Anyone use a chiller on a skimmer feed line?

[johnnybv]

I am finally going to have to break down and put a chiller on my system. I dont want to add another pump, does anyone have any ideas if cold water through the skimmer will affect the performance?

cold water would be more dense... which I imagine could potentially cause bubbles to stay formed longer... though I'm not a thermodynamics major and I haven't taken a physics class in forever.

You might also want to check what kind of flow the chiller requires because the skimmer feel line might not be enough. I have mine connected directly to the return pump.

Flow rate is exactly what I need, hence the reason I would like to use that existing pump rather than add another. I am looking for some dynamics info on how colder water will affect the skimmer, it is a Deltec with ozone.

I feed 600gph thru my skimmer which just came from my chiller.

Has not appeared to hurt perfomance and don't know if it helps it other than cooling my water.

All of my chillers seem to drop water temp only a few degrees below ambient, maybe 5? So if your system water is 80 and 75 is coming out of your chiller (even 70F if you have a low flowthrough rate) then I don't think you'll see much effect. Foam still forms on the beach just fine when the water is 40F, so I doubt temp has a major impact on skimming.

Sounds good, and chip is doing it with no ill effects, I guess I will give it a try.

John,

 

I have a 1hp chiller running then through a Bubble King 500 and have had no issues compared to where the skimmer ran w/o a chiller prior. This is on a 1300gallon system. Did you buy one of the new Deltecs? Marvin stopped by yesterday and brought out one of the new Deltecs. Very Nice!!

I am not a dynamics expert by no means but other than getting more foam because of the colder water I don't think you should have a problem at all. So a plus in my opinion. Let up know how it goes if you end up connecting it.

this is just on my home system on an ap701, I do not have any of the new ones yet.

way too small a temp change

oh, I thought you were putting this chiller on the store system.

Steve Weast used a ap701 to skim his coldwater reef at 55 F so I think you will be fine.
