A method for the cleaning of a bundle of pipes (112) in a heat exchanger fitted in a holder (113) is described, where the pipe bundle is brought into contact with a liquid like cleaning agent to remove the impurities from the pipe surfaces in the pipe bundle. It is characterised in that an upward, open bag-formed casing (1) is brought to surround the pipe bundle and its upper opening rim is fastened in the holder unit (113) of the exchanger-pipe bundle (12) and the bag is supplied with and filled up with cleaning agent which thereby comes into contact with the pipe surfaces, whereupon the cleaning agent with the removed impurities is removed from the bag form (1). The system according to the invention is characterised by - a first unit A comprising an upward, open bag-formed casing (bag) (1) designed to surround the cooling pipes and means for fastening to the cooling box, and also means for connecting pipes/hoses for the supply of the cleaning agent and a removal for the used cleaning agent, said pipes/hoses are connected with another unit B, where the unit B comprises a container for cleaning agent, outflow pipe pieces to connect hoses to the bag (1), and also pump(s) for the delivery of fluid/cleaning liquid, a motor for the operation of the pumps and also a filter unit for cleaning and further handling of used cleaning agent from the bag, and return (recirculation) of cleaned cleaning agent to the bag (1). |
