Need help setting up a chiller...
- Thread starter kmu
- Start date
Pushing water through it ... but make sure it is atleast pushing the minimum amount of water through the chiller. The chiller will have a flow through range. I dont know what it is for the current 1/15th but the chiller will present some head pressure to the pump and you want to meet atleast the minimum flow that the chiller is designed for.
It should be ok if you only need 100 GPH minium but it isnt a high pressure pump so there will be some loss through the chiller. Also some more head loss if you are pumping the water from the chiller back up to the tank. Just answering your Q and adding something to be aware of. You can always measure flow at the outlet by timing how long it takes to fill a 1 gallon container just to be sure. Should be ok.

You will get a lot of loss though the chiller. I have a 1/10 Current USA chiller. I run a Tunze silence 1073.020 which is 634 gph. After the chiller I'm getting about 180 gph. A significant loss.
Please post the "gph" you get after the chiller. I would be interested in using a Maxi-Jet as well.
One other thing you may want to check is that the FAQ's on Current's site states the 1/15 chiller requires 180 gph not 100gph. I thought mine was 200gph when in fact it's 420 gph....

If the maxijet 1200 doesnt do the job I will just use the stock powerhead which is rated at 396gph so that one should do the job.
ON current usa website they recommend 100gph to 350gph here is a link http://www.current-usa.com/primechillertower.html
Depends on the chiller and the pump.
I use a 1/3 HP Tradewinds, pump is a pressure rated panworld, rated at just under 1100 GPH. Feeds the chiller then a manifold with two valves to a 1" return direct to tank and 3/4" return through a UV sterlizer. About a 4.5 foot rise to the returns over the edge of the tank. Also several 90's and barb fittings as well as an additional valve and union on the output of the pump. I am returning about 900 GPH back to the tank.
Again, this is a pressure rated pump and the tradewinds 1/3 HP chiller obviously uses a larger heat exchanger housing than the smaller chillers so there would be less back pressure there. So again ... depends on how the pump handles the back pressure, the chiller itself and the plumbing.
Like I mentioned, I would measure flow at the outlet back to the tank (or sump) after it is set up and make sure you are getting atleast the minimum flow.

I'd definitely drop them a email about the discrepancy. I am going to do this myself. Here is the link to the FAQ's and it is question 8 I believe. I agree with DarG. You need to test and measure the flow not guess it will be fine.
Which companies make pressure rated pumps? I need one in the 500-600 gph range that doesn't kill the electric bill.

Panworld makes one in that range ... same pumps rebaged as Blueline as well as several other companies.
Probably in the 80 - 90 watt range for that type flow.
Little Giant, Iwaki etc. all make pressure rated as well as circulation pumps in that flow range. All probably close to the same wattage draw.
Im not sure I follow ... what if the pump fills the bucket before the minute is up?
I just time how long it takes to fill a 1 gallon container. 20 seconds for example = 3 gallons per minute = 180 GPH.
For higher flow pumps the 1 gallon container fills fast, in a matter of seconds. You can use any container of known quantity and do the math.

Sorry if I'm not that clear. I have a 5gal. food service bucket. It has gallon and 1/2 gallon graduations on it. I pull the outlet hose off the chiller and insrt it in the bucket, start the pump and in one minute shut the pump off. My pump setting right now fills about 3 1/4 to 3 1/2 gallons of the bucket. So I times that by 60.
3.25x60=195 gph
3.5 x 60 =210 gph
Hope that clarifies my procedure... There are many ways to do this. I guess it just depends on the equipment you have and your level of education. I am definitely not strong at math.

The math part wasnt what I didnt understand. I understand what you are saying now. I was wondering what happens if the pump fills the entire bucket before the minute is up. Your method is fine as long as the pump doesnt provide enough flow to fill the bucket up in under a minute.

In this application it shouldn't fill the bucket. If it did I would just step it down to a 30 sec pump run time and multiply by 120 instead of 60. You could still use 60 and just times that by two and get the same result.
OP did you try the Max-jet yet? I real interested in the out come.

I understand. My pump flows close to 900 GPH after losses, which is why I mentioned the bucket filling before the minute was up.
Only issue is that the water flow would more accurately be measured at the outlet to the tank, not at the chiller. It wouldnt matter much in some applications but if, for example, there is a 4 foot vertical run to the tank after the chiller, there will be additional flow loss.
Thats why I time how long it takes to fill a 1 gallon container. Because I can put the container IN the tank (or sump) with the outlet inside of it. But this wouldnt work in all applications either. So it depends on the setup.

Well I installed the stock solana pump pushing water trough the chiller and into the tank on the stock output, it still pushes more water than the maxijet 900 I had in there before the chiller install.
