Drying bridges with a DST dehumidifier provides several advantages, as well as an excellent corrosion protection.
Corrosion on bridge constructions can lead to large extra costs if not sufficiently and correctly protected. Directed streams of dry air, below 50% RH, protects the steel constructions from corrosion.
The beams can be protected from corrosion by preventing leakage of dry air through the truss. Corrosive protection with paint is expensive and requires a lot of maintenance.
Painting the bridge increases the weight of the bridge.
A bridge, which corrosion sensitive parts are protected with dry air, requires minimal maintenance and saves a lot of time compared to using anticorrosive paint and coating. Some spots of the bridge are difficult to protect with anticorrosive paint and coating. A dry air solution is therefore perfect.
