Cosmo chiller

Hi

I want to show You my last chiller project - it's chiller to cool CCD camera in home astronomical observatory :D .

Specs :
compressor: Aspera NE2134GK
heat exchanger: plate HX 12 plates
XV: captube 0.8 mm, around 190 cm
condensor: 1.9kW cooled by orginal 230V fan
refrigerant : R507
case: metal case 55 x 50 x 43 cm, black powder coating
others: electronic controller Everycontrol (from -40*C to +99*C), two 230V fans 120/38mm on the back of case .

Chiller takes around 350-400W :) .

With some insulation stuff .... :yepp:

very very nice.. :) I'm planing to build a chiller my self.. :)

hey what pump do you use??


your casing is looking good.. :woot: I hope to see it in action.. :)

Very Nice Peter :up:

case is fairly large for a basic chiller, but looks good nonetheless

Case is so wrong, just look like you have taken a Cascade case and modded and it then sprayed it up.

Well in fact you have!

Meh still not bad at all -31c water!

what hoses are you using there?

Customer use quite crap 400l/h pump from Tt Big Water kit :ROTF: :shakes: . But I think I'll be replaced soon.

Hoses are ordinary, cheap 12/10 mm hoses from local shop . :)

Yep first that had been planed to be cascade case ...:D but not sprayed, that powder coat :D :D .

Pics in action soon.

Peter

I want it.

Two pics from customer, instalation of chiller is for me bit messy but that's not mine problem I think :p: .

@2long4u : I want sth like BMW M3 or Lancer Evo ...and cash for gasoline :D .

How about a 77 chevy with 4"lift kit and 35x12.5 BFG Mud terrain tires. You could run over both thoes cars. It is soon to have a new engine built by yours truly.

Now he's a hard core astronomer! Reflective telescope, they be the best!

Hey want to know where to get the perfect load tester for chillers? Thoughs cheap water cooler/heaters! I just got a 490W heater out of one in a ready made shell! Look into it mate!

That's a nice CCD cooler. Must get very little noise. But I gotta wonder where the user could set the telescope up where he could both: use the chiller and: be in an area where you wouldn't get light interference. That thing would suck up batteries rather fast but I guess you could use a generator.

For a CCD thats not much of a heat load, it would be easy to make a low temp chiller that only used up 2Amps.

quick question, using a larger plate hx cause any probs?

No not really in a system that small, just wasted material that could have been saved. a simple home made Hx, and a 300W Compressor would have been more then enough for that system.

good to know, got my eye on a 30 plate on ebay for cheap

well, 30 would be too big, as you do have to maintain a certain internal volocity, I'd say 16 is pretty big for such a system, but not horroridly over sized.

I'd go to rons shop and get the 6,000 BTU Coaxial condencer, they're cheap and will work well. That way gravity will be more then enough to ensure oil return.

how much does it cost to get a chiller made ?
i would like to cool my gpu and ram

Depends on how fancy you want it, and if you want all new parts.

:eek:

Awesome work

I'de love to build something like this.

How much for all new parts? roughly that is :)

I think it's mean last built chiller, not his last chiller overall ;)

Maybe ;)

Sure ...it's mine latest build :D .
