FM-200 Cylinder Testing
Periodic inspection, hydrostatic testing, servicing and agent refilling of FM-200 (HFC-227ea) fire suppression cylinders, carried out in Kilmallock. Until now, cylinders like these had to leave the country for periodic testing. We are the only facility in Ireland that is ISO 18119, TPED and ADR compliant and equipped to handle them.
What the service covers
FM-200 systems protect server rooms, data centres, archives, switch rooms and plant rooms. When their cylinders fall due for periodic inspection, the system is only protected once they are tested, serviced and back in place.
- Periodic inspection and hydrostatic testing of FM-200 suppression system cylinders to ISO 18119 and TPED.
- Valve and actuator servicing so the cylinder goes back into the system ready to operate.
- Agent refilling — cylinders recharged with the correct suppression agent and weight after testing or a discharge.
- ADR-compliant collection and return of high-pressure and agent-filled cylinders.
- Decommissioning and documented disposal when a system is replaced or a building is stripped out — see cylinder disposal.
How testing works
Every cylinder that comes through our doors goes through the same disciplined process, regardless of what it held or who it belongs to.
- External examination — checking the cylinder shell for corrosion, dents, gouges, fire damage and any deformation that would affect safe use.
- Internal examination — inspecting the internal surface for corrosion, pitting or contamination once the valve is removed.
- Hydrostatic test — pressurising the cylinder with water to a set test pressure to confirm it holds pressure safely and hasn't stretched beyond an acceptable limit.
- Valve and actuator servicing — checking the valve and any pressure-relief device, and servicing the actuator so the cylinder goes back into the system ready to operate.
- Stamping & certification — cylinders that pass are stamped with the test date and our identification mark, and issued with certification paperwork for your records.
Cylinders that fail are held separately and reported back to you, with an explanation of why, rather than being quietly returned untested.
Part of our fire suppression service
FM-200 is one of the suppression agents we handle, alongside FM-200, Novec 1230, inert gas (IG-541, IG-55 and IG-100) and CO2 total-flooding systems. See the full picture on our fire protection page, or read more about cylinder testing & recertification.
