Hello

Want to show You a work which I done in 2018 :) . Sorry for not good pictures, using iphone 5s to make photos in dark workshop wasn't good idea.

1. Cascade to Belgium, 18kBTU + 12kBTU , bartx 65mm diam evap, R507/R1150, gauges, automatic oilseparator.

-86C@400W

-80C@550W

3. Repair a suction line leak +refill of 2nd stage of cascade from Austria (not built by me), two R134a rotaries looks like approx 8-10k BTU (do not check specs) , unknown evap diameter under 40mm, R404a/R1150.

Before it caught a leak it was running with R23, do not have problems after R1150 regas.

-103C no load

-90C@250W (cascade is approx 10 years old and were build to hold load approx 250W, mine work was only to repair a leak and refill it so I do not test it with bigger loads).  It should handle 300-350W.

Amazing work! Are there any good phase change builders in the USA?

Don't think he participates here though.

I can get his info if you'd like. Probably better to inquire for yourself at Overclockers.com though. He hangs there.
