Naked, 2x 1HP cascade

[piotres]

Hello

I move this cascade from this topic : http://www.xtremesystems.org/forums/...=166418&page=3, becasue this contest finished .

This is quite ordinary cascade - metal baseplate, plate HX, R507/R1150, 4 gauges ...but it finally have 2x 12000 BTU,1HP compressors, not ordinary for me 9000-11000 BTU .

Specs :

compressors: Sanyo remark C-RN110H5A around 12000 BTU so 1HP on both stages
evap: steeper
XVes: ALCO TI-HW (designed for R22, but I bet it'll be working well with R507) + nozzle 01 / captube 0.9 mm
HX: plate HX , 12 plates
condenser: 3.0 Kw, alu-cu, cooled by 300mm/230V fan
refrigerants : R507/R1150
oilseparator : Shine Year automatic
safety : JOHNSON CONTROLS cut-off, 1.8 litre TORRECILLA expansion tank
case : baseplate 46 x 46 cm, zincked steel + wheels
others: 4*REFCO gauges, Anaconda shocks absorber on 1st stage's suction line,DIXELL XR20CX controller (turn on 2nd stage automatically when 1st stage is enought cold) .







Baseplate is ready .





Braided suction line and compressors,which I planned to use first .

















Suction line ... green sleeve finally arrived yesterday, I'll put it on suction flex hose soon .







TORRECILLA 1.8L receiver will be modded to expansion tank .

Then ...

I've decided to use 12000 BTU 1HP compressor in both stages :



and more work ...





Finally, I've put wooden plate under steel plate to make it more stiff - those 1HP rotaries aren't light ;-) .



















Temperatures during filling,no loaded, with almost no insulation (except that which You can see so on suction line and on HX) .

I've already almost made complete insulation, in next few days I'll made electrics and final tests on new 260W dummyload which is already waiting for frost .
