Been kinda absent from here lately as I was sent to Chile on the 2nd Jan and will stay here till the middle of march. supervising the Installation of a pump circulated freezing plant on a japanese owned trawler.
anyways, Today, as I was walking around on the factory deck, I noticed that there were some local fridgies working on a Trio skinning machine (It's a machine where they freeze the skin of the fish to a roll, to pull it off).
I had given the machines a gaze a week earlier after they had pulled the compressor, just to see how it worked (curious as always :)).
Back to the story:
They were soldering some copper pipes, so thinking that I might be able to give them some advise :D I stood idely by, waiting for my moment to chip in, sadly, they knew what they were doing and my superior knowledge was not needed... So seeing that, I walked on and found someone else to watch... incase they needed my knowledge :D
when I returned to the Trio machine they were in the process of pressure testing... they had obviously allready charged the system cause they were going over it with soap and water... then I noticed the N2 bottle, my spinchter puckered and I made a hasty retreat to the upper deck to not venture back into the factory area for another two hours...

Thats a 200 bar N2 bottle connected with directly to a 1/4" yellowjacket hose... there was a danfoss BML valve and then another hose connected to the machine.
I cant remember the burst pressure of the yellowjacket hoses, but I believe it's 3-400 PSI or maybe that was the working pressure... cant say I wanted to venture close enough to have a look
