Re: R600a
Been working with R600a for many years. Worked for a major manufacturer in the UK and Italy and was part of the team that brought the gas into the UK from Bosch via my prev company in Milan in the mid 1990's. I am still in the trade and find Beko give the most problems with R600a due to blown valve's on the cheap pots.You usually find the condenser is full of oil because of this. We normally change the pots and condensers at the same time as we repair in customers houses and don't blow through systems. Never had any problems with capillary blockage. We only ever use lokrings and dont tend to have problems with them. R600a has a really bad scrubbing action and when I was testing systems in the lab in the mid 1990's we found that copper oxide from brazing was rubbing off and entering the capillary. Lokrings are a cleaner system and you don't get the risk of copper oxide contamination. Wouldn't recommend using R134a in a R600a system as the oil will eventually wax and block the system

Re: R600a
I am thinking of doing this also, so will be waiting to here how you find it. Thanks jim

Re: R600a
we have loads of 600 problems mainly with blocked caps and blown comps useually down to blocked condensors we find the biggest fault is a very low back pressure we had to do a specialistcourse due to our insurance every week we do a walls freezer with one of the flammables in fitting comps and caps

Re: R600a
No one has mentioned what to do when you get a blocked cap tube!!!

Re: R600a
Either try to flush it out or replace.

Re: R600a
Hi friends.can somebody help me?
how much is the capillary tube in refrigerator when you use R600a?
How you can calculate it?

Re: R600a
and another question.what is dynamic viscosity for R134a and R600a?
thanks alot

Re: R600a
Hi All
I have been working on and with R600a for the past 14 years approx. and compared to R134a or any other drop in's its the best refrigerant available.Restriction's probably be able to count them on my fingers if I could remember the last one I had. Scales.. Don't use them and you don't need them if you get to know the working pressures.If you charge to -.450 on your R600a single gauge then you will find its a perfect charge.
Concerning ventilation.All you need is what you would expect to have doing any refrigeration work.I have brazed from the very first time and will continue to do so. Approx. 5000 compressors so far and no failures due to the refrigerant.If you use a cheap compressor then you get what you pay for.I refuse to fit anything other than aspera/whirlpool compressors for domestic equipment.
