    Hi guys,

    managed to find this Smirnoff bar fridge and was thinking of converting it into a chiller for my future setup.

    Has anyone attempt something of this nature?

    It might work if you drill a hole through both sides taking care not to damage internal pipes etc. Take flexable hose and coil it on the inside of the fridge as much as you can. Obviously the one hole is for the "inlet" and the other for the "outlet" of the hose.
    This hose/pipe will be used for your main return line into the tank.
    One disadvantage though, a chiller will switch off when the desired temp is reached and your fridge will not. ;)

    thanks tobes but do you really think that this small fridge will be able to lower the temp of the tank to a substantial degree?

    Cool fridge ;)

    A couple of people have tried DIY chillers in the past. It's never extremely successful and even though chillers cost quite a bit they end up still being worth it in the end. Rather keep it as a cool looking fridge and get a chiller.

    it would be interesting to convert the fridge into a chiller.might have to install a few heaters in the tank to keep the temperature stable.
    or if you could get some kind of a controller with a probe suck in the tank to switch the fridge on and off would be good

    The people that tried it did not try hard enough. I build a chiller fro m a samsung 18000BTU split unit aircon and it works like a bomBBBBBBBB!!

    Next to the unit is the heat exchanger whith titanium coil(hard to find) and the water sirculate threw it back to the tank. I've got a dixel temp controller to switch the unit on or off keeping the water at 26 degr C

    Using the fridge as is, is a waste of time. Yes if you know what you are doing it can work. The fridge just takes to long to get cold. You will need to change the heat exchanger, and you may end up just using the compressor, at the end of the day if you have to pay for controller and other things, and you don't have the knowledge, just get a chiller. Remember you will get a warrantee with a new chiller.

    I baught it down in cape town,but look on the internet dixell xr10c.
    The titanium coil lies inside the heat exchanger and this is connected to the 2 copper valves outside the unit. When the condensor switch on it basically freezes the coil in the heat exchanger and cools down the water as it passes through the exchanger. Your temp controller the obviously sense the temp of the water to switch the unit on or off.

    You can convert any old split unit to a chiller,but first find yourself the coil as 316 stainless do not last in seawater and remember each size of condenser 12000,18000,24000 needs different lenghts of coil to make it work properly.

    Hey Bernic. When I said they haven't been very succesful I was actually referring to the "fridge" chillers. I'm sure yours works very well with 18000btu! (over 5HP)
