CO2 Basics: Transcritical Booster Systems

Hi, I'm Rusty Walker.

I'm your instructor for CO2 Basics: Transcritical Booster Systems.

This course will prepare you for practical experience on how sustainable CO2 refrigeration systems operate in the field. I’ll use real tools and workflows to help you build a clear understanding of these systems.

Before we dive in, here's a quick overview of how the course works.

Step 1

The course is made up of eight modules, each featuring short, focused videos. Watch the lessons in sequence at your own pace. Once completed, videos can be revisited anytime. Your progress saves automatically, so you can pause and return whenever it’s convenient.

Step 2

At the end of every module, complete a knowledge check. Earn a score of 80% or higher to continue to the next module. If you don't pass on the first try, that's okay. Try again!

Step 3

Once you pass the course, download your certificate of completion: proof of your new CO2 refrigeration expertise!
