Resurrection of a CFEI 100 KVA Induction Furnace
Sea.dog:
I think we need to organise crowdfunding to keep this project rolling. You've come too far to drop it all now :clap:

Sorry, should have been clearer. I thought you said you had found a replacement but regassing was the barrier.
Even though the replacement was not as ruggedly built, given its likely use (ie, sporadic, not continuous as would be for say a cold store) would it be 'good enough'
Of course, original refrigerant (r12? ) may be illegal to work with without a licence, but later types seem to be available as diy.
Although not trivial...

Graham, what a nice thought!
Russ, I don’t think sourcing a replacement equivalent unit would be too much of an issue apart from the cost. They seem to be north of £1500 new, and dubious used ones pop up starting at £250 /£750 mark though none are identical.
Before committing anything like that sort of money I some how need to get a bit of confidence that the rest of the furnace equipment is reasonably sound. I do remember that when the furnace driver was delivered I was able to connect it to one of the furnace bodies and get the electronics to ping and determine the resonant frequency. At the time I had no chiller and no high power 3 phase supply in fact I was running off a Transwave static converter off a 13 amp socket! Obviously I couldn’t go any further without a massive power source.
So I think probably my next objective is to repeat that experiment.

This sounds like a good plan!! Looking forward to the results!!
All the best, Matthew.

Ah. OK. I read your previous post as saying that a replacement was gbp 250 - 1500 is a different matter....
