The tedesca eew group, active in the offshore from 70 years, expands the size of the monopile: diameter 12 m, height 120 m, weight 2.500 tons and protects them from corrosion with the thermal spraying system of aluminum (TSA).
From 2017 Eew Group automated the TSA system with robot, realizing numerous advantages:
- Reduction of the production costs of the 40% Compared to manual spray, recovering the disadvantage compared to Air-Less Spray systems.
- More uniform coatings and greater planarity and dimensional stability.
The aluminum coating is followed by the application of an epoxy sealant.
Thanks to the self -regenerating properties, The coating of Al Create an additional cathodic protection (The sacrificial anodes are not necessary), with a duration over 20 years (avoiding intermediate repairs) and with a lower environmental impact compared to traditional cathodic protection.
Our sprayers to the "Advanced" electric arch, entirely electronic management, they are chosen for this type of work.
