Faulty Chiller & Replacement options

[EricTrotter]

I have a 6 ft tank with 3 metal halide lights which used to be filled with corals and fish until around 6 months ago when I had a bad electrical fault and the whole tank died. I have been cycling the tank for several months now to start again.

However I turned on my chiller a few days ago (Resun CL 650) and it doesn't work. It was second hand when I bought it at the beginning of the year but was only running a few months before the tank died. so I cant understand what could be wrong with it. the water is being pumped through and the LED display is working but the temperature isn't dropping.

The fish shop said it would cost $40 for the company to come and look at it, it may costs a few hundred dollars to repair and recommended I buy a new one (same type $750 with 6 months guarentee). I think its a scam just to get me to buy a new chiller. Also at the moment I really dont want to pay that much (my last chiller Artica only lasted 2 years and cost me almost $2K) as I need the money to restock my whole tank anyway

any advice on what I can do with the chiller. is it worth trying to get it fixed, is it worth trying to buy another second hand one (where can I buy these), if I need to get a new one, is the price quoted reasonable for this type of chiller

thanks

First and foremost, do you hear the compressor running? If you never hear the compressor running or kicking in, then most likely the compressor is defective and it's going to be very expensive to replace it.

u can contact Derrick 97979910 to help... (thats if i got the number correct!)

$750 for a new resun 650 is way too ex. Can go Chilldown website to check their repair services. If compressor spoil think replace only $200+.

Or maybe only change compressor motor. Maybe can get parts from sim lim tower

I dun think it is advisable to use CL650 for a 6ft tank moreover you are running MH. You need at least a 1/2 hp to support your tank. If your Arctica is still around, why not send it for servicing? I understand this is a very good brand.

[jackywongto]

your CL650 cannot be used on a 6ft with 3 MH.

it is 1/4 HP, max for 650L tank. Brand new at $498

go get a higher rating chiller.

go look at pasar malam for 2nd hand chiller deals.

good luck!

thank you all for your fast and sensible responses. I will follow them all up.

just want to add on...

i'm using the CL650 for my 4ft tank...

i takes about 5hrs to chill from 30deg to 27deg...

i feel that it should not take so long...

anyway, flowrate is about 1000L/hr...

If your flowrate is 1000L/hr, it is far too low already. You need a much higher flow rate and if you are using a pump/powerhead rated at 1,000L/hr, when you take into consideration the head loss, you are going to get a flow rate far less than 1000L/hr.

i'm using a 1300L/hr pump.. so estimate about 1000L/hr...

so do u know wat's the recommended flow rate?

and usually it takes how long to cool the tank?

How high is your tank from your pump? If it is around 1.5m, the flowrate will only be around 60% of the rated flowrate. If you are using an Atman pump e.g. AT-104 where the max head is only 2.0m, then the drop in flow rate will be even larger.

If you are using a Resun Chiller, then you should be aiming for a flowrate of at least 2,000-3,000L/hr which means you will have to use a pump rated at 3,000-4,500L/hr flowrate and has a max head of at least 3.0m.

If your temp setting is 27 degC, it shouldn't take more than 2 hr to cool down from 30 to 27degC. Subsequently from 28 to 27degC, the time taken should only be around 30-45 mins or so at the max.

i'm pumping the water back to my sump...

anyway... i try another pump then...
