DM Cascade. My first Unit...

[Baron_Greenback]

Right guys I thought I'd share this with you as its my first attempt at building anything phase releated.

Im building this with the guidence of a couple of guys from BenchTecUK.

Advice and suggestions always wlecome


Luve 194 Condencer



A few shots of the case im constructing









28cc 1st Stage and 14.6cc 2nd Stage











Lineset and a few other bit and bobs...













I'll update this thread with a bit more detail later in the week as Im waiting on bits to arrive and I gotta finish the case off.

Hopefully by next weekend I'll have some frost on the 1st stage!


Cheers,

Rich.

First ever phase unit? And going to cascade? I wish you luck sir!

[bazx]

he has a fair bit of back up adam

good start barron cant wait to see ya benching with this

28cc rotary.. Christ. Makes American 110v rotaries feel quite inferior

[tiborrr]

I was about to say never to take on cascade on your first ever phase change build, but since you have such a great guidance from Benchtec boys (i guess bazx, SoddemFX, sacha35, ...) you will very likely do a great job.

Just remember not to be afraid to ask anything, understanding of basic principals of vapor phase change is crucial!

Best regards & best of luck!

Thanks for the comments guys.

I know I should really have started with a Single Stage, but Im never one for doing things by halfs!

I have had loads of help and encouragement from some very talanted guys, Baz, Sacha, Tom and Dulist. But the numero uno of helping me out and putting up with my constant silly questions has gotta be EvoCarlos, he a top bloke and without his help this would never have got started

[Ozzfest05]

I want that condenser looks excellent in black

[runmc]

With the mentors you have, I'm sure you will have a great build. Please don't leave out any details.

[QuantumZero]

hmm about time i should build one too.

[before]

Maybe, I'm not a good example; dunno really... but I started by building a 2-stager too.
No need to do a single-stage first (not cold enough IMHO, it doesn't worth the effort), it's all depends on how you are approaching the job.
Take care.

A small update to todays progress

Built the HX enclosure





Painted the Case, this is not a very good pic, looks better in the flesh




Picked up a TS2 expansion Valve from RPW today



Also had a delivery from the nice people at BES

[runmc]

What size orifice did you get for the TXV? What number?

[Baron_Greenback]

Its a 01 size orifice mate, it may turn out to be too big and I'll need the 00

First unit being a cascade... you sir are my new Hero... Screw batman or superman... Your it!

[TheKarmakazi]

Good luck with your first build! Looks like its progressing nicely

+1

good luck, going to be watching this one progress

[Baron_Greenback]

Another small update. Condencer now refitted and bolted down, 1st stage comp also bolted down. 2nd Stage positioned. Hopefully i'll have some frost on the 1st stage by tomorrow nght!


Space is gonna be tight when its all in there me thinks







"Unseen" controller from my old single stage. Im planning to use this to control the cascade. It has 2x 16A relays I can use to power on the 2nd stage when the HX reaches the right temp




All for now.

[Baron_Greenback]

OMG what a day... After getting banished from my dads garage due to his "safety concerns" I headed over to Carls for a couple of hours to use his workshop services

13 hours later, and this is what we have....


Begining to look more like it...





HX braised and installed into its box



HX box, TXV, Filter and Sight glass installed and braised up



Pressure tested to 20BAR and Tripple evaced



After 2 hours under Vac green is for go!



First frost! I have a lob-on



Some temps and pressures, un-lagged and gassed with R404

[Baron_Greenback]

At last, an update :biggrin:

After dragging my arse for 3 weeks, I finally got around to buying an Oil sep yesterday. So the next logical step was for us to spend till 3am building the 2nd stage, I did hope to have this finished lastnight (this morning!) but the after effects of 8 cans of redbull were not pleasent

Some pics of the nights progress....



Controversial desuperheater mounting. This shouldn't matter as there will be no liquid in the pipes at this stage, just gas.





mmmmm.... sexy




Maybe further updates later.

[runmc]

Mr Greenback - your black box is shrinking BRAVO Looking good

[before]

Great work so far.

[[XC] gomeler]

Looks great. That DSH position should be fine as it's post oil-separator. I'm sure a little oil will escape the oil separator but it should eventually travel back. Looking incredibly clean for a first build

[Baron_Greenback]

Another update

Gauges ready for mounting...



2nd stage pipework now complete!


















And thats how shes stands now

A HUGE thanks must goto Carl for all his help with this unit, I couldn't have done it without you m8 :biggrin:

[Baron_Greenback]

First frost on the Evap!

Only running Co2 at the moment, so temps not great, but it works...
