Hello everyone,

In fact it's my first serious unit. It took a lot of time to build this, but it wasn't wasted time ;)

Just an ordinary, quite strong SS. I'm pretty satisfied with the results (-41C @ 250W, -46C @ 180W, -54C @ idle). Maybe it can be tuned a little better (it also depends on where K-type probe is located, I've drilled small hole on the top of evap, bcoz for now I'm mostly interested in overclocking, not the lowest temperature ;) ). I've tested it few days ago, and on E8400 @ 5,2GHz 1,8v there was something like -48C what is nice ;)

Compressor - Teco KETC176 10755 btu
Condenser - 25x25x5cm, 4x 120x38 mm Nidec fans (10V, 0.5A each)
Suction line - 80 cm long, 19 mm thick insulation
Evap - stepper, 42 mm diam, 40 mm, my production
Expansion valve - 0,8 mm captube
Refrigerant - pure R507
Baseplate - stainless, 35x50 cm

Immaculate work Bart, and it looks like it performs well to boot. BTW, welcome to OCA, hope to see you around more.

4 fans on a single stage seems like a lot. Is it extra quiet.. or ultra low power or something?

I'd rather have those 4 fans with more contained static pressure than a huge Cessna prop blowing stuff off my desk lol.

What condensor are you using ?



what temp is the compressor running at ?

Thx everyone :cool3:

Fans originally are 12V 0.8A (kinda strong ;) ), but they're running at 10V 0.5A. Not so quiet, but rotary is still louder. Condenser is about 1kw, I don't know for sure. Compressor is running at 80-90C, I haven't measured exactly, but less than 100C for sure.
