Repaired units (Prometeia + 2x LD unit)

[piotres]

Hello

Last time I've repaired 3 units :

-small LD unit based on NL11F
-Mach 2 GT in custom alu-frame housing
-"big" LD unit based on rotary.

All units from one Denmark owner. Owner of units supply me some parts needed for mods + I make new suction lines with new evaps.

Owner do not want any visual mods of units, just to make them working again.


BIG SS:
-new 110cm long suction line by me , evaporator 54mm
-mounting second conder (supplied by owner of unit)
-chaning compressor to brand new LG 14.3k BTU
-R507


Prometeia Mach 2 GT:
-changing suction line to new, 42mm evaporator
-R507
-new pipes and drier


Small LD unit:
-new suction line by me,42mm evaporator
-R507
-new drier

Rotary compressor from big LD unit have been "dead" as owner said before work, but I have checked it and it work fine .

So I make 4th unit basing on that compressor + black ECO condenser supplied by owner + one of old LD's suction line (check it for leaks + redone insulation). Those will be new GPU unit .


Final results (unloaded and loaded temperatures) :



Nice box for transport DK->PL .



Brand new LG NJ282PAD for big unit.





Some shiny and red stuff made by me .





Big unit done. Result @315W.





Small LD unit done. Result @280W.





And Mach 2 done . Result @280W.













4th unit based on parts which left from mods + "spare" condenser. Result @315W.



And all ready to go PL->DK .

Regards
Peter

Nice work Peter as usual !!!

Man that Evap is a monster !!!

[Riska]

Looking great Peter cant wait to get them home from my Work and my team buddies is calling all the time to hear when they can pick up there SS

[sdumper]

Looking shweet like always...

[nachtfalke]

very nice clean build here

one tipo the LG NJ282PAD - is a 17000BTU compressor

[Riska]

No it is not acording to LG it is a 14.300 btu i have the datasheet pdf on my pc somewhere from LG

I have looked around on different lg sites and some have it as a 14.300-14.400btu and some have at 16.800-17.000btu weird?

[Moc]

I attached the datasheet, have a look.

[nachtfalke]

it is 100% 17K btu compressor

LG NJ236PAD (14,3k btu) has same datasheet specs compared with Moc datasheet for NJ282PAD lg mistake
take a look

[wdrzal]

The BTU rating depends on the evap temperature plus quit a few other parameters. But one diagram above shows -10c to 12c. evaporating temp, that's 22 degrees c. of swing ,that right there changes the BTU rating for the same compressor.

[Moc]

Yeah nachtfalk, I checked another LG pdf an your right . Und wo ich sehe das du aus Deutschland kommst, bist du auf extremecooling angemeldet? Falls ja dann verrat mir doch dein Usernamen dort ^^ .
@walt
Yeah, displacement is a much better value for comparison.

hey fokes a little update from Denmark

my good friend and team mate riska got a nice package

it arrived in good condition Thursday





very firmly wrapped!







very very firmly wrapped !





riska . Lynmazda and me "gorgy_dk" met Saturday
for testing and do the last little things that we persuaded Peter to make ourself.

first test if they had survived the transport from Poland to Denmark ok.

"big" LD unit based on rotary.





Mach 2 GT in custom alu-frame housing with much bigger condensor.
4th unit basing on that compressor + black ECO condenser supplied by riska + one of old LD's suction line.





we started to make the finishing touch on the small LD unit based on NL11F





opning the unit up to mount LED Displays and new probe inside the suction line

LED display with PT100 probe 12V 12$ at EBay
not as accurate and fine as the measuring probes Peter had mounted but they are also just to see if the unite is cold enough to start up the system.





we also mounted transport handle from kitchen doors.





a small power supply from 220v to 12v 2A are significantly designed to tow LED strips "8$ on Ebay"






we glued insulation joints with liquid tape to make it stronger.









we have tested all SS units with standard temp gauges and all the temprature as Peter also had stated
but as you can see is the $ 12 meters is not quite so accurate it shows approx. - 2 gradre less





put it up to the reality test






Asus p67 sandybrigde 2700K 5480 mhz 1.6V
3 degrees of difference between desktop and in 3D 06 CPU test full load ...... Nice !!!


then it's time for Coffee


Today's next project Mach 2 GT in custom alu-frame housing

Peter started the time with something shiny red stuf from me

we take the shiny red stuf a littel further


1 mm aluminum front panel mounted with double sided tape




1 mm aluminum top plate with bonded 10mm PVC plate that fits inside the frame to avoid resonans




we used a 51 mm hole saw to drill out for the Evap





in the front we have installed 2x Led Display 1 to Evab and 1 For compressor + adjustable 220V power to the front fan.





The prope on the Led display for Evab is - 6 degree lower than Peters Prope mount but I Know - 34.2 is actually - 40.2 Degree

we mounted transport handle from kitchen doors





and the same 12V power supply to the Led display and here we mounted Also Led Strips in the frame

rear view here we mounted on off to Led strips
and we have on off mounted just above the line to the SS unite






The side panels are made of 3 mm milky white Plexiglas





my camara does not like to take pictures of red Led the lights too bright but here is a fairly image edges are red in reality the question they do not light up white





The final shot





And ready for Benching ;-)

we had spent a day! we fine tune the 2 large units another day

Hope you Like IT..

Thanks To Peter for A greate job don

[Buckeye]

That looks very cool Peter !

Nice work as usual and something different !

[Ace123]

man... how much does it cost to make a unit like this?

[Riska]

It depends on wich unit you want?

and if the unit should be all new or an old one refurbished.

[Ace123]

I would want one that just plain works, I dont care what it looks like or the age of the components as long as it functions correctly.

[Riska]

Give piotres a mail and he will have prices for you they are not wildly expensive
