<p>The gas for the treatment, such as nitrogen, oxygen, rare gases, a mixture of hydrocarbons or similar, is stored in a tank (1, 2). By means of a pipe-line (81, 82) provided with a flow controller (76, 77) each gas is fed into a mixing chamber (4), the outlet of which is connected to at least one storage tank (3) for the conditioned atmosphere as well as with each treatment booth (10, 11, 12) via an automatically adjusted reheating device (7, 8, 9). For local treatment the liquified gas is tempered by regulating the admission of coolant into the heat exchanger, so that the gas flow reaches the surface of the body to be treated in a homogeneous gas phase. For treatment of the entire body, a conditioned atmosphere of liquid oxygen and liquid nitrogen, mixed in a proportion corresponding approximately to the composition of normal air, is fed to the treatment booth (10, 11, 12) after regulation of the flow.</p> |
