Abstract

The invention relates to a method and a self-purifying filter unit, which can be build into heat exchangers such as plate heat exchangers. The self-cleaning effect is achieved by the use of tilted scraping elements, which scrape off the filter in a rotating movement. The scraping elements are mounted on a centrally placed shaft, which passes through the whole length of the filter, and it can rotate by activating a connected engine. When the shaft rotates the scraping elements scrape off impurities from the filter, which are then collected in a drain, from where the impurities can be removed from the filter unit. The self-cleaning process can be carried out automatically without the use of manual labour. Heat exchangers with self-cleaning filter units integrated or build onto them in relation to the invention are compact, robust and efficient, with high durability and low maintenance costs.
