The Kryotech Americold compressor is a low RPM/Quiet compressor. I dont think it performs as well as the Danfoss. I got a 404a one too at work.

Fugger,
im in the middle of tunning a mach1 from 134 to 507,
but i have a problem with the temp sensors....
when i get down to -55
the display goes er0 and er5,
i got rid of the er5 by setting it down to -65, but
er0 is still in the display not alowing me to see the temp,
so plz, tell me what to do.
:confused:
You have to ignore it and push the reset button on the Mach1 when the alarm sounds.
I will take the time to find that damn buzzer this weekend and upload some pics on how to disable it.
is it possible to "kill" the "er0" so that i will se the temp insted ? , i dont give a f-word about any "error's" =) its not my rig, and the dude that ownes it is 5200 Km away from where i live. but lets hope he doesnt read this post anyway,
i would be wery happy if you could help me out on this one, i know the refrigeration-system but the electrical is as fun as it can get... not...
will post some pic's soon if the owner alows it =)
Chilly1 is working on moving the sensor back to measure the superheat instead of the evap head. This would stop the error mode. But the peson who owns the mach would have to understand where they are reading temp from and it will never get to error mode again.
Hi Fugger,woud compressor made for r404,r507 withstand the pressure of r410?
Yes, I am running R410 in a compressor made for R404/507
SC12MLX likes the R410, no start/restart problems experainced so far.
Intresting reading !
Nice FUGGER ;)
I will do the r404a mod to my prometeia mach 1.. I will go to my local AC store and do it. How much should i lengthen the cap tube for best load temps ? Any thing else to think about ?
i read everything dude:D , and asu said, i dont give a XXXX about the errors, just nice numbers:toast: Hope u solve this mr TQuote:

Yes and i alow it, post some nice pics:p:
Thanks Fugger,must i change capilary going from r404 to r410?
How much space shoud it be ,betwene end of capilary and botton of evap(2,3mm)?

I did not extend the cap tube, just a straight charge of R507 and some tuning.
I had to reset the alarm temp to -65c
I can reach 4.2Ghz on stock voltage and boot into windows. I might be able to reach 4.3Ghz on stock voltage.
Less than stock voltage @ 4Ghz running PCMark.

Running 3D my MachI display will warm up to -51c
My compressor maxes around 115c so I know enough refridgerant is getting back to the compressor.
No start problems at all and no popping oil.
My only problem is my display reads Er0 from one minute after I turn the unit on till I turn it off.
This by far beats 134a badly.
Benchmarks this weekend
so when can we mod mine?
JB, whenever you are ready. I got gas
I used existing cap tube (approx 10 feet didnt measure)
and charged the system accordingly.
You don't need to change the cap tube length... You charge accordingly. For r410 there is the need to use a hydrocarbon refrigerant additive to the system to keep oil from causing problems. R410 needs polyolester oil which 404/507 compressors use. It is all a matter of balance. The prometeia units I have modded the head pressure under P4 laod is only 195 psi.
nice work fugger... wanted to change the gas on mine forever, but dont want to have to extend the tubing.. unless of core the A/C company can do everything for me...
wonder how much they would charge
I had my machII filled with r507 a while ago, but temps are not on the good side all the time.
I think there just isnt enough of it, the compressor seems to have a lack of power, so i think there just aint enough of r507 in it...
i would like to have it refilled, but what would be the best way?
1) Have the 'old' r507 removed and refill it with exactely enough new refrigant.
2) Let some A/C company refill it in small steps, like per gram till it should be enough?
-> I really have no idea how much of r507 they have put in it and if its even real r507 (i know, dont tell)
so how much of the r507 should i put in then? (total)
When you have a tech refill your unit, evac it first and then wet charge it. turn it on and set it around 4 inches of vacuum. You should get plenty of cooling back to the compressor. pull it down to 6 inches and you will get a little colder and less cooling back to the compressor.
Dont forget to add a small amount of gas before you pull the hoses to compensate for the loss of removing the hose.
Once set, do not adjust the charge or put hoses back on unless you plan on refilling the unit.
Make sure the tech purges his lines and that he has the gauge calibrated to zero before you start so you will know exactly where zero is.
When you send in charge, do it in small bursts.
The R507 bottle should always be upside down when charging.
With no load the compressor should form ice under the suction line or be very cold. With a load the compressor will warm up some. Make sure you run with the side installed, you need the airflow across the compressor.
Fugger;
If i charge with r507 to my promme mach1 , do i need to have the fans on fullspeed all the time ?
