I completely lost my senses and decided to try to do something I have not seen yet. I made an offer on this beauty and it was accepted. I also made an offer on a batch of Tescom 0-30 psi manifold mount regulators (also accepted). Guess I am committed now. The idea is to make an all in one regulator assembly that will allow precise control of a set of 4 secondary regulators with solenoids, gauges, needle valves, and flow meters. My hope is that I can use them for whatever type of CO2 injection method I choose and it will satisfy my rapidly growing case of MTS (at least on the CO2 front). Hopefully I do not go past 4 tanks...
My plan is to make a 1-1/2 x 1-1/2 x 12 inch aluminum block manifold that will be drilled and tapped to provide the flow routes and attachment points for all the other components. I can trim it to the length that I really need. I plan to use a high pressure air hose rated at 4500 psi between the tank and the primary regulator assembly.
The pretty little ball in the photo is a Swagelok high flow regulator that is pre-set to 60 psi which it will hold between 80 and 1000 psi input pressure (Yeah, I will have to be extra careful to not put a hot or overfilled tank on it). I will be reversing the direction of the regulator to put the output on the left. The next piece is a distribution manifold which will distribute that pressure to my manifold block providing 4 separate tubes to my secondary assembly. The third item on the top right is a pressure switch that I will connect to a DIY alarm (possibly a dismantled smoke detector or maybe something prettier) to alert me when my CO2 tank runs dry. Definitely will need a disable switch as I would hate to have to listen to an alarm till I could swap tanks. I could also hook it to a indicator light to show when it has pressure because it has both NO and NC outputs, but I think it would be unnecessary. No alarm = pressure. The secondary regulators are rated up to 150 psi with an output of 0-30 psi. I plan to run the power supplies to the solenoids from a smart outlet strip that will give me wifi control of the durations.
Does anyone see a problem with using aluminum for the manifold? The CO2 should be completely inert as it does not become acidic until it combines with water.
I know... I have gone completely insane...
