It’s been quite a journey so far. Put together a system in a 8x4 tent.
Everything has been insulated and wrapped with mylar emergency blankets. I decided to build a control res, refill res with valves for either one to use the chiller.
A RO system will be installed which will go to the refill reservoir in the back. I am putting in a float valve in the refill res so it gets filled in between change outs without my doing anything. (That is the plan anyway!)
When it is time to change water, I will pump out old water while chilling the water in the refill res. Then a line from the control res goes into the tent. Gets a manifold in the center to split left and right. Another manifold feeds each hydro station.
Large air pump in the back of the tent.
Thanks much TDubWilly for your help earlier getting me started.
