The development of the self-cleaning fluidized bed heat exchanger was started by Dr. Ir. Dick G. Klaren for seawater distillation plants by finding a practical solution for the hydraulic stabilization of multi-parallel fluidized beds and recognizing the excellent heat transfer film coefficient in a fluidized bed at very low superficial liquid velocities. Since Dec’2022 KLAREN Technology is one of the competence brands of Taprogge GmbH. The technology can be applied in heaters, coolers, evaporators, crystallizers, reboilers, and condensers.

Taprogge employs an international team of engineers and cooperates with a network of specialists. We design, engineer, manufacture and commission the self-cleaning fluidized bed heat exchangers.

Our self-cleaning configuration can be realized in all manner of industries. A fluidized bed of solid particles is used at the tube side of the self-cleaning heat exchangers where the fouling liquid flows through. The solid particles create a scouring effect on the tube wall surface which removes the developing fouling layer. This prevents severe fouling of shell and tube heat exchangers. Our designs operate up to zero-fouling.
