If necessary, they co-operate with the large international engineering companies to incorporate the self-cleaning heat exchange technology in all kinds of processing equipment, including complex heat recovery systems, chemical reactors, evaporators, reboilers and crystallizers.Klaren is not interested in the fabrication of the heat exchange installations and prefers to outsource the fabrication to competent manufacturing companies, which should also be acceptable to the actual end user of the equipment.
