Welcome to your Fan Buddy.

The Fan Buddy™ - EMC Calculator is a simple, powerful tool that helps farmers and grain managers determine the Equilibrium Moisture Content (EMC) of the air entering their bin, based on the users temperature and humidity inputs. Whether you're managing corn, wheat, canola, or any other commodity, this app helps you make smarter aeration decisions with confidence. 

Most grain goes into the bin with a “hope it dries okay” strategy. But EMC is the key to understanding whether your fans are actually doing any good—or possibly doing harm.

Knowing your EMC means you can:

Optimize fan run times!
 

Avoid over-drying or re-wetting!
 

Preserve grain quality!
 

Save on energy costs!

Rehydrate soybeans!

No more second-guessing your aeration schedule.

We built this because we needed it, and You have long asked for a fast, easy way to check EMC without pulling up a spreadsheet and pouring over EMC charts on the computer. This is it—lightweight, mobile-first, and laser-focused on solving one problem, fast.

Best of all.... IT'S FREE! We’re giving this away because we genuinely believe that once you experience the benefits of managing your grain based on EMC, you’ll be amazed—
not just by the improved grain quality, but by the energy savings too.

Worth it.... but tough! That said, we know it's not easy to manage aeration manually.
Checking bin conditions, running fans, and bouncing from one bin to the next—multiple times a day—just to stay on top of it. It's a lot. It’s worth doing... but it’s not simple.

There's a better way! That’s where automated, EMC-based bin monitoring changes everything. When the time comes and you're ready to take the next step—automating your aeration equipment and letting smart control systems do the heavy lifting—we’re here to help.

For now, we hope the Fan Buddy™ - EMC Calculator brings you real, immediate value. Use it often. Trust it. And when you’re ready for more... we’ve got your back.
