Any reason for doing that?
Some of the members do connect two filters inline with one chiller.
as above just wanna check anybody try using a big chiller connect to 2 external filter and tank? hope some one will give a reply as saving some cost to try out.

i was thinking doing 2 tank for crs and just connect 1 chiller and 2 external filter. .don't know its work anot. .so trying ask any member have try before. 2 inline with chiller but in 1 tank?
Err, so is two filter filtering one tank or 1filter doing 1tank each? Sorry, abit blur here.
1filter doing 1tank each. .but will be in different size of tank and 2 different kind of ehiem filter.
Actually you can do that. That is normally how a chiller is used in the industry.Originally Posted by jiahe88
chiller==>reservoir==>external filter 1==> tank 1
==>external filter 2==> tank 2
The only thing is the reservoir has to an insulated container. I think those cooler will do...
If you don't understand you can call me 9027 5964. I will just charge you my normal consultant fee. 2 cup of kopi O with little sugar...
The consultation fee is non negotiable..
i will call you but not today. .Question 1 : in 2 different size of tank is okie? Question 2 : will the flow rate slow down also? Question 3 : 2 different size of tank and different kind of ehiem filter will cause any over flow the water ? cheers
Q1: This system is independent of the tank size. The only thing is the size of the reservoir container.
Q2: The flow rate I think should be better.
Q3: The answer is the same as Q1.
But there are some drawback in doing this.
1. The 2 tank water will be mixed.
2. The temperature will be a bit hard to control (if the connection is simple) and you need 2 extra external filter the same size as the first 2.
3. And if you want the temperature to be able to control within 0.5 all the time is going to be costly and some automation stuff have to be installed.

I think you have missed 2 pumps to pump water from tanks back to reservior.
Note: The pump and filter flowrate must equivalent or else overflow will occur on either tank or reservior.
In long run, it not economical as need to stronger chiller + 2 extra pumps = higher electrical bill. Moreover, extra space needed for reservior + hard to maintain the temperature constant if reservior small.
Just my 2c opinion.

It better to work with a centralize reservior.
Chiller -> Reservior -> Filter1 -> Tank1 -> Pump1 -> (cycle water back to reservior)
Likewise for tank2.
Water change and adding any solution could be done on the reservior. On the other hand, more water used and more solution needed.

nys,
yeah, I know. I amended it but don't know why it is did not corrected.
I suggest to use 2 same external filter instead of pump in view of different flow rate.
Actually, this is how it suppose to work.
chiller <==> reservoir ==>inlet of filter 1 ==> outlet filter 1 ==> tank ==> inlet of filter 2 ==>outlet of filter 2 ==> reservoir.
filter 1 and filter 2 same model to ensure same flow rate.
If you want a more complicated one also can..water can maintain within at 0.5 degree.
Er... Your suggestion are to work in serial connection. But still need a pump to draw water back to reservior. Btw, you have missed the 2nd tank.
It should be outlet of filter 2 ==> tank 2 ==> pump ==> reservoir

If your reservoir is at a lower lever than your tank you can use an overflow pipe instead?
chiller <=> reservior => filter => tank1 => overflow pipe => reservior
Same for tank 2. Or if you have a 3 tier system, tank 1 (top tier) overflow to tank 2 (second tier) over flow to reservior, then you only need 1 filter and 1 chiller. Don't know if it's effective or more economical compare to seperate small systems or not but this will remove the need for 2 filters for 1 tank which is a bit more dangerous because it is hard to ensure same flow rate even with same model.
what you all said are very blur to me.
if possible life demo will be good or else do oneself very costly.
new to this stuff
kopi on me
Don't sound workable to me if there is a reservoir. The out flow will be faster than the in flow to the tank (assume the reservoir is lower than the 2 tanks). In not time the reservoir will over flow and each tank will be drained dry. It will only work if use a IOS tank.
Never test before, just my thought. Logical??
Strongly agreed that it quite difficult to ensure a constant flowrate.
Regardless the connection are in serial or pallaral, using pump/filter to draw water back to reservoir or overflow method, there are high possibilities of either water almost draw empty or water overflow when equipment failure or "inbalance" function.
Well, is pretty complicated. We have a PLC to control all this thing at work and we use a motorized valve, solenoid control directional valve to control water flow.
And since jiahe88 has 2 different tank and filter size is going to make matter worse.
What luenny suggested only works if the 2 tank is the same size or else the temperature in the both tanks will be different.
In order to make it work better at least 5 pumps is needed.
After a day work back and see throught what stephen AQmembers reply the threads i have think of reject this project. .really make worse in the end if never do it well. .actually is to cut cost end up make the cost more high. thanks anyway brother for the reply.
Maybe, I'll do 1 for myself...no chiller just filtration...
that good keep it up. .success show some picture out to let us view.
