Silon means ‘JET’ in Hebrew.

Silon ZR7 is a work of art dedicated our work to you the coffee artisan.

Silon ZR7 was originally researched and designed as a tool for baristas who craft their own beans, batch by batch, to be served with great professional pride. We envisioned Silon ZR7 for those who deserve the best tool out there. We present you with a roasting machine built to the highest standard in every possible respect. Quality of design all around, quality of build, quality of coffee produced. We crafted Silon ZR7 to be the crown jewel of your coffee-roasting practice, right at the center of your atelier.
