Name Description
Compressor
Overhung style centrifugal compressor consisting of a rotor assembly, inlet
housing, volute, casing cover, and bearing stand. Optional inlet guide vanes
allow for process control in the absence of a variable speed drive or inlet
throttling valve. Capable of meeting API-617.
Gear Box
Speed increasing gear box designed to increase the driver input speed up
to the rated compressor speed. The low speed shaft can incorporate the
main oil pump of the lube system, when required. Compressor may also be
supplied without gear box if driver can meet the rated compressor speed
and power. Capable of meeting API-613.
Driver
Primary drive options are electric motors, with or without variable fre-
quency drive, and steam turbines. In select instances internal combustion
(IC) engines have been utilized.
Lube Oil System
There are three main options for the compressor lube system. First, an
integral lube system; in which the lube oil reservoir is housed within the
structure of the baseplate, with the lube oil components (pumps, valves,
coolers, and fi lters) mounted on top of the reservoir with the compres-
sor. Second, a console lube system, with separate reservoir, mounted to
the baseplate frame. Lastly, the lube system can be a separate console
shipped loose for installation near the compressor. Lube systems can be
designed to meet API-614 Chapters 2 or 3.
Baseplate
Boxed construction utilizing structural supports for bracing and rigidity.
Grouting pockets, anchor bolt holes and leveling screws are incorporated
into the design to provide additional stability and rigidity during operation.
Lifting lugs are incorporated into the design for ease in transportation of
the equipment from the factory to the job site. Compressors can addition-
ally be supplied with a drip lip and/or non-skid decking.
Controls
Provide conditional monitoring for the compressor, driver and lube oil system.
Additionally,the local control panel (baseplate or off mounted) houses the
intelligence for positioning inlet guide vanes. The local instrumentation and
panel provide real-time, local data through gauges, switches, or transmitters.
