R410A-Cooler

[cold_ice]

I built a unit with a big Rotary for R410A yesterday. Will charge it with R410A today, when there are no leaks.
Parts used:
LG GK151P R-410A
0,67kw condenser
1m DN12 Suction line
0,9mm captube

r410 sounds like a real good gas,

have u used it befor?

what kind of temps do you get?

bp is -61c should get some really good temps!!

look clean and sweet!!

[aussie_guy00000]

yes, gives good temps at 0psig (-52c/-61.6f), but condensing pressures are pretty high, 432psig at 50c/122f, steps up to 543psig at 60c/140f . Best make sure those brazed joints are good and that fan is crankin , have to make sure your gauges are rated for it too.

This is a system to my likeing

That's one big condensor!
but combined with that compressor and refrigerant, it should perform really nice

I don't think that condensor gets 50*C. the condensor is rated at 670watt which is often with a deltaT of 15K, so I think the condensor will remain below 40*C.

I think it will kick ass...

Pics arent wroking but are you using an SLHX?

No, He isn't

[n00b 0f l337]

Can you repost pics elsewhere?

[kommando]

Pics are fine here.

Thats a rockin' setup though.

[Moonman]

Looking good.
Load eater.

[n00b 0f l337]

Pics working.
Holy shiznat that is a beastie.

[LittleDevil]

Really nice unit... What about temps?

tnx

It may remain below 40c where you are, but ambient temps here are often 35-45 so it's something that I always think of , and so should the guys who make and sell units to people in other parts of the world where ambient conditions could be quite different to where they're manufactured. Nice system but, very neat and professional looking .

Had not much time today, but I was able to do the elctronics and fire it up for some minutes. The unit is awesome. Tomorrow load test with 180w.

ahha that frost is nice- good luck insulating o_O

how many cfm is that 220v fan?

and the brazing on the evap is amazingly clean. nice job

[eshbach]

this is a great little unit cold_ice.

you are making quite a name for yourself here, keep it up

[[XC] MarioMaster]

I wish I could get some nice condensors, they are surprisingly hard to find

[the_new_guy]

how hot does that compressor run?

amazing unit!!

[epion2985]

Damn, looking good

[Something Sexy]

I want that fan...very sexy.

[aussie_guy00000]

I have condensors very similar with 240v fan attached, but the core design is a tubeless design and suppose to be more efficent. The one I use which looks to be a similar size is rated at 740w. Tehy work very good . Good work Cold_Ice, it's some seriously cool looking SS

[piotres]

That frost looks nice

Cold_ice, please check discharge pressures with R410a, without load and when unit is loaded

Thanks

Regards
Peter

[cold_ice]

Without load it was about 15bar, will check with load when I have time.

Wait a sec? supco = refco? I have exact same looking vacuum gauge with supco vg-64 and it is blue????
