Diedrich IR-2.5 Roasters for Sale

Used Diedrich IR-2.5 Small-Batch Roasters

The Diedrich IR-2.5 is a 2.5 kilo (5.5 lb) infrared roaster built for precise small-batch work, and this collection lists the used units we currently have inspected and ready to ship. It sits between the 1 kg IR-1 and the 5 kg IR-5 in the Diedrich lineup, giving you more output than an entry-level sample roaster without requiring you to step up to a full commercial machine. Every listing below includes condition notes, roast hours where available, and the accessories included so you can compare units at a glance. For the full model range, including the IR-1, IR-5, and IR-12, see the complete Diedrich roaster collection.

Why Roasters Choose the IR-2.5

The IR-2.5 uses Diedrich's infrared burner system, the same technology found across the brand's lineup. Infrared heat transfers energy through radiation rather than direct flame, which supports even bean development and a cleaner cup. At up to 22 lbs per hour, it fits cafes running their own roasting program, training labs, and small-batch roasters who have outgrown a sample unit but do not yet need commercial volume.

Each IR-2.5 in this collection has been inspected before listing, and the details on hours, accessories, and condition are noted on the individual product page. If you are still deciding on the right batch size, our small batch roasters (1-4 kg) collection covers the wider range of options in this class.
