per kilo.
Kaldera roasters recover the heat most machines throw away. Insulated chambers, heat-exchange preheating and demand-matched burners cut energy use by up to a third — batch after batch.

01 · Thermal recovery
Recovered-heat preheating
Exhaust heat preheats incoming air through a compact exchanger, so the burner spends less fuel getting to temperature and far less holding it between batches.
02 · Combustion
Demand-matched burners
Modulating burners follow the control loop instead of running flat-out, matching heat to the bean mass in the drum. You pay for the energy the roast needs — not a degree more.
03 · Mechanical design
Insulated, balanced drums
Double-skin insulation keeps heat in the beans and off the roastery floor, while a hand-balanced drum turns with less drive load and less wasted motion.
