Integrally Geared Centrifugal Compressors

Ask Kobelco! The Best Solution for Any Gas Compression.


"SuperTurbo" - Integrally Geared Centrifugal Compressor for process gas services

Kobelco has been developing various process gas services by integrally geared centrifugal compressors “SuperTurbo” per API 617. Based on the accumulated technology of the integrally geared compressor, the SuperTurbo centrifugal compressor was first manufactured in 1982. As the pioneer of integrally geared compressors in Japan, Kobelco continues to expand applications worldwide.

Effective for a Broad Range of Gases

Kobelco SuperTurbo can handle any gas - including inflammable, explosive, corrosive and toxic gases.  Kobelco machines are operating successfully on gases such as chlorine, hydrocarbons, ammonia, carbon monoxide, carbon dioxide, oxygen and their mixtures, including very corrosive gases.  This broad compatibility in gases is made possible by dry gas seals for which any configurations can be offered: tandem, double and single.  Other shaft seals are also available depending on the gas characteristics and other specifications, such as carbon packing seal for chlorine and carbon dioxide gases and labyrinth seal for oxygen gas. 

SuperTurbo compressors have a wide application range in capacity [from several hundreds to 450,000 m3/h (265,000 cfm)], as well as in pressure [up to 100 bar (1,500 psi) discharge pressure] with the capability to include 8 impellers on one machine.

The design also provides the opportunity to combine several compression services on one unit, or even a combination of compressor and expander turbines.  Our references includes a combination of nitrogen recycle plus make-up for air separation plant as well as process gas plus off-gas expander for nitric acid plant and many more.
