    KOMPBERG BKB22 TWIN boosters. 2. Operating safety rules The present rules are valid for BERG compressors. In addition to the H&S and Technical Supervision regulations applicable to compressors, their assemblies and accessories, the safety instructions given below should be followed in particular. The operators are supposed to observe safe work practices.

  • Page 5: Operating Safety Requirements

        The compressor should be installed in a closed room, in cool and clean ambient air. Never block air flow to and from the room. Ensure sufficient flow of cooling air and extraction of heated air out of the room. The air sucked in should contain no vapours or flammable gases, e.g.

    The cross sectional area of conductors should be matched to the current drawn by the booster compressor. 3 x 50 mm + PE wire is recommended for the KOMPBERG BKB22 TWIN with a motor power output of 45 kW (i.e. 2x22 kW). The KOMPBERG BKB22 TWIN booster should be supplied from a switchgear provided with a time delay fuse (rated for 125 A) and a breaker allowing to completely cut the power supply out.

        6.3. Oil pressure control Oil pressure in the lubrication system with the compressor running should be between 0.2 – 0.4 MPa, and the value should be checked on a pressure gauge connected to the oil pomp connection pipe. The adjustment should be performed when the compressor has heated up and after the state of heat balance has been reached, i.e.
