Plate HX are the best for such cascades. They are a little bit more expensive, but its worth the money. When you buy a plate HX from ebay, check that they are rated to a minimum of 20bar!

has the oil sep got a automatic valve that returns the oil when needed ?

thanks baz

commercial seperators have a float inside that opens and return oil as needed.

This cascade costs about 1400€.
The oil separator is very expensive, but its one of the best.

i would agree, those plate hx and oilsep are expensive, and offcourse those 21CLX'es are not the cheapest compressors around :D

Wanted top finish the unit today, but had not enough time for the cascade. But I only have to do some brazing joints tomorrow. Can't wait to turn on this baby :D

It looks awesome man, great job !

clean job as ussual :toast:

hows that oil sep working?

tested the henry s5181 and it still let some oil go...

I didn't test the unit yet. Maybe today or tomorrow.
I think esdee said that the OUB1 didn't let any oil go...
Maybe I should put a sighglass after the oil separator :D

sightglasses are cool ! :p:

hehehehe

Very nice! Can't wait to see it running :clap:

Second stage complete. Hope I can charge tomorrow.

Any update ?

I had a small leak at the relief valve. Took some time until I found it. I'm waiting until tomorrow, I hope there is no leak this time. Cant wait to fire her up.

ok Good luck :D

Today there was no more leak, so I vacuumed and charged her. Filled it with 10bar ethylene. Load testing will follow tomorrow.

I love such pictures :D

I think the probe of the thermostat is faulty, my temp meter reads -44° one the same spot.

very nice work

:eleph:

amazing!!!!!!

wont you get better temps if ur 1st stage was a little bit colder,??
colder hx= lower high stage pressure= lower high stage suction pressure= colder temps

(i am a cascade noob)

A nice unit again cold ice! realy like the way you built. It's very clean.
What's the status of your monster on the background?
I cant wait to see that baby fired up.

congrats on this one :toast:

1st stage is about -45°, so that seems quite good to me. Condensing pressure in second stage is ~11bar so that is -46°C condensing temp.

4 stage cascade is still not ready because I'm waiting for either a TEV or a CPEV for the third stage.

how come ur thermometer shows 29C

I wrote something about the thermostat and the high temperature above... My temp meter reads -44° at the same spot where the probe of the thermostat is located. Maybe a broken probe or bad contact.

ohh.
any ways
amazing work!!!!!!!!

:clap:

i hope to be able to build something that clean some day!
