Always up to date, but with a rich history
DNH is founded shortly after the 2nd World War, by three Norwegian sailors. Even then, the company managed to adapt to new developments in the market and worldwide regulations as soon as possible. For example, DNH produced the first explosion-proof loud speaker. This was in 1962. Furthermore, they produced variants resistant to heat, vibration, a constant spray of salt water and fumes of chemicals.
