EVVA was founded in 1919. Since then the name has stood for ‘Erfindungs-Versuchs-Verwertungs- Anstalt’ (Invention, Experimentation and Application Institute). EVVA was therefore a start-up back in 1919 and did what start-ups do today: invent, experiment, test and launch innovative products. And that’s what EVVA continues to do. The result: EVVA today holds over 200 patents and is a world leader in mechanical and electronic access systems.
