DEJONG has a Research Development Department with its own Laboratory for research and testing in the field of heat transfer, metal fatigue and corrosion. In addition to fundamental research DEJONG also conducts applied research for new designs according to customer specification. The knowledge of functioning and effect of the various parameters that determine the heat transfer in the hot water tank, are essential for an optimal performance of a new design.

Besides an excellent performance also the cost price plays an important role. The use of materials (eg. the wall thickness of the hot water tanks) is therefore being precisely attuned to the specific application. Stress calculations with the help of computer simulations and extensive testing of designs on performance, durability and susceptibility to corrosion are essential in this process. Because of the long field experience and the know how obtained from own research, DEJONG creates optimal constructions and innovative solutions for the various products.
