Hydrogen sulphide and related sulphide gases from drain biofilm are a recognised contributor to creep corrosion on gold contacts and silver solder joints, and the damage often shows up months after the exposure starts. Green Drain™ is a passive one-way insert that keeps sewer gas in the pipe, removing one route by which those gases reach the room air.
ASHRAE TC9.9 guidance and Telcordia GR-63-CORE both address corrosive gases in equipment spaces. Neither says anything about floor drains, but a dry trap is one of the simpler ways for sulphide gases to get into a building, and it is easy to fix.
ASHRAE TC9.9 guidance and Telcordia GR-63-CORE address the equipment environment, the Uptime Institute rates resilience from Tier I to Tier IV, and ANSI/TIA-942 covers infrastructure and environmental controls. None of these standards addresses floor drain trap seals, so drain hygiene is a housekeeping matter rather than a compliance one. Dublin remains one of Europe's largest data centre clusters.
Statistical data taken from official Irish and EU sources: Central Statistics Office Ireland (cso.ie), Health Service Executive (hse.ie), Fáilte Ireland (failteireland.ie), Bord Bia (bordbia.ie), IDA Ireland (idaireland.com), Health Products Regulatory Authority (hpra.ie). Regulatory framework: EUR-Lex for EU directives — EU 2017/745 (MDR), EC 852/2004 (food hygiene, HACCP), EU 1935/2004 and EU 10/2011 (food contact materials), EU 528/2012 (BPR), EU 2014/34 (ATEX). Standards: EN 1253-1 (floor P-traps, water seal ≥50 mm), EN 1253 Parts 6/7/8 (gullies with a water seal below 50 mm, with mechanical closure, and combined types; 2023 editions), HACCP International RG-04, ASSE 1072-2020, NSF/ANSI 2, HSE AMRIC (Antimicrobial Resistance and Infection Control) guidance. Notes on status: Green Drain™ is an insert fitted into an existing drain, not a factory-made gully, so it is compatible with drains built to EN 1253 rather than certified to it; it is classified Class I under EU MDR 2017/745 with conformity self-declared under Annex IV (the manufacturer is registered in EUDAMED under SRN DK-MF-000052289 — there is no third-party MDR certificate), it does not prevent, diagnose or treat disease and supplements rather than replaces infection prevention and control protocols; NSF/ANSI 2 evidence is a listing (C0571796); HACCP International RG-04 is a private certification programme and it remains for the operator to decide whether to include the product in their own HACCP plan.

Nothing gets improvised in a data centre. Everything goes through formal change management and an agreed maintenance window. Fitting out a typical washroom takes about 30 minutes.
We survey the drainage layout and note where traps sit in relation to the machine hall.
One washroom and corridor over 30 days, with H₂S and SO₂ readings before and after.
The change is raised formally and added to the maintenance schedule.
Fitted during agreed maintenance windows, roughly 30 minutes per washroom.
Irish data centres are typically built to Tier II–IV resilience levels. Staff washrooms use conventional DN50 drains, while mechanical zones, CRAC rooms and UPS rooms are heavier duty. The silicone insert is rated from −40 °C to +100 °C, so hot aisles present no problem.
We supply the technical documentation and the ASSE 1072-2020 test report, and confirm compatibility with drains built to EN 1253. Uptime Institute tier certification does not cover floor drains, so this is supporting evidence for your own corrosive-gas risk assessment rather than a compliance requirement.
Yes. Take H₂S, SO₂ and CH₄ readings at chosen points before installation and again afterwards, and compare.
Green Drain™ works best alongside GD Uri-Tabs™ for urinals and GreenSwirl™ for clearing biofilm and slow drains.
Patented silicone insert for floor drains in plant rooms and washrooms. It sits inside the existing drain and does not affect airflow or the temperature profile.
Bio-enzymatic urinal tablets for staff washrooms, lasting 30–45 days each. No volatile chemicals to be drawn into the HVAC system.
Breaks down biofilm in the drains serving office and support areas. No harsh chemicals, and biofilm is where the sulphide gases are generated in the first place.
We come to the site, map the drains, and provide a written recommendation — no cost, no obligation.
