ECI 12+ (Single Stage Phase Cooler)

Another project on the bench, a nice quiet and small phase cooler.

Goals?
Low cost (~$600 or less)
Subzero (Around -20C or lower) load on an i7 sized load (or more!)
Small footprint
Solid (steel base frame)
Decently quiet
Low power consumption (Sub 300W)
Upgradeable features (Full case, digital temperature display)

Specifications:
1/5hp Copeland r404a compressor
120mm Chilly1 Blue Condenser with 38mm fan (~100cfm)
18" Braided flex line (Extrable flex, without risk of tearing!)
Copper Spiral Evaporator and new Universal Mount
Full Insulation kit
Double H frame, solid steel, MIG welded, ground, then painted

Pictures up in a few

Desuperheater coil brazed, as well as the main suction entity.


Steel triple H frame it seems, to help suspend the condenser. Might end up switching to 3/4 or even 1/2" steel. This 1" is way over the top.


I call this a Harvey Dent shot, one face is cleaned, one face still oxidized.


The bend of this flexible line, a steel corrugated line under copper/brass alloy braid. Able to withstand lots of pressure and still flex well.

An update!
Frame spot welded, ground, and heading for sand-land before some paint.

Single Stage sits on it, have some nice rubber feet as well.
Total drop in unit, solid frame, I love it.

Nice evaporator and mount ordered, took a bit of a while.
But should arrive this week so I can finish this up.
Oh and grinded and sprayed the frame!
Now to drill and mount some bolts and what not.

Mount arrives with evaporator!
Nice, universal, pre made insulation, what more could you want?

wish you lived closer i could uhmm......"inturn" with you / steal a guideing eye.
also subed on this one and the eci33+

Looks good so far! Glad it's a quiet one too. Crazy there aren't more replies in this thread.

Lineset brazed and pressure tested.

Custom accumulator brazed and fitted.
The internal design is NOT an empty cavity, but contains an item to cause baffling and stop linear flow.

I don't want to be a noob in your thread, but is that accumulator the thing thats usually filled with small balls and attached to the capillary line? I may need to make myself one of those.

No, thats the filter, and those balls are desicant.

The ice gods visited...

sexy

update?

It's a 1/5hp little unit, r404a compressor, copeland.
Chilly1 blue with 100cfm 110vac fan.
20" Flex line, Chilly1 evaporator, unmodified.

250W @ -26.5C
200W @ -30.5C
150W @ -35.4C

At 250W, 240psi high side, 30psi low.
The charge is primarily R402a.
Captube is .031" capillary tube, probably around 6ft right now.
Custom accumulator and SLHX.

Small format, and pictures of the base coming up later, nice steel framework with some paint. Size fits for drop into a V2000 if my measures are correct.

Compressors a bit warm at 33C, but overall not even that bad. Still producing very little noise, quieter then a NF9FX on r134a The noise is all in that fan, but it's needed for the moment with this kind of condenser.









Hope you enjoy.
