ProBlade ™ Ultra Superior leading edge protection Excellent erosion resistance Increased asset value Easy & fast application

ProBlade ™ Ultra is the answer to leading edge erosion WHY PROBLADE ULTRA? Increasing blade lengths, faster tip speeds and harsh weather conditions make leading edge degradation the biggest contributor to blade repair costs and lost revenue from turbine downtime. ProBlade ™ Ultra allows turbine manufacturers and asset owners to safeguard their assets, maintain an optimal Annual Energy Production (AEP) and lower the levelized cost of energy (LCoE). ProBlade ™ Ultra is an innovative leading edge protection (LEP) comprising a resilient elastomeric polymer and a pressure sensitive adhesi

ProBlade™ Ultra LEADING EDGE EROSION: AN AEP AND COST ISSUE Leading edge erosion repairs account for more than half of the blade repairs, constituting a very large portion of repair costs and lost revenue from downtime. ProBlade ™ Ultra is a superior solution offering a long lasting and reliable leading edge protection while limiting vastly its impact on AEP - compared to gelcoat and other existing leading edge protection solutions on the market. Excellent erosion resistance Your leading edge remains intact for longer Increased asset value Increased lifetime, lower maintenance costs and sustained...

ProBlade™ Ultra Better performance by design ROBUST & RELIABLE The molecular structure of ProBlade ™ Ultra is the secret behind its excellent erosion resistance, outstanding low temperature flexibility and exceptional resistance to microbial degradation. It is lined with an ultra strong, pressuresensitive adhesive which bonds to different surfaces and secures that the leading edge remains protected throughout the turbine’s operational life. Pressure-sensitive adhesive Finally, a polyethylene backliner ensures the storage life of ProBlade ™ Ultra, as well as its integrity during the application...

In the lab and field: proven superiority ADVANCED TESTING CAPABILITIES In our Technology Center of Lunderskov, Denmark, the development of ProBlade ™ Ultra has benefited from state-of-the-art testing equipment: Our Wind Tunnel has allowed us to validate the aerodynamic modelling of ProBlade ™ Ultra with asymmetric application & wind speeds up to 105m/s. Our Rain erosion test rig supported to verify the lifetime of ProBlade ™ Ultra under a selection of rainfall intensity, droplet sizes and at varying tip speeds. All of LM Wind Power’s testing procedures are in compliance with the DNVGL-RP-0573...

ProBlade™ Ultra VALIDATED IN THE FIELD After 3 years in operation, ProBlade ™ Ultra has proven to withstand tough weather conditions and remains intact with no sign of failure. Field inspection results have proven Problade ™ Ultra’s resistance to erosion on two of our customer sites placed in the harshest environments, exposed to monsoon climate and rainforest conditions. Blades equipped with Problade ™ Ultra showed no sign of leading edge damage compared to other blades on the same sites using other leading edge protection solutions. Increased lifetime prototype blades Rainforest and nearshore...

1 Product 2 Application environments ProBlade ™ Ultra is available in two different shapes which are optimized for its points of application

ProBlade™ Ultra 1. ON-SITE APPLICATION One meter precut segments tailored for field use make it easy to apply ProBlade ™ Ultra through rope access, cherry pickers or any platforms. The large temperature window at which ProBlade ™ Ultra is installed (+8 oC to +38 oC) ensures limited downtime and faster return to operation. In addition, Installation is free of sealant and specialized tools. Wide application window No need for sealant Faster return to operation, less downtime 2. FACTORY APPLICATION In addition to field application, Problade ™ Ultra is also applied in our factories on new blades....
