One for the fridgies

We have used r407c quite a lot,using the additive in some systems,and in others that already have a compresser with synthetic oil,just using it replacing the R22.

Never had any real worries except for a couple of Copeland scrolls in AC systems.
I also now know others that have had the same issues,with Mitsubishi and Daikin scrolls as well.

We do have a site with 5 cold rooms,and a couple of huge cabinet systems,with numerous evaporaters,all on R407c,and no issues.That site is probably 20 yrs old.

Who'd've thought a urine extracting post could draw nearly two dozen serious responses? [bighmmm] [bigrolf]

Paul, it probably had probably been correctly installed with care & had Pipe U Bend Oil Traps installed especially if under floor piping was involved.

I thought you would've learnt by now that any opportunity for a fridgey to wax lyrical on something technical is unavoidable! [emoji23]

Nearly all Copeland Semi's.
15 of them are knocking or rattling,or shaking.[bighmmm][biggrin]

And thats just the start[biggrin]

Sounds like you'll be buying a new Maserati or two?[bigrolf]

In that Vac Pump image, it appears like there are a couple of semi- Naked women through that doorway.


Knocking Shop was it?[bighmmm] Go on say it Paul,
"Can't say I noticed as I was going like a cat ****ting razor Blades trying to get that ****ing Pump working." Of course you were.
