1 chiller, multiple systems

[Mr Blah]

Is it possible to chill 2 or more systems with one 1/2hp chiller?
The only way I can think of doing it is have a separate bucket with multiple pumps supplying each epicenter via copper pipe.
I would like to go directly out of the chiller into a water pump then a manifold to each systems epicenter then return back to the chiller from another manifold.
Can someone help me wrap my brain around this?

Not building till next summer just anticipating heat.

chill a big outer rez full of bleach water or antifreeze and put your actual rezes in it.

Use some 12" stainless coils about 4 or 5 loops per coil and have a seperate reservoir probably 50gallons or so and run one large pump probably 1000+ gpm and run the chilled rez water thru both coils (one in each nute rez) and back to your chilled rez. That way the chilled water never comes in contact with your nute water.

You can add a manifold for supply and return lines and add ball valves to regulate the temps.

Thatd a good way to use one larger chiller for lots of things that require it.

Thanks guys. That's what I thought would have to happen dealing with multiple epicenters.

What green said. I have 2 reservoirs, a CO2 generator, and an 8" can fan pulling through a large phresh filter and pushing through an icebox. These are all tied in through PVC and tubing going to a 50gallon drum. They are all running through a 900 gph pump going to a 1hp chiller.

Works great. Without a dehumidifier the PVC and rubber hose in the room is so cold that the condensation is dripping off of it.

So your 1hp is chilling 2 rez's, Co2 gen and an icebox?
So the 50 gal drum has a pump that is a pumping through a closed circuit to all mentioned above?
What is the setting on the chiller/water temp?

The greatest thing i have ever done in my grow. i produce a whole lb a 1000 that way.

Great idea but I got 2 27 gal rez's/epicenters. Would need a pretty large tote for both to fit into.

Yes, it is chilling all of that. There are multiple pumps. One sends water to the icebox and also some cooling coils in the rezzes (make sure you use stainless steel!). The other goes to the Co2 generator. The power to the waterpump for the CO2 generator goes to my environment controller. So when CO2ppm goes too low, it turns the water pump on which in turn kicks the CO2 generator on. The pump providing water to the rezzes and the icebox stays on 24 hours. I have it set for 62 deg F. This keeps my room at a respectable temperature as well as the reservoirs. Be sure to send the water to the icebox first though. I kept my room under 85 deg and the reservoirs under 70 deg all summer lon. Now that it has cooled off, I have not changed the temp setting on my chiller but I noticed that it cycles on and off less often.

For water distribution I used 1/2" and 3/4" PVC with nipples on the end to switch over to flexible hoses to make the connection to the icebox, generator, and coils.
