As i hope you know, as you run your butane it will be picking up water from the material and air inside the machine thats doesnt get purged. Your purge method will gets most of the air out but id still say 30% is air. Depending on where you're running(outside) that could be a lot of moisture being introduced to the machine. What do you recommend for removing this moisture from that top storage tank? It doesn't look like it opens so cleaning it looks very difficult. This is a problem ALL closed loop systems are facing, as your recycle your butane it will pick up any water it can along the way. I dont see a place for filter dryers
I see that you pressure tested your sight glass with room temp water, have you looked at how much the glass is weakened when you have -30f butane in it?
What material are your seals? Are the rated for -30f extraction?
Why didnt you choose high pressure clamps for your device?
So far i haven't seen you mention anything about removing the rust inhibitors and stuff(mystery oil) while loading the machine, I know your machine can, you should probably instruct your users how.
Since sub zero butane is being used i would advise your clients to not soak their material using the sightglass as the hydraulic pressure butane creates rises very quick.
I havent seen very clearly how much butane to load in the system. How much do you recommend?
