I would imagine it would depend on your daily recovery rate.
My personal plan soon when I hopefully can start offering rolling service is to use a 10ton pre chiller to a 2000-5000 gallon reservoir
But I’m only aiming at 800 per day, and don’t want to work long days lol
*tolling service
Damn edit privileges strike again 
Also have been dipping my feet into a recirculating geothermal well based cooling system… not too far off the ground yet tho
Do you still have the pope?
Ima finally finish that wiper build - finally found a talented machinist and welder to work with me on it, if you wanna wait a few weeks we can test drive one for you.
These do not need to cost $30k and I wanna sell parts kits so folks like you can build your own
Im in no rush for anything, i was just curious for future endeavors. Ya let me know your progress
I’ll be resurrecting my thread shortly as soon as I have some progress pics
I was just searching for it
There are some pics of it semi assembled on my Instagram @vene.ficium
Thanks
