On 17th May 1754, a sales contract for the building of a new blast furnace was signed between Johan Baptist van den Bergh and some local entrepreneurs in Ulft , the Netherlands. This project heralded the start of a company that is still going strong to this day. The company is called De Koninklijke Diepenbrock en Reigers of Ulft or, in short, DRU.
DRU started out as a blast furnace, producing numerous products from cast iron. DRU pots and pans are still well known today. When natural gas was discovered in the Netherlands at the beginning of the 1960s, DRU switched to producing gas fires and wall heaters. DRU is now one of the oldest industrial companies in the Netherlands.
DRU is a modern company that continues to specialise in producing gas heating appliances. It is the largest producer of balanced flue gas fires and wall heaters in Europe and also produces wood and multi-fuel stoves and fires.
In 1999 it relocated from its original home in Ulft to Duiven. The buildings in Ulft, which form part of our industrial heritage, have now been largely renovated and accommodate the “DRU factory” where culture and business come together.
DRU has operations in 3 countries and a dealership network that spans Europe and beyond. On its 250th anniversary, DRU was awarded the prestigious designation of ‘Hofleverancier’ or a Supplier to the Royal Dutch Court.
