Keep your equipment operational with Klaren International’s self-cleaning heat exchanger technology. Vertical shell and tube heat exchangers operate with a clean surface, due to the application of a fluidized bed of solid particles. Conventional heat exchangers have the problem of severe fouling in the tubes. This can happen in just a matter of hours in severe cases. With the solid particles of our innovative self-cleaning heat exchanger technology, solid particles will be continuously cleaning the walls of the heat exchanger tubes with a mild scouring effect. These solid particles have diameters of 1.5 to 5 millimeters and consist of glass, ceramic or metal. A constant heat transfer coefficient is maintained by cleaning the heat exchanger tubes at an early stage of formation. Moreover, these particles reduce pressure drop compared to conventional heat exchangers and enhance the heat transfer at lower liquid velocities. When the rate of removal of deposits by the particles exceeds the rate of precipitation of deposits, zero-fouling is guaranteed.
