Visa regularly organises training courses; this is one of our most popular initiatives that is open to technicians and distributors and is free of charge. These training courses are often done in collaboration with the College of Industrial Experts and Engineers and credits are given*.
*ask Service for details
The courses can be organized at Visa’s facilities or at an external location. The speakers are specialists in their field and deal with norms and regulatory aspects, sizing, additions and interaction between the plant and genset(s).
Course participation at Visa’s facilities has the added benefit of being able to do practice sessions with genset simulations in the modern test bays.
If interested, send a request to our Service dept, or check the News section on the website for upcoming course dates.
