ABSTRACT A method for eliminating detrimental deposits of con- densable gases in the heat-exchangers of a continuously operating low-temperature installation, without totally shutting down the installation, involves introducing hot gas briefly into the cold end of the heat-exchanger. The hot gas is at a temperature of between 0°C and +110°C and contains no condensable constituents. The hot gas may flow almost without pressure through the heat exchanger, or may be introduced into the heat-exchanger until a predetermined pressure is reached and the pressurized gas is suddenly released. In one arrangement, hot gas is mixed with the cold gas during the cold period in a change - over heat-exchanger.
