The following sessions will be held Oct. 15-18:

  • “EC Motors-The Fan Drive of the Future,” presented by Moriz Kramer, will review how EC motors work, what an external rotor EC motor is, the power range of EC motors, how to save energy with the right fan drive and more.
  • “Key Observations and Measurements for System Performance,” presented by Jamie Kitchen, will investigate the key observations and measurements as well as the key factors that determine system performance. 
  • “Refrigerants and Regulatory Update-What’s Next,” presented by Ron Vogl, will focus on the current state of refrigerants and use in both refrigeration and air conditioning.
  • “Motor Troubleshooting-Beyond the Basics,” presented by Dennis Bush, will cover a number of troubleshooting situations in detail to determine the next cause(s) of the problem and how it relates to basic principles.
  • “Micro-Controls Link to Net Zero,” presented by Timothy Muckey, CM, will cover the application of micro-controls to reduce global footprint and meet net-zero energy goals.
  • “Psychrometrics 201,” presented by Harlan “Skip” Krepcik, CMS, RCT, will cover using data from the solution schematic to determine airflow volume and refrigeration tonnage.
  • “The TEV Story (The Nitty Gritty on Thermostatic Expansion Valves),” presented by Jon Grable, will take a closer look at the often misunderstood TEV and consider how it plays a role in refrigeration and air conditioning systems.
  • “Disaster is Coming-Are You Ready?” presented by Michael J. Thompson, CMS, will discuss what you do before disaster hits. Attendees will review an incoming “storm” and prepare a plan to ride it out.
