  1. Would it be worth trying to reuse the existing control equipment that is currently attached to the kins? They both have Chromalox 2104, as well as Fire Right Jr. Also just to answer the Size question these 2 kilns are exactly the same size. Not sure why 1 is 10kw and 1 is 18kw. But I would plan to convert both to 10kw.
  2. Ok, yeah that makes sense about replacing the elements/wiring. Attached is a picture of the wiring of the 1997 kiln. There are a few components that I am not sure are depicted on the wiring diagrams sent from Alpine so I was having trouble piecing things together. Also when I talked to Joe from Alpine he stated: So I am not sure if I am just "Lucky" to get a 18kw, or what is going on there...
  3. I have been looking around on the web for answers to this question and this seems to be the best place to try and see if anyone has experience with this. I got a great deal on a couple of Alpine EF-4 kilns recently ($200 for 2) and at the time knew that one was 208v 3 phase but thought one had been converted to 240v. Both kilns seem to be in great shape and so I figured that I could figure out how to convert the other 240v 1 phase... Both kilns were 208 3 phase... I have e-mailed back and forth with Joe from Alpine multiple times and have been able to get the wiring schematics for both the 208v 3 phase kilns as well as the 220v 1 phase and am asking for the 240v diagrams now. And Joe has confirmed that the conversion from 208 to 240 can be done. I was just wondering if anyone had worked with these EF-4 kilns before and if anyone had any advise on the conversion. I have attached a few pictures of the kilns and the wiring diagrams I have received for reference. Any idea's on where to start the conversion or sourcing of parts would be appreciated too. 220v1ph.PDF 208v3ph.PDF
