Corrosion protection for every challenge

Eliminate contaminant gases. Protect electronic components and processes.

Corrosion is a electrochemical oxidation of metals which causes damage by producing oxides and salts on surfaces.
This is caused by specific corrosive gases, which evolve in certain manufacturing and chemical processes.
Corrosion protection is essential as conductivity and its resistance change in the affected electric boards and electronic circuits. This results into malfunctions, failures or damages of equipment. The consequences can be reduced process efficiency, additional maintenance expenses, costly repairs and unplanned downtimes.
Lower your costs by protecting all sensitive areas against contaminant gases and corrosive processes.

Corrosion control thanks to gas phase filtration

Solutions from Freudenberg Filtration Technologies for sustainable process protection

Even though the problem of corrosion is nearly the same, the source varies from industry to industry. High relative humidity (> 50% rh) and high temperatures (>25 ºC / 78 ºF) can increase the corrosivity of contaminant gases. A distinction is made between acidic gases (H2S, SO2, SO3, NOx, Cl2, ClO2, HF), alkaline gases (NH3 )and oxidizing gases (O3). These gases typically affect server rooms, control rooms, motor control centers (MCC), electric substations, air compressors and offices.
