Comparison of power consumption of different chillers

[Ebi]

Hi Bro and Sis,

Can anyone provide some figures on how much difference is the power consumption between the different makes of chillers.

I am running an artica mini currently and was considering getting a Resun CL-450 for my next 2 x 2ft tanks. Heard from friends that the power consumption might be higher vs a similar artica model. But the artica cost a few times more than a resun

[ranmasatome]

Artica mini operating for a total time of 6hrs everyday = $1.74 (50watts)
Resun 450 operating for a total time of 6hrs everyday = $15.62 (450watts)
Difference = ~$13.50 per month.

Say a chiller last you 5years - that is 60months.
money saved = 13.5 x 60 = $810

Cost of Resun 450 (according to aquamarin website) = $398
Cost of Artica mini chiller (according to aquamarin website) = $888
Difference = $490

Total savings = $810 - $490 = $320

So technically, if you bought an artica mini and used it for 5 years. You save $320.
The longer you use it.. the more you save because cost is fixed but every month you use the artica over the resun, you make ~$13.50.
Moreover, artica will most probably last that long.. don't know about the resun.

The artica mini seems too efficient to be true. Do they both have same chilling power?
I mean comparing a 50W with a 450W model?

only 50W? hard to believe

Searching website and I only find the smallest model is 1/15hp. It does not mention wattage but it mention 2Amps. There is no way it is 50W

If the Artica Mini is only 50W and with the same cooling capacity as CL450. I will buy the Artica without hesitation even it cost few times more. May I know which model is that ?

Hi guys,

Sorry for the confusion
I am not asking for comparison between the Artica mini and the Resun CL450. They are slightly different categories.

I got the Artica mini for my 1.5ft 25-26 litre tank. I have asked around and was told that it is among the most cost efficient to run due to lesser power consumption. However that wasn't the main reason I bought it. I wanted to eliminate the possibility of copper poisoning to my shrimps (hence skip the cheaper models before) as it uses titanium, which paradoxically, isn't as efficient a heat transfer material as copper.
The only thing I can confirm is the extremely silent operation it offers.

I was considering a 2nd chiller for my 2 x 2ft 60-65 litre tanks and I do not think that the artica mini would be able to efficiently handle that capacity although the specs say its good for 40 gallons.
The next level for the Artica is probably the DBA-075 which costs over 2X the price of the mini. I was looking for a cheaper alternative and was recommended the Resun CL450. Have looked around and there are both good and bad reviews on this brand.

Since I don't have a different model to compare, was jus wondering if anyone here uses different models for the same set-up and noticed different running costs. If the costs over time really is significant, then I would just have to dig deeper into my pocket and get the DBA-075.

Anyway thanks for the feedback so far... hope the above clarification will help encourage more feedback...

I have resun CL-280 cooling 3ftx1.5ftx1.5ft tank. Everymonth electricity cost around $8 to $10

Thanks for the info Bro,
Is the CL280 using the thermoelectric method and not the hp compressor?

I thought the thermoelectric method consumes power continously and varies the output (cooling capacity) via the speed of the fans?
It appears your cost is about the same as mine (Artica mini - 1/15hp)

If you are using only the CL280 for your 3ft tank, then I believe the Artica mini should be able to handle my two x 2ft x 1ft x 1ft tanks.
Btw, what temperature are you maintaining in your 3ft tank? Mine's at 25C.

[Shadow]

is compressor, 1/10 hp. Temp set at 25

Thanks for the info Shadow-san

a 2 feet tank is 15 gallons.
2 of them will make 30 gallons.
That is still lower than 40.
Still having said that, i am "kiasee" (scared of dying) so i also got a DBA-075 for my tanks.

As for wattage...look up daeil and you'll realise that the models reflect the wattage.. for example..
The DBA-075 model uses 75watts
Its the same for Resun - hence resun280 is 280watts. 450 is 450 watts..etc etc.

So i presumed that the DBA-050 uses 50watts. At least we know the DBA-075 uses 75watts. and even comparing that..it would win hands down. Its one of the reason i went ahead and got arctica/daeil. So believe it.
Arctica is the same thing as Daeil.. just OEM.

Thank you for the info Ranmasatome-san,
I have managed to get more info on the Daeil chillers. You are correct about the 50W for the mini, i.e. DBA-050.
I have tried to attach the specs of their range here but failed as the file size exceeds 200kb. Sorry.

[Shadow]

can send the link? based on the current requirement writen on the web there is no way it is 50W.

same goes for DBA-075, I would guess that the web site is wrong but can be so sure until someone really measure it

[Ebi]

Ooops, how come I did not think of it?
Here's the link: http://www.daeilcooler.com/en/pdf/Aq...%20Chiller.pdf

Here's the company's website: http://www.daeilcooler.com/en/goods/aquaruium.asp

[ranmasatome]

So hard to believe meh? how come no way it can be 50watts?
come to the dark side la...lol..

By the way, most chillers name their chillers this way.. resun 280.. hailea 500..etc etc.

[Shadow]

it is hard to believe because the math does not add up

For example the web site below
http://www.quickpets.com/index.asp?P...ROD&ProdID=851

mention that for DBA-075
Horsepower: 1/10hp
Capacity: 1270 BTU/hr
Voltage: 115V
Amps: 2.63A
Flow Rate (min/max): 4/16 gpm
Dimensions: 16.5" x 9.8" x 18.5"

Thus power would be 115V x 2.63A x power factor. That would be ~300W

On the other hand the Daeil web site said "capacity of compressor = 75W"
Question is does the capacity of compressor = power consumption? ot it is just most website put the wrong data.

[williamng]

75W for a chiller is pretty remarkable.

I think the capacity of compressor and power consumption is different. One might refer to the capability of the compressor whereas the other might be how much power the chiller consume..I maybe wrong..

[Goondoo]

The only true way of measuring the power consumption is through the current. There are some 3 pins digital meters these days that do that.

That was my guess

Just went to NA and saw the Artica chiller. Take a snap on the spec written on the artica box. As you can see from the box the supply is 115V and current 2A

[IMG]here the spec at artica box. As you can see from the box, for DBI-050, the supply is 115V and current 2A[/IMG]
