Built to last,
Built to last,
built to clean.
A roaster you keep for twenty years is the most sustainable one you can buy. Kaldera pairs a repairable, cast-iron build with full electrification and low-emission burners — so cleaner roasting is also cleaner air.

01 · Zero on-site emissions
Full electrification
Our electric thermal core matches gas development time with no on-site combustion at all — ideal for city roasteries and grids moving to renewable power.
02 · Clean air
Low-emission afterburners
Where gas is used, an integrated afterburner and cyclone strip smoke and particulate before exhaust — meeting the strictest urban air limits without a separate stack.
03 · Longevity
Repairable by design
Cast components, standard fasteners and open documentation mean a Kaldera is serviced, not scrapped. Twenty-year-old machines still roast on our support.
