General Product Information

The combination of cleaning process and coating compressor stages power up your turbine

The Advanced Compressor Coating can help improve the profitability of your power plant as it is designed to recover power output and efficiency caused by aging. The gas turbine power output can increase through a complete cleaning of the compressor blades and vanes and applying the coating to all compressor stages. The coating of the stationary and rotating blades provides a smooth blade surface finish, improves the aerodynamic profile, which can help recover compressor aging.

The Advanced Compressor Coating provides performance advantages and offers attractive financial payback options.

Your benefits


The Advanced Compressor Coating can be a highly cost-effective modernization that helps to increase reliability, availability and performance.


Benefits may include:

  • Up to 1 % gas turbine power output aging recovery
  • Up to 0.3 %-pts. gas turbine efficiency aging recovery
  • Minimization of corrosion and erosion
  • Surface roughness reduction

Further benefits can be obtained with applying a routine online compressor washing procedure such as offered through the Siemens Advanced Compressor Cleaning System.


The Advanced Compressor Coating is applicable for the gas turbine frame types SGT5-4000F (V94.3A), SGT6-4000F (V84.3A) SGT5-2000E (V94.2), SGT6-2000E (V84.2), SGT-1000F (V64.3A), SGT5-3000E (V94.2A) and V64.3.


The Advanced Compressor Coating may be combined with other modernizations such as the Advanced Compressor Cleaning System or the Life Time Extension.

Scope of Supply

The scope of this upgrade includes:

  • Improved duplex aluminium-ceramic Coating


We recommend that the Advanced Compressor Coating be performed at a major inspection. The coating can typically be executed on-site using a mobile coating unit. We offer a full range of field service capabilities to help you manage your maintenance and outage schedules.
