DEJONG is based in Gorredijk and produces more than 120,000 hot water tanks annually, varying from 1 to 1,000 liters. These tanks are developed in consultation with the customer to ensure that the system which the tank is part of, can function optimally. Meanwhile this has resulted in hundreds of different designs that are serial produced for a large number of OEMs and system builders in Europe and North America. In addition, DEJONG developed a standard range for applications where the numbers are (still) insufficient for customer-specific design. The standard range can also serve as a supplement to already existing customer-specific products, whether or not under private label.
