Black Stripe roasts a lot of coffee (Dashboard -> Users -> Search ). Makes the installation very credible.
A couple things to keep in mind-
- Current Aillio guidance recommends an air gap between the roaster and the fan-driven vent line so that the exhaust fan isn’t defeated (especially at low settings) by an in-line fan.
- It never shows up in installation photos, but there has to be a source of make-up air when venting to the outside of a closed space in order to not create a low pressure area around the roaster. In a really well-sealed building the roaster will be throttled for air which will affect exhaust fan flow rate.
- I see they gathered the cooling tray exhaust too. If you do that (seems like a good idea!) you probably need to provide a fan to move a little air under the roaster since the cooling tray provides that function- even when not cooling, that fan is running at maybe C2.
Edit- when I commented on cooling tray exhaust in Apr 2020 I didn’t know the cooling tray fan was kept spinning at low speed to provide air movement under the roaster.
