Question 1

what's the actual difference between Coffee-Tech's gas models?

Accepted Answer

batch capacity and hourly output scale up through the line. the Ghibli R15 runs 3 to 15 kg batches with roughly 60 kg per hour potential, while the Solar 9 handles 1 to 9 kg batches. all their gas machines use fully modulating burners and include profile logging, drum speed control, and cyclone chaff collection as standard. the R15 draws 2500W electrical and weighs 400 kg. construction uses the same closed ceramic combustion chamber design across models. gas consumption stays around 1 to 1.5 kg per roasting hour regardless of size.

Question 2

do Coffee-Tech roasters need afterburners?

Accepted Answer

depends on local code and your exhaust setup. Coffee-Tech machines use negative pressure combustion chambers that pull secondary air through specific ducts, which they claim keeps smoke and odor out of the immediate workspace. but that doesn't eliminate what goes up the stack. they sell standalone afterburner units as accessories, which tells you plenty of customers need them for permitting or neighborhood relations. if you're in a shared building or have strict air quality rules, budget for afterburner costs on top of the roaster.

Question 3

how much floor space do these actually take?

Accepted Answer

the Ghibli R15 measures 114 cm wide by 173 cm deep by 182 cm tall and weighs 400 kg. Coffee-Tech emphasizes compact design, and their footprints are smaller than some competitors at equivalent batch sizes. but you still need clearance for the cyclone, ductwork, service access, and green coffee staging. figure at least 3 meters by 3 meters of dedicated floor space for the R15 plus ventilation routing. their machines mount on casters, but at 400 kg you're not moving them around casually.
