Damn it must be such a nightmare building a cascade like that, and then finding you have problems and it needs taking apart.

it is a pain for sureOriginally Posted by Brettbeck
well got the unit working and stable after fitting the new temprite 900 oil sep gased the 2nd with R507 and ran it for an hour just to make sure all the oil had returned back to the compressor
then vaced it down and regased with R23
just had the unit running for 2 hours without load on the evap just to make sure that all temps and pressures would sit stable before i moved it over to the bench
and hooked it up to the QX6700
load testing tomorrow now
some picks

Isn't that a 25litre dewar? I could swear I saw that on eBay a while ago!
Rofl at some of those pictures baz, I liked the saussage roll experiment!
Great work, build it not only functional but make it look NOT like a crows nest and build it safe,all stages that require safety devices, You and your customer will both sleep better at night. Sign your work as a painter signs his creations. Be proud of a job well done.
