stringent industry standards for safety and compliance.
From substations and hazardous areas to water industry assets, CSD provides sealing solutions approved by DNOs and compliant with ATEX, DSEAR and WIMES requirements.
Your Challenges
- Strict compliance requirements in hazardous and safety-critical environments
- Risk of ignition or explosion from gas leaks in ATEX and DSEAR zones
- Need for certified solutions trusted by Distribution Network Operators (DNOs)
- Long-term reliability required in regulated water industry infrastructure
Our Solutions
“CSD Technical Services delivered the water, and gastight sealing works to a high standard across our control room and DNO substation. Their support contributed effectively to our wider climate action plan, including the installation of a new solar farm and battery storage system. We were very satisfied with the work and will be considering CSD for future projects.”
