Corrosion and Rust, Meet Your Match

High humidity levels in the environment have a direct impact on the infrastructures and electrical workings of bridges, water treatment facilities, substations, switchgear rooms and wastewater treatment plants. 

Oxidation of metal structures is known to speed up when RH (relative humidity) in the environments exceeds 50%. Electronic devices, circuit boards, components and data used in the mechanical rooms are also highly sensitive to humidity levels.
