Impeller
Highly efficient impeller based accumulated technologies and the latest computer design technology
Precisely processed by 5-axis CNC allows a perfectly designed figure while having excellent surface illumination, strength, durability, and wear resistance compared to other casting products
Semi-permanent longevity is guaranteed by using titanium (T16AL-4V) with excellent durability and anti-corrosion or high-strength stainless alloy steel
Provides highly efficient and wide operation environment with impeller application of backward lean & splitter type
Bearing
A journal bearing that supports high-speed rotor has 5 tilting pads with an automatic caution function. Also, it guarantees the rotor’s stability with the tilting pad bearing’s loading capacity and its dynamic characteristics.
Taper-land and double-acting type thrust bearing absorbs thrust forces in the axial direction efficiently
Compressor body (gear case)
Horizontally split design allows convenient inspection of parts, quick and easy disassembly and repair onsite.
Control panel
CHORUS control panel is user-friendly
10” touch screen is placed and a fully automated operation environment allows automatic control.
