I'm using an mkiii and wanted to try out running propane in my machine. I use an appion g5 twin, and a freezer setup cooling my supply tank. My understanding is that I'll need an after cooler so my pressure doesn't get too high from the warm propane recovering. I know propane operates at a higher pressure and just wanted to be safe before attempting this.

What type of equipment upgrades needed for propane blends?

As FS notes, the 6" clamp needs to be switched to an SSH high pressure clamp.
You will need an after cooler to cool the pump discharge. 1/2" X 50' stainless coil should do it.

Thank you kind sirs.
I already use high pressure clamps on my machine with ptfe screened gaskets and tuff steel gaskets. So it looks like i just meed that aftercooler. Thank alot guys. Any additions that could optimize things that I wouldn't see until I start running the blend?

I don't know when or where you put together your MarkIII, but a lot of early adopters found out that their various valves were not performing well at extreme low temps. Perhaps research the suitability of your current provisioning because there is nothing quite as anus clenching as weeping valves mid-process...

Is it possible to run a blend passively? Would I need to use the coil on recovery?

If you use pure propane, then you're going to hit 150psi at 80F ambient. That's within the rating, but way too much for comfort.
I use 70 isobutane, 30 propane from Ecogreen. I look at the chart and see where the mix is at 0psi, and what pressure it will be at your ambient temperature. If you feel OK with that range of pressures, the mix will work. For me, 0psi comes at -10F, and there is 40psi at room temp. I'll never ever be working at 90F, so the max I'll see is 60psi. That feels fully safe to me, and 40psi is enough for any liquid wash or gas push.

Who makes the best propane extraction system?
So with a max recovery temp of 80-85F and a 70/30 propane/butane mix would the standard condensing coil from Terpp ( https://terppextractors.com/collections/accessories/products/stainlesscoil ) be acceptable, or would we need a larger after cooler?
