Why Centrifugal Compressor?

Centrifugal compressors, sometimes termed radial compressors, are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. The idealized compressive dynamic turbo-machine achieves a pressure rise by adding kinetic energy/velocity to a continuous flow of fluid through the rotor or impeller. This kinetic energy is then converted to an increase in potential energy/static pressure by slowing the flow through a diffuser. The pressure rise in impeller is in most cases almost equal to the rise in the diffuser section.

Because centrifugal compressors compress air in stages, the air being compressed stays cooler and the air compressor is more efficient, both mechanically and in terms of the energy being used. Although centrifugal compressors often have a high initial cost, this is usually compensated for by their long and relatively low-maintenance life.

• Highest efficiency comparing to other types of compressors
• Oil-free outlet air without any auxiliary equipment
• Lowest maintenance
• High quality outlet (without oscillations in discharge pressure)
• Capable of running continuously for long periods of time

Engineered Air-Cooled Compressor
Samsung Techwin, as a leader in energy equipment industry, can develop specialized products for certain applications. For severe climates, where supplying water to cool down the compressed air is not conceivable, water-cooled compressors cannot be utilized. Samsung Techwin alongside Siemens, Ingersoll Rand and … are the only air-cooled centrifugal compressor manufacturer all around the world. Havayar Industrial group as exclusive agent of Samsung Techwin in Middle East, with remarkable experiences in such conditions and oil & gas industries, is ready to meet clients’ requirements and supply engineered air-cooled compressors for almost any working condition.
