Silver Cascade (2 x 1 HP) with bypass valve

[piotres]

Hi

One more cascade with two C-1RN110H5A compressors (1 HP each one) . This time unit is cased, case is powdercoated (color weissaluminium), condensor is big one - 4.8 kW with 2 x 254 mm fans 230V powered. First time I've used bypass valve (made from Castel 1/4' valve) - to make evap's temperature bit higher if that's needed . Rest is "standart" .

Specs :

compressors: 2 x C-1RN110H5A
evap: steeper
XV: ALCO TI-HW / captube 0.9 mm
HX: plate HX , 12 plates
condenser: 4.8 Kw, alu-cu, cooled by 2x 254mm/230V fan
refrigerants : R507/R1150
oilseparator : Shine Year automatic
safety : Johnson controls cut-off, Fach 1.5l expansion tank
case : Laser cutted and powder coated case (weissaluminium) 69 x 69 x 54 cm, wheels
others: Bypass valve - Castel handvalve, 4*REFCO panel gauges, ANACONDA shocks absorber on 1st stage suction line, Dixell XR20CX controller (turn on 2nd stage automatically when 1st stage is enought cold), black coated pipes, 350mm fan on back wall, cork sound insulation.

Cascade isn't finished already ...








Case isn't naked from inside .









Knob's fitting .



Bypass is veeery simple but I hope it'll be working .















In 5*C workshop without insulation...



Loaded @260W first try .



Leak detectors which I've used (not all 3 in same places of course ) . I can say Wigam's is the best, also Amasan is very good (not on this photo) .







Big fat insulation on 1st stage .

Will be continued ...

With Kindest Regards
