Abstract (en)
[origin: EP1482179A1] The compression unit has a radial compressor (35) and electric drive motor (31) installed in a pressure casing (1) with a gas inlet (2) and gas outlet (3), and an encapsulated device (4) with an internal chamber (6). The internal chamber is connected to a pressure reducing device (37) which is constructed in such a way that the latter can effect a reduction in pressure in the chamber. The pressure reducing device consists at least of a connecting pipe (8) to the space outside the pressure casing. An independent claim is included for a method for the operating of a compression unit whereby pressure inside the internal chamber of an encapsulated device is influenced in such a way that it is kept less than or the same as the process pressure inside the pressure casing in all operating states.
