Is it okay to use a Delux condenser from Cold Ice (Pat) that are rated for 500W with a 12,000 BTU rotary?
I will have a DSHC between the compressor and condenser.
Fans are 240v but i might change to some HIGH CFM Deltas as the case is PC case.

In my opinion it's far to small. This rotary probably has 1HP, so that's 750W + 250W heatload + some reserve (200-300W) = I would go for 1,5kw condenser.
Really don't have much space, 7.75'' wide 18.25'' length 17.25'' height. I can just fit the 2 12,000 BTU's in there. I can't make the case any bigger
Compressor is a - Toshiba PG180X1T-4CZ (out of a 12000 BTU AC unit from Homebase currently gased with R407c). Im trying to find more specs but not having much luck

Little off topic sorry, but I have four condensers, however they are from AC unit so I don't know what they are rated as (in kw). Is there a way I could calculate their kw rating?
If you are trying to stuff a single-stage into that small of a box you are best getting a smaller compressor.

Thank you
Find the BTU rating on the original AC unit, that'll tell you how much heat the condenser was rejecting after adding in a little to compensate for heat of compression.

Its a 12,000BTU unit/3.5kw unit? So the condenser is around 4kw?

2 12k BTU single stages in that small box. The small box is a tipical american mishap of pure sex though!
What if i used some of them super duper Delta 220CFM fans, 4 of them. 2 intake and 2 exhuast?
880 CFM

Random idea as i've just finished playing a little with it all. Water cooling in place of the air cooled condensr. I could mount rads 120.3 i think (just need to dig one out to check) and have some high CFM still so compressors are kept cool as well and have pipe in a pipe HX's that are the length of a 120.3 rad and fairly thick in terms of the length of copper pipe used. I have room above the compressors as well but i would have issue would i not with the refrigerant pumping around?

Showing the lack in my paint skills here is a rough idea of how i could WC this beast with the one compressor. This would be in reverse for both sides and both units within the same case. Idea is to have the HX the full length of the compressor, thus should allow enough cooling to the system!

Just had a complet brainwave on how i can maximise the cooling in the pipe in a pipe HX. It come about as i was thinking of the rows and drops that are in a condesner. Thats whats i need to obtain here really. Sod doing a round coil of thing. Do a box/block wrap around.
Thus i can use the full 7.75'' width i have and the 17.25 height. Admitly i need to measure now i have opened the case up some more!
So say i do it at 7'' width and 17'' in height. Thats thus...
7 X 17 = 119 X 2 = 238 (2 width sides)
Then if i do it so the block i wrap around is 2.5'' thick it then...
2.5 X 17 = 42.5 X 2 = 85
238 + 85 = 323 inch = 26.9166667 feet just as the coiled section alone.
There of corse will be a bit of a run off from the stack anyway plus as it bends due to the bend radus. Just glad the copper comes in a 15 meter roll!!
A quick Google on bending tubing seams i incure 4 times the tubes OD in the bend length @ 90*! This way over my head admilty. So being the cleaver sod and clogs i am thats an extra
1/2'' tube OD X 4 = 2'' bend radus
17 X 4 = 68 (4 corners or bends per row, 17 each side)
68 X 2 = 136 (68 corners total @ 2'' radus)
So taking the last number we got for the stack length in tubing and adding the radus from the bends...
323 + 136 = 459'' for the total length on the stack.
Thats still not inc any run off from the stack to the compressor etc.
459 inch = 38.25 feet or 459 inch = 11.6586 metres.
Just as well they do come as 15 meter coils i think!!!
Okay so one this going to be a right PITA to put the 1/4'' into the 1/2''. Gonna need a massive working area. Then the coiling up of it as well is going to be some effort.
Is any of this post making any sense to anyone or have just amazed my self with some random googling and calculator effort that produced numbers that mean nothing too me or anyone!

I've been a fool. I have 17'' in height within the case. Im using 1/2'' OD tubing not 1'' OD like i was for god only know thought i was when working this all out. Well duh.
So rethinking in 1/2'' OD and with the full 17'' i have and now having the 2nd compressor at last (although slightly different sadly but not much).
Red is the copper coil and black just the mold to wrap around. Sadly im over 15m so it'll have to be backed off to say 16 coils around the block.
Here is a photo showing the 2 comps in the case with the possible layout. You can see where i plan for the stack to go.
Im toying with the idea of using 2 240mm rads and having them mounted in the top with the high cfm fans drawing air in from outside and blowing it down over the compressor. Should keep them cool i think. I need to measure this still. Failing that then a 360mm radin same set up. Or 2 360's stacked with 3 38mm deltas puliing air through them.

There isn't any chance you could source some smaller rotary compressors? We have some cheap 1/2hp rotaries here in the US, they would do the trick for you, shame you are on the other side of the globe.
If you are deadset on doing the watercooling thing maybe you should look into some brazed plate heat exchangers to use as your condensers. They are stupidly compact which will give you lots of room to stuff radiators into that chassis in order to dissipate all the heat from compressor. You are going to be rejecting something like 1kW of heat through your radiators, going to need a lot of fins and air Your other option would be to do a remote radiator or water barrel.
Also, if you go this route you'll probably want to look into some high-side pressure cut-outs. Fans typically fail and give you a lot of audible warning but pumps have the tendency to just die. Two 12k BTU compressors pumping heat laden refrigerant through your heat exchangers will quickly hit dangerous pressures without water flowing through the heat exchangers.

Indeed she is an Apple G5 Mac case. Gutted big time which took me about half hour was fun. There put togther really well which is amazing.
Fail safe i have already though of 2 HPCO like Poitres used on his chiller cooled rotary unit. I've WC PC loads and have sadly had the failed fans and pumps so this was my back up on nothing exploding.
If i could get different compressors i really would but i have no idea where. I got these and there new, just i pulled them from two AC units.
I have though of brazed plate HX but though a pipe in a pipe would be better as has more internal space/length.
Fans will be Deltas, 190CFM as thats all i can get hold of sadly.
I might have to ebay the comps to get some funds which would allow me to get hold of some new comps. You got a link for the ones you have states side?

Problem is you guys use single-phase 220vac, correct? There are often some 220vac 1ph compressors available on ebay in the US but they are always gigantic, usually 220vac 1ph is reserved for "large" applications where 110vac 1ph can't safely pull enough current.

Yeah where single phase 230v 50HZ on our mains in homes.

If you were actually pumping 12,000 btu/hr that's a heat output of 3500 watts, not including heat from the compressor motor. I'd say you're way undersized with a 500w condenser and even a huge de-superheat coil.
At even 1/4th capacity of the compressor you're at >800 watts before compressor heat load.

Umm so im kinda screwed ether way then on getting any cooling for the comps and the system heatload

I have not ordered any as idealy i want to use the 2 brand new 12K BTUS i have here as i have no idea what size i would be looking for as a replacement.
It's looking to be a really tight fit for everything going down the WC root.
Pete has 2 1/4 HP rotarys that are horizontal which would fit and probs could be used with a 500w condenser. I guess i could get them off him and use them
1 HP = 745.699872 watts (12000 BTU comp, no heat load added)
1/4 HP = 186.424968 watts (Petes comps again no heat load added)
