Since 1987

Tulderhof was founded in 1987 by broiler farmer Jan de Graaf. In that year, Jan developed his own ventilation system for his barn and put this product on the market under the name Tulderhof Agrosystems. In the following years, Tulderhof developed several innovative ventilation systems for livestock farming, including Tulderhof air inlets.
