IT WORKS!!! IT WORKS!!!
The pump on the well was replaced with a submersible 1.5 HP pump. It now flows plenty of water through 1.25" pipe.
A new well was dug as a return.
The water coming from the well is approx 70 degree. It's not as cold as I can keep a reservoir, but it works.
Because it's not as cold the air coming out of the light chain is much hotter then with the chiller, but it's not coming out hot.
Let me define works... 70% water is going to have trouble keeping the room at 80... it may keep the room at 85. I plan on doing some more testing this week, and I'll post the results.
Running the pump will use less electricity then the chiller, will be much quieter. Sue to a friend of a friend, total cost of new well, pump and piping was 2k quite a bit less then the retail cost of that setup.
Remember there are two water cooled A/C's that give me more cooling power then if I was only running the Iceboxes.
I ran the room for 4 hours and was able to keep the room at 72 with the Air Conditioners on.
I can put my hand on the glass on 11 of the 12 reflectors and feel warm, but not hot. The last one feels hot and gets much cooler a couple inches away from the glass. This baffles me since this light is in the middle of a 4 light chain and the other 3 are fine.
I've had a crazy weekend working on this room and will take a couple days off to catch up on other stuff, so I will post and update soon along with updated picture of the final room configuration.
On a side note: I've been hired to build another room by the same guy. This room will be setup in a trailer. It will be a heath style DWC vert grow in PVC... I'll start a different thread on that one when it starts. probably end of March as he has already bought the trailer and I've got to start a parts and equipment list.

Have seen you over at VG; I'm also going to be building a PVC vert grow within the next couple of months.

Sweet setup. have you given any thought to how the humidity will change your temps.I left my humidifyer on last night and this morning when i came back it went from 78 f to 86 f. no other canges were made in my room other than humidity going from 45% to 72%. Might be something to think about if you lose your a/c

Thanks.
I have. I have two ways of controlling humidity. The A/C's do a wonderful job. Since they are marine units they have a humidity mode that concentrates on pulling humidy instead of just cooling.
The second option is a Hydro innovation water cooled dehumidifier. I have not yet set up a condensation pump and may run this once the pump is setup. I have no need for it now as I can get very low humidity with the A/C's on.
If I was running just the Iceboxes, humidity would be a BIG concern.
Not right now. It pretty much looks the same as I've "wasted" time experimenting.

Its all good brother... I have been draging ass myself as my back is killing me and homework is coming out my ass. Oh well I was once told... it is tired men that rule the world.
So what direction are you heading in??? Marine Boat chillers, water ac cooling units, split ac units... what are your thoughts on some of these?
I am leaning towards the water ac units and the 20 eer split ac units myself for my next project.

Pics from today... excuse the crappy iphone pics. I'm done wasting time playing and experimenting the room will be put to work soon. 
final pics from a design setup, I'll open a journal when I'm ready. This one works...

I think I have a new hero! Lol.
If I had the money I would go all out and do something similar. Nice work. Sub'd and +rep

Nice set-up and alot of work in there. Stephen Bess from HI is a great guy and would be able to answer most problems you run into with all the water cooling set-ups. From what I can tell by the info and picks you posted you are in need of at least 50,000 BTU's of cooling for the 12 lights at 4000/light. Sounds like your getting about 32,000 off the chillers. How many BTU's are the small A/C?. Are they split systems?. I like the split systems as you don't have to vent stinky air and they also remove RH% which is great in your situation. I like that you are scrubbing the room throu your lights in sealed mode. Gives a dual benifit of keeping the glass in the hoods clean and also airmovement for your chill boxes. Some growers don't realize that you can have light loss of 2 to 10% even with just the slightest amount of haze on the hood glass. I like the HI water cooled dehumidifiers and you might want to take a look into them if you start to struggle with RH%. The HI water cooled generators work great as well for your co2 application. Looks good. Hope the room produces lots of medicine(bottom end 13.25lb per cycle/top end 27lb per cycle/averging 20lb per cycle)

Yep... lot's of work. Thanks.
Nope... not using a chiller anymore. Using a well and draining back underground.
26k total BTU if I remember right
No, self contained. Since they are water cooled marine units NOTHING goes outside.
I've got one which looks like it will go into the drying room. The Marine A/C's are doing a great job of dehumidifying right now.
I've got one. Your right works great.
I also bought a propane water heater and played with it... That extra one is now being used in a different setup.
Room should yield minimum 25#'s. 30#'s would be nice... wouldn't be surprised if 33-35 happen.
Target is 30 #'s
