Your Place, or Ours!

VAI provides a wide range of technical vibration training courses at our Training Center located in scenic New Harmony, Utah right across Interstate I-15 from Zion National Park.

These courses are packed with technic al information, and include everything from Data Collector Training, up to and including ISO Category III Certification Training.

The courses we provide are listed below, and each course requires a minimum of five (5) confirmed students:

  • Vibration Data Collector
  • Vibration Database Software
  • ISO Category I Vibration Certification
  • ISO Category II Vibration Certification
  • ISO Category III Vibration Certification
  • Single Plane Balancing

Students should fly into St. George or Cedar City, Utah.  For those students who want a better selection of flight schedules (and a scenic 3-hour drive one-way to our location) should consider flying to Las Vegas.  While in the area, students should select lodging in either Cedar City or Saint George, Utah.  Both cities have many fine restaurants and motels to choose.

Each ISO Course is presented over the course of five (5) days. They are very fast paced and packed with technical information. As a result, we do NOT recommend students skip any of these courses. Students also have the option to take the ISO exam on the Saturday immediately after the training, but we recommend the following Monday due to the amount of material covered in these courses. In addition to the very intense training and number of topics covered, VAI’s Training Manuals should serve as an excellent reference manual for many years to come.
