Hey friends- We're looking to sell our 1999 Diedrich IR-12. We've roasted on this machine for the last 3 years and its been a solid machine. We've never had an issue. Its currently converted to propane but we have the original natural gas adapters still. Its a simple conversion. I believe we're the third owner of the machine. The first owner started to get artsy with one side of the machine and never completed painting it. It doesn't effect the performance and it adds a little character. Its currently set up and running Cropster- which has been an awesome set up for us. The roaster came with a thermal afterburner that we never hooked up but is available. Would love to sell together but willing to separate if interested. 18k. Open to offers. Located in Georgia. Thanks!
