Where do you connect to the chiller?

[7thheaven]

Hi all~

Where do you connect to the chiller?


1. overflow inlet-> chiller-> sump
2. Return pump-> chiller-> outlet to main tank
3. both are OK...

Currently I connect like #1 but I am not sure it is effective..
and wonder the detrius from overflow can be filed(?) in chiller...
cause maybe water speed is not enough...

which # is correct?

[fkadir]

Im doing #2 I prefer to feed the chiller with Skimmed water instead of 'dirty' water straight from the overflow. That should go to the skimmer directly before anything else.

Thanks Farish~!

Is it possible to file the detritus in chiller in case of #1?

i go by option 1.. if you know your main to sump turn over rate is high...

and I dont believe feed the chiller with Skimmed water, how can you be 100% sure the water you feeding to the chiller is just purely skimmed water? and not mix with overflow?

unless u go tell me u got 2 sump where the skimmed water go to 1 sump and chiller will be feeding from that sump. But by doing this issit mean your feeding rate for your skimmer in very high flow and thus affect the dwell time

so sorry keigo..I do not understand what you said..
My skimmer do not need feed pump. (schuran 150) It is in sump.
the water through chiller fall in the sump. and my skimmer do the job with water in sump...

When water in overflow inlet go to chiller, No feed pump, just gravity...

I wanna know you can understand my bad x 100 english... :playboy:

NOT file===> piled up...

Vince, you can use your overflow and that's nice because you don't add another pump/heat. But, you need to be sure you are putting the appropriate/correct amount of water through the chiller. If you use a pump to feed the chiller then you know how much water is going through the chiller. Both have their benefits and drawbacks.

One the reasons an overflow is not recommended specifically for a chiller is that if "something" gets into the chiller and gets stuck you'll never know. It's not like feeding a skimmer or something that you can see the inside of.

The head pressure loss through a skimmer is about equal to an elbow of whatever you've gotta restrict the plumbing to. I can tell you I get very little apparent head pressure loss running through my arctica 1/2 hp using 1" plumbing with my RD. I've got the RD hooked to a 1.5" cross with the 3 outlets then going down to 1" and the thing RIPS.

Thanks....Could you tell me the proper water flow through the chiller (200watt 1/4HP)?

[moonpod]

the manufacturer should have recommended flow rates.

Ideally it's tank-chiller-tank so you can leave your chiller running when you take your sump offline for maintenance (or flooding ), but that's not always practical.

A little chiller like that probably doesn't need much more than 1000lph so a small Eheim pump will do.

[keigo]

well depend on how you set it up and you have to factor in head loss too....

Vince, you should be doing at least 1/2 yearly cleaning of the chiller in both #1 and #2. Do a backflushing for the chiller too if possible.

i have mine taking water from the sump area near my skimmer and putting it back near my return pump

How about this plan?

sump-> RD pump-> use T outlet like this ㅓ ->ball balve-> left plumbing go to chiller
-> upper plumbing goes to main tank.

In Left plumbing(chillerside),
Left Plumbing-> chiller inlet-> chiller outlet-> sump again...

Is it not efficient? I don't want to add feed pump for chiller...

What about your opinion...

my chiller,Arctica 1/4hp, is needed flow rate more than 480(min max is 1920gph)
