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

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

Isn't that a 25litre dewar :p:? I could swear I saw that on eBay a while ago!
Rofl at some of those pictures baz, I liked the saussage roll experiment :D!
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.
