chiller pump

[tansh]

Hi,after giving up reefing few years back and i plan to hv a smaller reef tank.

I plan to hv a sump tank with 3 compartment.Arrangment would be skimmer to refug to reture.

Now i hv a question where shd i place the chiller pump for most effective?shd i place the chiller pump at the reture to chiller than back to maintank?

Hi,

If your return is strong enough, your can T-joint it to the chiller.

Intend to use 3000 pump for my tank size 2x1.5x2.May i know how am i going to t-joint the main pump to chiller also

will this affected chiller like take longer time to cool the maintank?

Below is the flow chart for Aquabee3000(blue line).

At about 1.5m which is about typical height from base of sump to top of the display tank, you'd be losing about half(i.e. 1,500l/hr) of its flow. Probably even more if you factor in the piping elbows for your return. With display tank volume at about 154liters, you'd be getting about 9.7x circulation per hour.

Chiller for your tank size would probably require a flow rate of about 1000l/hr. If you redirect that portion from your Aquabee3000 to the chiller, you'd be left with about 500l/hr to your display tank (i.e. about 3.2x circulation per hour), which IMHO is quite low for a reef setup. You may want to reconsider for a stronger pump, or get a seperate pump for the chiller. If you choose to stay with one pump, below is a method where you can control the flow from your return pump.

The T-joint splits your return water, left & right, each controlled by a ball valve(blue pieces). Right leads to your display tank. Left leads to your chiller. By reducing the flow to your chiller, you direct the rest to the main display tank. You'll find the optimum setting by observing the interval of your chiller's thermostat kicking on & off.

Thks for the reply.Think i will hv a standalone EM 1000 L pump to chiller.

Btw shd i place the chiller pump at reture to chiller than from chiller output to maintank?

[Solo77]

Think at chiller output to main tank. . Minimize lost

You've 2 options:

(1) EM1000 in return pump sump compartment --> chiller --> Back to return pump sump compartment.

Pro: Simple. You're getting approx. flow rate of EM1000 thru' chiller.

Con: Extra power to chill the return sump compartment. However, this is quite negligible.

(2) For "chiller pump at reture to chiller than from chiller output to maintank", you'll need a stronger pump than EM1000 for head loss.

If we based on earlier chart with 1.5M head loss, Aquabee2000/1(pink line) would meet your 1000l/hr flow rate requirement thru' the chiller.

Pro: Chilled water goes direct into display tank. Contributing additional 1000l/hr to your tank circulation.

Can do away with Aquabee3000 & use an Aquabee2000/1 instead for return saving on pump cost as well as running cost.

Con: Need extra plumbing into display tank.

Im using Hailea HC150A chiller.Refer to chiller spec i shd use 250-1200L\H flowrate pump.I think 1000l\h shd be enough.

Im getting a 2nd hand aquabee 3000 because of very gd price Anyway i think i would stick to option 2.

Get your chiller modified to use an external temperature sensor. With this modification, you are not limited by the pump flow rate. Place the external temperature at the 1st compartment where the water enter the sump.

Thinking to mod with external temperature probe cos heard that HC150A original temp probe not accurate at all.

Can advice how much and where to mod?

[Solo77]

u may want to contact derrick to check the mod. There are 2 options to mod, one is the external thermostat connected to a socket for the chiller whereas the other is more complex where the external thermostat is integrated to your chiller. The new hailea can calibrate the temperature reading to adjust its accuracy. The worry is the internal thermostat fails you. Hence that explains why ppl go for external.

Hi guys,i hv another question for chiller connection.Currently i hv a aquabee 3000 for return pump.Can i connect from return pump to chiller than back to main tank?

thats what i have going on for my tank except i split it to the following

return > chiller > main

return > fr > sump > (back to return)

You hv 2 reture pump in ur sump?

May i know what pump u use on return > chiller > main?

no no just one ab3000 like yourself. i'm saying its possible to pump straight into the chiller then to the main

Thks.Im using Hailea HC150A chiller rated pump to use 250-1200L\H flowrate .Do u think too strong using aquabee 3000 to chiller than to main tank?

[Solo77]

Depends on the headless and maybe t-off to use one pump for all. Con is one failed, all down .

Hey bro,

Sounds like you've pretty much set your mind on how you'd like to hook up your chiller. Just go ahead without making your piping connection permanent yet. Make adjustment as you go along to get the optimum setting you want. Take you time.

[iskay]

Another advantage of using a tee with valve is that you can unplug the chiller for servicing without affecting your return.
