Abstract
A method for protection of compressor modules against undesirable influx of contaminated gas, comprising a pressure housing () which by means of one of more sealing elements () is generally divided into a first compartment () equipped with a compressor () and a second compartment () equipped with a gas-filled motor (), the compressor and the motor being drivably connected to each other by at least one shaft (), is distinguished by protecting the second compartment () with motor () against direct influx of contaminated gas from the first compartment () with compressor () by means of compressed gas that is supplied from a withdrawal point () at the first or intermediate stage of the compressor, or from the compressor outlet (), and by introducing the compressed gas directly into the seal () or in between two or more seals so as to flow through the at least one seal () back to the first compartment (). The invention also relates to an apparatus for use in connection with the method.
