Mechanism

MAC

In 1986, MCO researched and developed a new concept called "High Efficiency & Compact Design" machine which was named Mitsubishi Advanced Compressor (MAC). Since then, MCO has delivered over 1,000 units worldwide for the petrochemical and oil & gas industries.
Today, these machines are still operating with desired stability and efficiency.

Single-shaft, multi-stage compressor

Horizontal split centrifugal compressor

This figure shows a structural diagram of a horizontal split centrifugal compressor.
Multiple impellers are attached to a single rotating shaft, for a multi-stage structure. The gas enters through the intake nozzle, and is compressed and pressurized by centrifugal force as it passes through the impellers, which are rotating at high speed, before being ejected through the ejection nozzle. With this type of compressor, the outer casing can be split in the horizontal direction, facilitating the maintenance of internal parts. The red parts are the critical shaft and impellers. The photos below show magnified views of the impeller, clearly illustrating the three-dimensional design of the internal blades.

Vertical split centrifugal compressor

This figure shows a structural diagram of a vertical split centrifugal compressor.
With this type of compressor, the outer casing is a single continuous cylinder, for a structure which is capable of withstanding high pressures of approximately 50 – 700 barg, or 1000 barg in trials. The internal impellers can be pulled out in the axial direction for maintenance.
