I read somewhere that higher elevations have faster roast time and require somewhat lower temperatures. air is thin and has less Oxygen

Yes, 1st off, you must use only Panama Esmeralda Geisha beans and be sure to only roast on Saturdays. Actually, this isn't completely true. Please post in all about roasters forum. Thx!

I’m at 9,000 feet elevation, is there any special adjustments that need to be made to roast using an SR 540 at this elevation?

Simple, bigger, better, faster, SC/TO high torque motor replacement for ~$35

I use two switches to control the heat. On/Off on the SC and full or half heat on the turbo.

I normally have to do very little switching. Seems that my 3 cups of beans, TO, SC, stirring all keep my profile on target. More often I have to slow down the development time with turbo going half heat beginning at first crack for about a minute. Different beans, ambient, wind have slightly different results.

The profile I have online is the one I use with ONE EXCEPTION: I start my timing when the roast hits 200F. ROR is the same after that. The reason is that nothing is happening to the roast before that and the charge temp or time to 200F is less of a concern. You just have to adjust the time scale on the left of the profile chart.

My research with other roasters that have used halogen turbos actually prefer the heating coil. I have no experience myself with halogen.

Conversely, no experience with heating coil, no such models here.

A peculiarity of my setups is the complete removal of halogen cover, this way the IR heating becomes majoritar versus convection, which is good, for my taste... maybe because I prefer meat cooked using a radiant (shawarma) versus convection (oven) Grin

Also tried cheap chinese carbon fiber tubes from Aliex, but abandoned, low reliability in this environment with vibrations, the fiber breaks quickly, after some roasts.

I have used both element and halogen
Both work great and I like both equally

The halogen has one small advantage, that it lights up the roast chamber to view what’s going on inside

I home roast and I like it
