its not the boiling point that counts, its how good the gas will take the load.

if im right not sure R507 is best, then R410a :).

JOOOOOORT where the hell are u :p.

I use it as a reference :)
Who needs Jort when i have a better cooltechnician at house :D

Made a few system changes, smaller desuperheater as in less loops, i added an extra pipe to the suction line, insulated the whole part as well, i've changed the oil so my system now can run either R507 or R410a, it's going to be R410a (no R507a avaible) and now my system is in a vacuum . When it's done i will be charging the system again and have a test :D

someone is calling my name ?

R410 isn't the right coolant, you better use R507 ;) of R290 aka propane. Very cheap and environment friendly.

evap can be made quite easy with copper cap in cap design and a 0,5cm baseplate.

grtz

Is there anyone in Belgium that can have a look at my Phase unit... I'm really suspecting something is going wrong with it...

what do you suspect ?

i no longer have any equipment at all to repair it if needed...

The R410a goes well at the moment , hitting -53°c idle . Still need a dam load tester :/ I wanne see how it succeds or fails :D

R410 is an high pressure coolant, mainly used for airco ;)

It will let your compressor work pritty hard :D

It's a l'uniti hermetique 1/2hp compressor, it must work hard :D

No serious it's the best refrigant i have at the moment, this unit also only counts as an test object. My final unit wil be with R507 :)

Btw i didn't knew you already picked up the dewar long time ago? :D

*edit*
Btw back in those days, how did you declare the cappilair? size and lenght?

It seems to no longer hold high loads... I used to be able to maintain 5.6Ghz easy with the E8600, now it's only 5.2Ghz... same for the S478 CPU's, Unit whistles all the time when the CPU goes under stress... Blind suspects a small leakage in the flex...
