I am selling my 2002 Diedrich IR-12 Coffee Roaster. Local Denver pick up only. I am the second owner and the roaster has seen very little use with only specialty coffees at medium to light roasts. Aside from minor stratches and paint chips, this machine is in excellent condition. A couple of the red switches no longer illuminate (light behind the switch), but this is purely cosmetic. I've consistently cleaned and maintained the roaster, and it has never seen a fire. It is currently set up for propane, but it can be converted to natural gas with a Diedrich kit. Included in the sale is over $5,000 in Selkirk PS flue exhuast pipe, which is the manufacturers recommended exhaust. You must arrange for your own transport. This machine weighs approximately 1,000 lbs. Additional details below.
