BALINIT PROTECREACH compliant coatings for enhanced protection on industrial gas turbine compressors

BALINIT PROTEC for enhanced protection on industrial gas turbine compressors
BALINIT PROTEC for industrial gas turbine blades

Solid Particle Erosion (SPE), Liquid Droplet Erosion (LDE) and corrosion of turbine blades are three key defects that significantly influence the performance of gas turbine compressors. This should not be underestimated as the resulting decrease in efficiency will cause an increase in cost for your plant.

BALINIT® PROTEC by Oerlikon Balzers is a REACH-compliant coating especially developed to protect industrial gas turbine compressors from corrosion and erosion. Moreover, this new PVD coating can substantially improve the efficiency of compressors.

As a leading global supplier of surface solutions with almost 75 years of experience, based on a strong R&D department, we at Oerlikon Balzers understand the needs of our customers. This has always been our motivation to passionately develop the right PVD coating solution in close partnership - perfectly tailored to your needs.
