Recommended Flow rate for a Teco TW6

[Guinness]

Question as per topic.

Noticed a large jump in electric consumption when i switched to using the Teco together with a Atman 105.

I suspect perhaps the flow rate is too high leading to the chiller having to work for a longer period of time.

There must be quite a number of Teco users out there.... gimme a tip will ya

Cheers

check Teco official website for recommended flow rate

[Guinness]

If I could have found it, I would have gladly done it.....

The teco website i found was all about car and bike wheel and tyre changing equiptment.

.....no car and bike wheel and tyre changing equiptment info here wat

errr....... Thanks Roid,

I think the one i visited was www.teco.it (and no i don't work for them! this is not a plug).

no problem...

the manuals are very detailed in there....pdf format

bro, i hv checked out the teco website, but nothing is said on the rec flowrate. u can contact aquatechnic for the recommended flowrate.

oh yeah...the pdf files in another site....let me see if can find

but somehow i feel the recommended flow should be in gallons instead of l/hr...

400l/hr seems too flow...

400 gallons/hr seems more likely...

I have had a reply from elsewhere..... here is some help for others in my predicament.

Oh MAN!!!! Talk about serious overflow!!!!!!!!!!!!!! Going to head down to my neighbourhood fishie shoppie IMMEDIATELY!

[lightningstrike]

me oso think 400l/hr too slow liaoz.

[Guinness]

400 gallons is hellavalotta water bros....

[lightningstrike]

but 400l/hr really 2 slow liaoz IMHO, think the best is u give aquatechnic a call to verify la......

[yus75]

the slower the flow means the contact time between water n chiller wil be longer

higher flow means shorter contact time

jus n xample here....

if u shower using water heater full open the the tap(higher flow), u get warm water

now half close it(lower flow) u get warmer water

[lightningstrike]

but 2 slow a flowrate oso means ur chiller work longer and harder.......

[yus75]

yes mayb.....anyway how long or short ur chiller werkz all depend on ur overall set up,....

[Guinness]

Chill folks, I'll give them a call tomorrow, and settle this.....

WATCH tHIS SPACE!

[lightningstrike]

cool....cool..... me juz trying to find out more 2 (though i dun own a teco) no hard feeling yah yus75???

[yus75]

hahaha me no hard feelin la.......jus say my opinion only hahahah

Just now checked the teco manual. They have mentioned minimum required flow is 400 lt/h for RA 200, RA 240, RA 680. 1000 lt/hr for RA 2000.

[riot]

The RA680 comes with an internal restrictor, I run an eheim 1260 thru it and the return is very low flow. Also, the internal coils are very short. I suspect they need the slow flow rate to cool down the water effectively due to the shortened coils.

But then again, Im no engineer. My personal observations, just to help Guiness a bit. Hope this helps

Thank you to all those who have contributed their ideas.

Anyway, I have just phoned the agent and managed to speak with lady there (really should have got her name, but i forgot). She was very helpful, getting information on my positioning and setup and giving a recommendation (rather than a "...oh just use a XXXltr / hr pump").

My chiller is beside the sump and intake on the same level, then return direct into main tank. (I really wanted a intake AND return to tank, but the extra piping work involved is substantial. Maybe 1day i shall get round to the mod).

Suggested pump flow rate is 2000ltrs/hr

For those of you intake from tank and back, perhaps a little more.
