About us

Founded in Vietnam in 2017, we was known as the youngest branch of Trainor Norway, the world’ class specialist company in the hazardous areas since 1996. Over 3 years, the company has gone from strength to strength and nailed our brand as an expertise company offering the outstanding quality of Ex Training, CoPC Examination and Ex Consultancy with the flexibility of languages, locations and services.

On 1st August 2020, we changed our brand name and corporate identity to TESV – ATEX & IECEx Production, which mirrored the growth to be separated and independent from Trainor Norway and the transformation of the company to produce more Ex products based on ATEX & IECEx standards besides the services which we have successfully offered so far.
