frozen cascade

[kayl]

Time to do another cascade for some wolfdale benching

2x 1.5hp Rotary compressors, r404a as the first stage refrigerant cooling a 12 plate HX feed via dual capillary.
For the second stage ill use ethylene with a shot of propane to aid in oil return.
I will use hot gas bypass with an electronic solenoid to battle the cold bug and also use a accumulator as an expansion tank to reduce the over all static pressure a little


here I have the same condenser used in my last cascade lined up against the new condenser, they say bigger is better




The electronic solenoid and the thermostat ill use to start the second stage at desired temperature
