Danfoss SC18CLs GPU SLI/CF Cascade - worklog

[piotres]

Hello

It's mine first SLI cascade, some mounths ago I have tried to make dual-evap one, but it didn't work fine becasue of too small condensor . This one has quite big condensor - dual fan 200mm each 230V, 3.6 kW condensor . Cascade will be using silent Danfoss SC18CL compressors and of course oilseparator with float. Adds like Dixell controller and 4 REFCO gauges kit started to be "normal" in mine cascades - everybody want that . Cascade will be using R507 on 1st stage and R23 on 2nd stage.

Specs :

compressors: 2 x Danfoss SC18CL
evaps and suction flex hoses: two GPU evaps : steeper design, 24mm tall, 42 mm diam., plus 120 cm long suction lines DN10 braided
XV: probably Danfoss TS2 on 1st stage/ captubes 0.9 mm on 2nd stage
HX: Plate HX, 12 plates
condenser: 3.6 kW condensor + 2x 200mm, 230V fans
refrigerants : R507/R23
oilseparator : Shine Year with automatic oil back
safety : Danfoss KP5 cutoff
case : Laser cutted and powder coated case (white) plus black details, wheels
others: Dixell XR20CX to control 2nd stage start, 4* REFCO panel gauges, expansion tank 1.1l Torecilla, two white CCFLs inside, 350 mm 230V blower fan on back wall.


It's worklog, now I've got bit longer break in work over it, becasue of problems with getting case for it, one workshop make me that since 5 weeks so change it finally for another, becasue I don't like if somebody threats me in that way . I hope case will finally arrive to me next week .

Case will be BIG one, with 350 mm blower fan . Case will be white with black details .










Two GPU evaps after final cleaning .









Big condensor and rest of parts .




That's 350 mm fan .



Condensor which I've parted for desuperheater for 2nd stage and condensor for 1st stage .



REFCO Gauges and Danfoss KP5 cut-off.



I've new googles , special designed for acet-oxy brazing - Nemesis IRUV 5 .





Suction lines .





1.1 l Torecilla receiver modded to expansion tank.

More pics during few next weeks ...

I am jealous over that condenser. I want something like that so badly Looks like it'll be a slick casacde, will be interested in your cap-tube tuning.

looking good piotres, but what 'bout those googles?

[runmc]

Amazing work!!

[Duniek]

nice outfit for work lol

[Polizei]

Top part of the condenser is a desuperheater for second stage?

Nice shades.

[DagoDuck]

Really nice parts m8, I like the gauges and the huge condensor. Are you using propane as inert gas?

[sacha35]

Very Nice work as allways piotres.

I'm always so jealous of the condensers, the damn condensers

[yngndrw]

Awesome job so far.

How did you unbraze them U bends in the condenser so neatly without marking the shroud ? :o

Hi,

I've added description to 1st post.

nice outfit for work lol

You want to say that mine jacket which I payed 15 eur looks funny ? .

looking good piotres, but what 'bout those googles?

They're Nemesis IRUV5 , specially designed glasses for brazing jobs. That flux from silver rods makes very bright light (You know that ), so it's nice to have secure eyewear .

Top part of the condenser is a desuperheater for second stage?

Nice shades.

Yes, it's desuperheater .

Thanks .

Yes, propane .

Awesome job so far.

You know ...some skills is needed hehe . Nah, just a joke , just use wet cloth to cool shroud properly, and don't heat pipes too much .

Thanks for all nice words .

With Kindest Regards,
Peter

Well done Peter! You're work is always top notch! I can't wait to get my suction lines in and see this craftsmanship first hand. Keep up the diligence and I’ll be studying this thread carefully. Cheers!

Looks good Peter.

I think he means that your jacket is synthetic and it can easily ignite. its not so safe.

PS Good and clear work!
Are the evaps nickelized?

[piotres]

Are the evaps nickelized?

No, naked cooper .

piotres, can you tell me therough dimensions of the condensor?
also fine would be the over-all tubing length of the condensor.

i have a very similar one and i dont know the condensing power of it, so i would like to compare.

your are doing a good work, i am looking forward to the piping job

Hello Pawel

Not "too" cold becasue of R23 in 2nd stage, but sth like -60-70*C on each head loaded with over 200W is mine goal .

[sobih25]

it sounds quite good imo .
