Over 50 years of experience

What started in 1951 with the founding of a craft business in Waldenbuch, has developed into a success story with numerous innovative highlights. In 1954 the series production of preheater washing boilers started. Following this "in series production" came heating oil tanks, cylindrical tanks made from glass-fiber-reinforced plastic (GFK), the legendary double-walled NAU-GFK-Ball (one of the safest forms of tank) and containers as well as roller containers. In the 80’s, the NAU GmbH got involved in storage tank technology and produced hot water storage tanks (up to 2,000 liters) in series. A new era began in 1993 with the production of solar collectors and rainwater systems.
