Hi

I want to show You mine latest cascade, it's 2 stager based on 2 rotary compressors, plate HX, Danfoss TS2 valve, Danfoss OUB1 oilseparator, some extras like four REFCO panel gauges or dixell controller and .... metal, BLACK case . We like that kind of cases, do we ?

Specs :

compressors: two Sanyo C-1RV137H11AA rotaries
evap: steeper by piotres
XV: Danfoss TS2 / captube 0.8 mm
HX: plate HX , 12 plates
condenser: 2 row, alu-cu, cooled by 4 x 120mm/12 V NBM fans
refrigerants : R507/R1150
oilseparator : Danfoss OUB1
safety : cut-off
case : metal case, 46 x 46 x 43 cm, black paint
others: 4*REFCO panel gauges, Dixell XR10C controller (turn on 2nd stage automatically when 1st stage is enought cold), homemade receiver before Danfoss TS2, big 230 mm/230V fan on the back wall of case









Suction line is braided one, 18 mm thick insulation and red sleeve .



Sorry for some dirty old insulation on compressors' accumulators .







Finally I've add shock absorber to 1st stage suction line (called "anaconda" here in Poland ) and add also second drier to 2nd stage .





Some first run digits.











Final charge, no load .



And here loaded with 225W.







We have tested that cascade on E6700 till now, and we got around -98-99*C loaded, and -100-102*C idle on evaporator with 4.7 GHZ / 1.7 V (end of bios in stock asus P5B DLX : ) .

I hope You like that project .

Thanks
Regards
Peter

I have the impression that your former cascade gave better temp' with load... No ?

Compressors are around 9000 BTU.

Time - I think around 50 hours of work, but I have never measured that .

Yes, previous ones have been making around 2*C colder I think, maybe that's becasue of another HX ? (there - homemade (+SLHX in one cascade), here is plate HX) .

Thanks
Peter

Hello

Sorry for diging, I just want to say that those cascade has been tested on QX6700 and QX6850 and on both it's making sth around that in idle :



And in max stress during SP2004 around -94*C .

All these temperatures during OC - around 4.5 ghz , over 1.7V .
