This episode is a replay of a recent Refrigeration Mentor Community Meetup where we helped fellow techs with some technical CO2 refrigeration troubleshooting. The live group discussed a problematic CO2 store with high superheat, recurring low-temp oil issues, phase-loss/current-imbalance alarm and others. You'll hear solutions, tips and advice from the fellow techs on the call, including Mikaela Law, Patrick Gregory, Andrew Freeburg, Billy Carlson, Noah Walker, and others.
