Resurrection of a CFEI 100 KVA Induction Furnace
awemawson:
However I find that I have:
A/ Two sets of four hoses - a long set and a short set. At a first glance they look as though they may have survived
B/ A spare coil unit for the crucible unit - looks OK now I've removed the mouse nest !
C/ The big Grundfos pump that I used to circulate water round a 'Cold Bank' (a standard copper hot cylinder) - this may be OK - I had been careful to fill it with water to keep the seal moist and cover it with the small plastic header tank to keep the rain off the motor)
D/ Two tubs of high temperature cement - may or may not be OK
E/ Miscellaneous water fittings
F/ Furnace driver four way pipe 90 degree adaptor
The ends of the chilled water hoses can be re-used so they are not a total write off.
So next I need to do a proper assessment of the driver hoses for electrical conductivity and water tightness.
awemawson:
Inspecting the short driver hoses they are quite badly crazed but although I'll not use them ultimately with water under pressure, they will be OK for the 'pinging test' I think
The long set of hoses actually seem to have fared better - I've not completely unwound them but the bit's I've bent so far don't show the same crazing. This long set of hoses I made myself from brand new welding cable and 150 PSI 'Brewers Hose' so is probably a bit newer.
I'd forgotten that I also had a rigid set of extensions I'd made - heavy wall 3/4" copper pipe double insulated by two layers of flexible conduit which was a right pain all those years ago getting it on!
awemawson:
I had words with a local refrigeration company today - (I've used them before re-gassing an air drier compressor so had one of the directors mobile number on my list ! )
Basically his conclusion is much the same as mine - the compressor is toast, the rest of the plumbing is questionable, and even given an (expensive) replacement compressor it will use gas that is no longer allowed :bang:
. . .so it looks like a replacement total water chiller is the only logical way to go if the ping test works.
Meanwhile I re-palatalised all the ancillaries making sure the pipes needed for the ping test are on top and tucked them away in the tractor shed. Now if I'd had the tractor shed before they wouldn't have deteriorated - but I didn't :bang:

Sorry to hear that mate.
Cheers, Matthew

Will it work with total loss cooling using water form your stream , I know it's 70 yards away but 150 yards of hose have to be less than a new chiller ?
