Thanks, Jessica. It seems like clean agent options have narrowed a great deal, some phasing out due to global warming impact and others because they contain PFAS. Yes, I'm interested in your decision matrix, if you don't mind sharing.
Since the particular space we're addressing was outfitted for Halon, it should be viable for an inert gas system and I think that's probably what I'll recommend. But I'm still interested in examples from the field, whether they reinforce the inert gas direction or suggest other possibilities. It's also possible that we'll discover some obstacle for inert gas (cost, engineering limitations, ...), so it's best to have some backup strategies in mind.

Hey Andy,
We installed a clean agent system during our recent renovation (2017 project start, 2020-ish system install). The clean agent we went with (Novec 1230) was partially chosen because it was not scheduled for phasedown or phase-out, had a smaller climate impact, and the infrastructure would work with our somewhat challenging physical space. But your question led me to poke around and now I see that 3M is getting out of Novec 1230 manufacturing by 2025... so I guess I need to look more into what that means for us in terms of future suppliers.
If you're interested, we have a decision matrix I can share. We were considering some different approaches, but ultimately the variances required and the infrastructure impacts left us with limited reasonable options.
