Where to buy phase change stuff?

[3lite]

I want to make a phase change system simmilar to a prometia, but myself (and cheaper:D ). This will be my first system. I cannot find any online retaillers for compressers and stuff, can anyone pls give me some links to shops?

Oh yes Im in switzerland btw.

oh yes and what sort of gear should I get for a single stage R404a system that can deal with ~250W? This will later become the high stage of a 2 stage cascade. Or not.

So, pls list EVERYTHING, cos I don't have any tools at all.

I was thinking:

- MAPP Gas
- Bazing sticks
- Compressor or condensing unit (which one ?!?!?!?)
- Copper tubing (which diameter, what lenght?!?!?!)
- Cap tube (length, width?!?!?!??!)
- A refrigeration valve (what is its proper name?)
- Tube bending kit
- A good digital thermometer
- Oh and R404a of course ;)

I will not have an evap on the low side of this system, as I inted to have an IHS simmilar to berkut's, in his cascade. Is that form of IHS efficent (it doesen't look efficent AT ALL [to me ^^]).

Thank you!

LOL, I had R410a before, it was a typo. It is meant to be R404a!!!!

a lot of people in here track their stuff down on eB@y as you can often find it very very cheap.
search the HVAC section for compressors -- they have some excellent deals in there...you can find new, high quality compressors for as little as $25 + $25 shipping (they are a little heavy)

copper tubing can be gotten from lowes or home depot

cap tubing - check your local phone book for HVAC stores -- the ones around here stock most sizes of cap tube and they are reasonably priced.

if there are no local shops, you can get condensors, cap tube, fittings, etc. here:
