One for the fridgies

Yep, there's three grades of nitro, and most everyone just uses the industrial grade.
The high purity stuff is the go. [emoji6]

In another life,when I did many years of commissioning, apart from leaks,moisture was the biggest issue with trying to get good vacuums.We used to purge every largish system with a full large bottle of medical grade dry nitro, before starting.Had heaps of success doing this.The suppliers of the standard dry nitrogen could not guarantee it was dry.The medical grade always sorted out the issue.

Des,what I recon they did is turned the switch to the fans off,its pretty easily accessible on that particular room, then set the spoons up.We also found a heap of spoons in the condensate tray,so I recon they have had a few goes at doing it before being successful.The fans are standard 300mm,the spoon will slide up through the guard and jam it, pretty easy to do, once you work it out and they have the luxury of having all day to work these sorts of things out.[bighmmm]
Its a bit of a change from setting off the fire system by breaking a sprinkler head or punching an entrapment alarm in, just as they all head up to their bedroom suites.[bighmmm]

At the youth centre,breaking a sprinkler head sets off the deluge systems, it floods the whole block, an absolute PITA,as it wrecks the whole place.[bigsad]
They are starting to modify this system so it can only be manually turned on by a staff member.

It is time then that they got some overpaid & overstuffed engineering type to rectify those things then, S'funny you know, I have never once used my idle time to jam fans in a Coolroom. Me odd? Not really, I come on here instead.[biggrin][biggrin]

Maybe I am not of the Criminal bent.:Rolling:

I'm trying to find a photo of what happens when you have three fridgey's on one job.

Someone that is constantly whingeing about the lack of repeatability with vacstats had a bright idea while pulling down a high wall.
We ended up with about five to see where they all ended up.[emoji16]

We got one, its fine.
We worked out the new vac pump we have pulls down to 150microns,as per its specs, and the gauge sits at 150,so all good[bigrolf]

It is hardly ever used these days, probably because not only do we have no need to,we sort of don't trust it.[bighmmm]

The ones we used years ago were all analogue, seemed to work well.[biggrin]

Really stretching my memory,and maybe dreaming, but I am sure we had a couple with mercury in them?

Rick on the roight. Calling Boss to locate the nearest working Vac Stat & finding it in the local Coffee Bar in Byron. "Be there in 5 Boss wearing my nice new Manager's shirt."[biggrin]
