water chiller help????

so heres the deal I'm looking to get a chiller to cool a G res. the res is hooked up to a water cooled co2 gen. The temps of the water go from about 65 to 90 in one light cycle, then cool back to close to 65 again. but with the summer heat coming up its going to be harder to keep cooled. What i need to know is if a 1/10hp chiller will be able to drop the temp to 60 or so in a 12 hour dark period with room temps of 68? Also how much heat/ humidity do these put off? is it worth plumbing it so it outside the grow or is it no big deal?

I was planning to run the co2 and chiller on a flip flop so co2 is on with light and chiller in the dark. It seems like awaste to run a chill and the co2 gen at the same time as one heats the water fighting the other trying to chill it. I'm totally open to suggestion so holla it me

My little ecoplus 1/10hp chiller works very well, I was able to run a chiller inside
my grow room and cool roughly 20g of water to a cool and consistent 60* without
really breaking a sweat and running 24/7. I imagine with a 1g bucket and a 1/10
you'd be fine to run it in the room, but I like to run mine outside as it really makes
things easy.

i have 4 bottles of frozen water and I put 1 or 2 into my res every light cycle and never had a problem, ya its ghetto but its cheap and easy

That works because the reservoir is a bit more flexible with temps. He is needing it for a water cooled
co2 generator which will need to be consistent in the temperatures it produces because the co2 gen is
dependent upon it. There's simply too much room for error in using frozen water bottles for this application.

oops i see it say a g res. its actually a 55g do you still think a 1/10 will be enough? I probably will place it outside the room too.

I would get the biggest one you can afford. I think the prices for the small 1/10 aren't much cheaper than the 1/4 hp. there's a guy on ebay that sells a converted 1/2 hp window ac for about 400.00 that has great reviews. going bigger will give you options in the future. Water cooling lights or just removing heat from simple things like your dehuey. To go cheap, I ran my 2000 watts off of an AC with the condensor coil hanging in the water. All of these units are rated with no load on them. Being able to pull 300 gallons down 20 degrees from ambient is different than pulling 100 gallons of water down 20 degrees that is absorbing 12000btu of heat every 15 minutes.

what are you expecting the ambient temps that your 55g rez is going to be subject to this summer? I don't see 110-120 water towards the end of your cycle as being a problem. As long as your pump can take the heat. It will still remove a ton of heat from your room with 110 degree water. Maybe go 100 gallons. A fan blowing over the top of your rez, not having a lid on it can help it dissipate heat and lowered mine 5 degrees. Lost about 1 gallon a day though.

I can run my fresca sol water cooled lights with 110 degree water and barely tell the difference. They still remove 85-90% of the heat in the room. You may just want to see how it develops.

thanks budley, i think i'm going to try to up grade the Ac instead nowi have a 5000 btu window unit but might replace it with a 12k dual hose portable if i can find out if it work w/ co2, dont want to remove all the co2 from the room with the ac. by the way i have a 3000 watt setup

I was just gonna say, I was about to pick up a 5000btu AC unit for my closets lower half, where the dwc waters are - a/c removes CO2 from the air?

Air conditioning or carbon scrubbers do not remove Co2 from the air. A portable AC with a single hose will, but a dual hose theoretically should not. A window unit doesn't remove co2 but it isn't airtight and will leak a little. Your sealed room should not have any positive pressure in it to push the air out.
