the potato replaces the apple. duh.:bum: :rollface:


try the hottest water you can find that wont break your fractionator. i guarantee it is better than ice. :smokin:

If only I had my time machine! My wife and I have already commited to each other that once we retire, we are going to become MAJOR 'heads again.
 
So what I was thinking about along the problems is the following, using one pump to push water through a series of shorter tubes one next to another. I was thinking that 4 x 4" pvc at 3' tall under a tank would be enough, the top of the "Bong" can be easily vented in my situation because it sits in front of a window.

I keep looking at the Deltec sco cooler, and the way that they cool water is the same but is more horizontal, not vertical.

DMbillies, I too though about a separate freshwater running system, but i'm not really sure that even with a good heat exchange coil that it will work that good. I am presently using fans, and evaporate a lot of water, I just want it to work better when summer rolls in.

"man did I get the wrong idea"

Me too!

I love the idea of using this to cool a tank. I think it is doable with some large diameter PVC or ABS, a computer fan & a tiny ( high pressure ) pump.

I'll bet you could eliminate a chiller on small systems for minimal cost.

The things I'd worry about in our systems:

1 - Youd have major salt creep, so it better be easy to flush or clean.

2 - You would massively increase your evaporation so be prepared to need an ATO




As for the 'i've seen some pretty intricate umm... "devices"'

Dont ask what I can make from:

24 inch tall rubber highway Hazard cone.
Bathtub full of hot water
A Potato
An aluminum tube & Some surgical tubing
.......

Lets just say Ive done a little foam fractination experimentation.

Cypress Hill anyone? :bum:


If you plumbed off the overflow of your main tank and built the bong water tower there you would have close to 4 feet before the sump(depends on tank setup). Since this is going to dump in the sump, there is no need for an extra pump that you are not currently using. Your return pump will return the water to the main display tank. No extra power head to add heat.

Definitely true depending on your set-up (i.e., easier to do if your overflow is out the back of the tank and high up--I wouldn't have this option since mine come out of the bottom). You could also get around needing another pump by splitting the output of the return pump, but of course you'd be pushing less water through the sump that way. Still these solutions don't get around the evaporation of tank water problem... which I see as a MAJOR one.


Some conservative figures:

If RO/DI rejection is 3 to 1 and you're evaporating an additional 10 gallons per week as a result of running your chiller, then you are burning an extra 40 gallons of water per week (30 gallons going straight down the drain). That's means your RO/DI is treating an additional 2,080 gallons of water per year and 1,560 gallons of water is going straight down the drain. This is perhaps better than the amount of electricity being used by a standard chiller, but I would still hesitate to call that "eco-friendly" or a very efficient use of water (which has been very scarce in the South over the past few summers). These figures get dramatically worse depending on your RO rejection rate and size/efficiency of evaporation in your chiller...


I'm mostly just playing devil's advocate here because I've really thought hard about doing something like this. If you're not concerned with the evap and can build one pretty cheap, by all means go for it. It will certainly work... and I'd love to see pictures of a build.
 
i tried a mod on the idea but i dont think its nearly as effective.
