I stumbled upon something new and interesting in the new CORAL magazine (March/April). To cool a 2000L system, you only use 88W - AWESOME :thumbup:

inlet / outlet
Ø 40mm / Ø 40mm

technical data dimensions (l/w/h) app. for aquaria up to power consumption
Eco-Cooler 320/2 (S) 390x370x360mm 2 fans 600 ltr. 44 Watt
Eco-Cooler 420/2 (M) 490x490x360mm 2 fans 1000 ltr. 44 Watt
Eco-Cooler 420/4 (L) 770x490x470mm 4 fans 2000 ltr. 88 Watt

Whoa, are these available here??
 
Its an evaporator, like the cooling towers of a coal powered station, generally work well, but increases the water loss big time.

Looks like it could be made of metal, this could be a problem.
 
Yes, like a cooling tower. Uses a big coarse sponge to distribute water, then blow air over it. Resulting in evaporation. Not sure if very humid areas like Durban if it will be as effective as Pretoria. Must have an auto top up with big enough storage holder. Also needs to clean the sponge frequently to prevent it to become biological. I doubt if Deltec will use steel, it looks like acrylic. But only 88W, now that is something.

Also do not know if the fans will last more than a year in such a humid setup. But electricity saved is mush more than computer fans costs
 
are there any cooling systems that run water through thin piping and then cooled by fans. Evaporative seems like a very wasteful way to go about it. I'm sure the elaborate CPU cooling fans and water tower designs would be effective... Would just have to be on a considerably larger scale...

like adding some fans to this...

Or combining a Scrubber into the cooling tower. Doing two things with same effort.

Now there is an idea worth thinking about.

These are on the deltec site. [URL="http://www.theaquariumsolution.com/products-type/coolers"][url]http://www.theaquariumsolution.com/products-type/coolers[/URL][/URL] using their idea i just put 2 pc fans over my scrubber. temp is stable now but evaporation has doubled. so it has ups and downs
 
I wonder how long the fans last?

I would have to disagree, Evaporators are very effective in cooling. A cooling system where the water just runs though a thin pipes (like above) wouldn't work, its designed to cool something much hotter than ambient temp down to ambient temp, where a evaporator can cool way below the ambient temp, it uses the evaporation process to cool the water, like sweat does to a human.

i agree this kind of cooling is desigened to keep a cpu at about 50 degrees i dont think it would make any diffrence trying to make water drop a degree at low tempretures.
 
Evaporation rate be inversely proportional to the rise in humidity. meaning for there to be no evaporation there would have to be 100% humidity. So even at 99% humidity there still evaporation just alot less that 0% here is a link that explains.

There is no real cheap way to keep things cool, an aircon or fridge is one of the most efficient users of electricity.

water evaporation is natures way to keep things cool. a radiator would work but we can't use metal so it's of no real use!

one needs to decide how best to keep their system cool.

I am thinking or using a fridge to do the job - the idea would be to have some metal pipes as a radiator in the fridge connected to some silicon rubber piping in the sump with a pump to circulate the water.

You might aswell go for a chiller Vatso - We have had a thread on this issue before. A fridge is not designed to constantly cool and the compressor will pack up quickly. You will also have a problem with the thermostat and keeping the temp constant. Look around for a good secondhand chiller - I think sims has one.
 
A fridge currently does keep goods at a "constant Temp" the idea is to have some metal piping with water inside the fridge keeping that water at a constant temp & when needed the pump circulates the water through the fridge into the sump water.

The best way to do this would be have a small radiator in the fridge with water & a small radiator in the sump connected with a pump & some piping. the radiator could be ally in the fridge & plastic in the sump

well at 44W to cool a 1000L, that is cheap.
