Resun CL450 or CL650

[Rocks]

Hi everyone...

am going to buy a Resun chiller... either a CL450 or a CL650

I am having a total 420liter setup (tank+sump) and running T5 4x39watts lighting.

Will a CL450 handle my need or i need to get a CL650?

I gathered

CL450 = 450watts / 450 liters tank (S$450)

CL650 = 650watts / 650 liters tank (S$550)

any advise please...

For that tank size, maybe better to go for CL650. CL450 good for 3ft and below, some will use it even for 4footers. But for your tank size, better to opt for 650. Using a 450 for my 2 ft.

I thought CL650 is 1/4hp??

how come it used 650watts n is good for 650L..??

where u get such information?

Strongly recommend CL650. These Resun chillers are cheaper and of lesser. Oversizing them will certainly not hurt, it will just reduce their working time and extend their lives.

I got a 4x1.5x1.5 tank + 2x1x1 sump. It chills it by one deg in less than 10 min (no MH yet)

can tell me the hp of CL450?

[Nautical]

i am using CL450 for my 3 feet tank.

the CL450 is 1/6th hp.

oh

I'm thinking of getting a chiller.. thinking resun 450?? is it quiet??

How much is one set? where would I be able to get a set?

[Rocks]

Resun information got from the Resun website (Resun Chiller)

My is a 36"x24"x24"(Tank) and 30"x18"x16"(Sump) ... total litres after minus liverock, sand ... should be around 400litres of saltwater.

Looking at the website's information... Resun CL450 can cool a <450litre tank setting for 22DegC or <700litre tank setting for 25DegC

Maybe a CL450 is enough ... but then a CL650 (capable for <1000litres for 25DegC) can cut down the On/Off frequency and also requires lesser time to cool the tank... Hmmmm .... ... which to choice?

how about noisy level ? any one has any idea ?

your CL650 .. how often it turn on/off ? (example: 3 times in an hour)

and what is the duration each time it is turn on? (example: 10mins)

Hi,

I hav a Resun cl-650 to let go at S$350.00. Used only for 5-6mths. In good working condition. Hav manual. Self-collection at BP (Bedok Nth).

For your consideration. Thx.

I have a 100 gal tank (quite similar size with yours) and I'm using Resun CL-450 chiller. I set it to stabilize the temperature around 26 C. It's been doing the job quite well. I tried to lower the target to 24/25 C, but I notice it's working much harder and longer than usual, so I decided not to try it anymore.

If you're targetting 26/27 C for your tank, I guess CL-450 is more suitable and you can save the extra money for other stuffs. Otherwise, CL-650 should do the job better. Hope this helps. Cheers!

twrs, yes your feedback helped...

By the way, your CL-450 at 26degC is doing the job quite well...

Can you give a bit more details..

How often is the chiller turning on/off (example: in every 15mins ?? and each time when it is turned on, it run for how long (example: 10mins?) ...

This info pretty much help me to decide whether CL450 or CL650 model..

Hi Ivan,

any reason why you are giving up this chiller? 6 months of age is the older batch of CL-650?

CHEERS !!

bwilly,

yes i too find it strange... CL650 is a 1/4HP and the spec should then be 250watts rather than 650w specified in their website... hmmm ....

maybe i should feedback to Resun (i am exchanging email with Resun China's representative).

LiveRock

[Rocks]

generally 1HP = 746watts (some website information says 1HP=1000watts)

as such for a CL650 - 1/4HP chiller... should be 186.5watts ??

Am i right ??..

Wa.. make a lot different to my electricity charges ley ...

[bwilly]

the specs does seem wrong..

looking at my hailea manual, 1/4hp can only cool up to 260L tank..

1/2hp is up to 380L. (rated up to 16c - 380L tank)

From the performance curve, my 1/2hp can go to maximum of 16c of a 380L tank. It can cool 28c up to a 700L+ tank.

I wonder how a 1/4hp (CL650) can cool a 4ft tank which is abt 120gallon or 450L? And the wattage and 1/4hp does not seem to match.

At the price of $500+ for a 1/4hp - cheap, can cool 4-5ft tank??

How come nobody go n buy??

Maybe new technology n improvement?

agreed..

wonder who is using Resun CL-650 (new batch) to clear our doubts...

hmm ... seems like Resun's website over boost their chiller performance.

[bwilly]

Most 1/2hp can barely chill their 4ft with MH blasting..

this new batch of 1/4hp seem to be able to do better..

Most 1/2hp better chiller start from near $1k onwards.

Resun 1/4hp if can perform better and at almost 50% cheaper than is veri good seow..

[Rocks]

do you think the new batch of Resun Chiller CL650 so solid? with just 1/4HP at 50% cheaper and can do the job of a 1/2HP unit?....

I think i share the same sentiment as you....

sigh... started off this topic so that i can decide which chiller to chill my 400liter tank+sump .. now end up back to square one..

[lightningstrike]

why not consider long term..... once and for all go for Daeil?

[Rocks]

why not consider long term..... once and for all go for Daeil?

have you used one before? which model and how's the performance?

[lightningstrike]

i hv not used it..... but looks good to me...... hv many reefer frenz using it...... try starting a new thread and ask abt this.

[ZeRoC00l]

I'm using a CL 650 for my 250L tank.

Working ok till lately... Turns on very often now.... switches on/off 2-3 X/hr

it has no prob for chilling my tank down to 23 (tried once to test the efficency), my chiller placed outside my house with good ventilation.

Tank w all equip running: 33 degrees

but after chiller: 25-26

Gota check my bill this coming mth, and see if i shoud get a ext. temp prob.

*** think the temp prob not very good

1/2hp is up to 380L. (rated up to 16c - 380L tank)

Did you see how the rate the chiller?

They actually run the chiller w/o any heat load with that certain amount of water then wait for 16 hrs for it to drop to that particular temp. Then you have your rating there already

With the heat load in our tank, I think the chiller cannot deliver

Hi,

I have a CL-450 only 3 months old, selling at $390.

It is from the new batch, black in colour. The new batch is heard to be better, but i know quieter for sure.

Running on a 100 Gallon tank with halides. It is quiet and in good condition. The noise only from fan. Should be no problem for your tank, if your on a budget why not give it a try. I am selling to upgrade to maybe Artica(More stable temp). PM me if interested.
