FM200 (HFC227ea), Novec 1230, FE13
These gases are stored as a liquid, with nitrogen used to pressurise it. When released the FM200 has a chemical reaction with the fire and extinguishes it.
- Cost effective as the footprint of the cylinder is small – this is an advantage for data centres that charge out their rack space, and so are looking for minimal space requirements of their data room. This enables them to gain more revenue by having more floor space for servers. IG 55, 01 etc. do take up more floor space but the cylinders can be put remotely from the room.
- Stored as a liquid so takes up less space.
- Well known brand – FM200 is a brand name, the agent is a chemical called HFC227ea.
- Easy to install because the cylinder is usually in the same room. Sometimes just a standpipe on top of the cylinder is required.
- No reduction of oxygen so it’s safe for humans on discharge.
- FM200 does not travel well (because of the pressure) or is rarely cost effective over inert gases if it’s a large room or the gas requires diverting to different areas/rooms. Cylinders must be stored as close to the application as possible.
- Some companies are saying it’s a potential future banned gas as it’s a hydro fluoride chloride (HFC) – we have had clients who insist on an inert gas because of this. In fact Dupont, who manufacture FM200, are actively giving guarantees to replace the gas (less installation) if it gets banned in the next 20 years.
- Pipe work design has to be accurate. A slight change of pipe run in distance or length can mean the design calculations have to be changed and a potential major costs change. Because of this, don’t use FM200 if you cannot guarantee the pipe run design and installation will remain the same.
