Axial Inlet
Centrifugal Compressor
Dresser-Rand experience in
pipeline centrifugal compressors
is unmatched, having built more
than 800 pipeline compressors
during the last 70 years. Over
the past several years, D-R has
enhanced its technology in a
variety of areas to strengthen its
capabilities in the design and
manufacture of its compressor
product lines – including pipeline compressors.
The D-R Pipeline Direct Inlet (PDI) centrifugal compressor is a single-stage,
axial inlet compressor commonly used in natural gas pipeline service. These
compressors use a direct inlet, overhung impeller and demonstrate flangeto-flange efficiencies to 90%. The PDI accommodates many drive configurations in standard package designs.
