"The Future of Industrial Training: the New Digital Classroom"



About the Webinar:
At TPC Training Systems, we’ve been on the hunt for ways that our industrial skills training solutions can evolve to meet the needs of all of our customers, and we’ve learned some things in the process. In this webinar, we’ll share what we’ve learned and give you a preview of the future of industrial training.

You’ll learn about:
  • The best uses of webcast and simulcast training formats
  • The advantages of blended online and live training
  • Virtual reality (VR) training environments, including an exclusive sneak peek inside a VR simulation

    Air-Handling Systems

    Air-Handling Systems

    This maintenance course begins with coverage of airflow basics, including how air moves, types of airflow, and pressure relationships. Online lessons compare and contrast the various types of fans and fan motors. They go on to examine the types of ducts, fittings, connections, insulation, and terminal devices. Covers various methods of cleaning and filtering air, as well as balancing and troubleshooting the air-handling system. This course concludes with a lesson on indoor air quality and sick building syndrome. Air-Handling Systems is available in online and course manual formats.

    TPC Training Systems is authorized by IACET to offer 0.6 CEUs for this program.
