Technical Highlights
“Zero Leakage” Inlet Guide Vanes
•Adjustable inlet guide vanes provide optimum flow patterns as
well as precise and continuous control across the machine’s full
operational spectrum
•Self-energizing back plate maintains zero sidewall clearance for
maximum expander efficiency
•Zero backlash variable guide vane configuration provides smooth
turn-up capability to 125% of design flow
Rugged Rotor Design
•Stiff rotor shaft and high capacity tilt pad bearings assure maximum
stability at all operating loads and speeds
•High capacity tilt pad thrust bearings provide the extra margin
necessary to handle transients
Dual Independent Labyrinth Shaft Seal
•Reliable teeth-on-shaft design is precision machined to ultra
close clearances, minimizing seal gas consumption
•Dual port, atmospheric center vent prevents process stream
contamination
Self-Aligning Wheel Attachment
•Tapered bore and stretch rod design automatically compensates
for thermal and mechanical changes to maintain alignment under
all operating conditions
•Precision machined tapered bore/shaft attachment allows
independent balancing of turbine wheel and shaft to facilitate
field repair
•Numerous bearing designs available to accommodate specific
process applications, including hydrodynamic (journal and tilt pad)
bearings, ball bearings, ceramic bearings, and air/foil bearings
•Sealing design offers robust construction and reliable performance
