So what can i use?
Stainless flex hose.
and for oil with r402 any of the standard oils are fine.
Heyyy chilly welcome to my growing thread lol.Quote:

I think no one use something for keeping wool in place. Just fill oil separator from bottom to top with wools
Nice flame :)
EDIT :
I didn't notice new post, this topic is really fast in growing
Stainless flexible hose - it's a hose made by stainless steel and it's corrugated (and thanks to that it's elastical)
There are photos

Go to a hydrolic equipment store, or look in net.Quote:

they are quite cheap and fine. You can cut and braze to copper easily.

Well when you next go th the hardware store look for the stainless steel gas flex line. about 10.00 at homedepot they are a little large but will work.Quote:

Does it matter where i put the separator weather its before or after the condensor just as long its before the cap tube?
I also found some copper wool in the kitchen last night so thats what i used i hope noone comes looking for it :p:
Since theres no place around here to get a block of copper or a place to machine it into an evap i had to take a different route one im not sure will work or not. Its built but im not ready to post the evap on here just yet.
Better before condenser, otherwise oil will lay on condenser's pipes and make worse heat transfering between air and gas
Dangit i already brazed up the condensor o well i suppose i could rip it apart again :( It was gonna go compressor-desuperheater-condensor-oil separator-cap tube.Quote:

What are separator's dimensions?
BTW, what you call a condenser in second stage, it's really a desuperheater
The desuperheater is the small loop of tubing behind the fan when i say condensor im talking about the HX.Quote:

Ah, then ok :)Quote:

ID length is fine, it should work. But fill it fully with wools.. :) PC_ICE had make a lot of oil separators
like as your (but with caps on ends), you may ask him what he thinks about it
It's already filled with copper wool. Now that i know its ok im gonna braze it to the system. BBL with pics.Quote:

Notice the green color, This is a idication the copper tube is up to brazing temperature. learn to read your torchs color pattern and this will tell you when jouint is ready to braze.
Look for dull red copper tube & green secondary flame
ps :nice photo!!!
edit,why didn't the photo didn,t move with the quote look at post 200 in this thread
I don't understand what you mean. :confused:Quote:

UPDATE!!
I installed the oil separator this evening found a nice little spot for it right in front. I flared 2 peices of 3/8 tubing for the oil separator valve and braze a cap tube on to one of the 3/8 peices than ran the cap tube along the bottom under the second stage compressor and up the other side. I brazed the other end of the cap tube to a peice of 1/2 tubing that i had already brazed a shraider valve onto for servicing the system at an earlier date i just need to braze this 1/2 peice onto the suction line on the compressor.
I also bought some switches and wired up both compressors and the condensor fan with the dimmer switch. The condensor fan will come one when first stage is switched on.
Would 90 inches of cap tube be too long for the second stage?
Systems is looking nice good place for the oil seperator, I would of thought that 90” of capillary line would be too short for the metering device for the secondstage (low stage), what ID would you be using ??
or do you mean 90” of capillary line for the oil return from the oil sperator?? Oil separator line can be as long / or as short as you want, any ID would be fine.
It is for the second stage and not the oil separator. How do u measure the ID of a cap tube anyway??? its just so dang small :confused: :confused:Quote:

but as long as it doesnt flood too much should be ok.
i always start long and cut short, co2 is cheap. some time will be suprised what a longer lenght of capillary can do :stick:
Good grief, what are all the valves for? That's ghetto to the max!
You measure the id of a captube with a little tool that has rods the same diameter as the outside of the captubes, and you hold it against it and check.
There are a few of capillary tubes which go to high stage evaporator ;) They have different lengths, those valves
are supposed for experiments (?), you open first valve (other are closed), temperatures are no good, then you
close first valve and open second valve. And you repeat it until you will know which capillary tube will provide
the best evaporating temperature.
What he said.Quote:

Well heres my evap (its all i could think of to use) my problem is i don't know what can i do to make a wavy path inside this unless you guys can think of another way to make an evap. :stick:
check out lardarse's end cap evaps. their very simplr to make and cheap too
