Corrosion alarm: Corrosive gases in the air
Hazard detected, danger eliminated - corrosion protection made simple
Corrosion – once the process starts, it quickly becomes too late. In industrial systems, especially in high-tech areas such as data centers, switch cabinets, semiconductors or the like, this can have serious consequences and cause disruptions in production processes. Losses in productivity and profitability are inevitable. Not to mention safety risks and health hazards from reactive particle and gas contamination.
Anyone who wants to avoid the consequences of corrosion and the high costs of repairs or replacements must take precautions to prevent corrosive gases in the production environment. It is easier than you think to detect and eliminate the risk of corrosion by using Carboactiv Corrosion Coupons for determining the harmful gas load and by utilizing molecular air filters made by MANN+HUMMEL.
Corrosion – What is it?
Everyone is familiar with rust, the reddish coating that forms on iron. Rust is caused by the corrosion of iron or steel. However, this insidious decomposition of materials due to chemical or electrochemical reactions with corrosive gases also affects other metals, such as copper and silver.
The metallic corrosion process takes place when these three factors are present at the same time:
- Metals – usually iron or steel, but also especially copper or silver, which are both used in electrical and electronic systems.
- Corrosive particles or gases, such as sulfur dioxide (SO2), hydrogen sulfide (H2S), nitrogen dioxide (NO2), and chlorine (Cl2)
- Moisture
Warm temperatures can also accelerate the corrosion process.
Corrosive gases – determining the degree of exposure to prevent serious consequences
In many industries, too little attention is paid to the formation of rust on equipment parts or the corrosion of sensitive electronic control elements. But if you want to avoid rust and corrosion, you have to take preventive and proactive action. The earlier the danger is detected, the more effective the measures to counteract will be.
Corrosive gases that occur as waste products in many industrial processes (sulfur dioxide (SO2), hydrogen sulfide (H2S), nitrogen dioxide (NO2), and chlorine (Cl2)), can be individually determined in the air when they occur, but this is by no means a useful indicator of whether the environment is corrosive or not. This is because corrosion is an insidious process, and the presence of multiple gases can lead to synergy effects that are difficult to quantify. Even costly monitoring systems are not always able to predict corrosion when measuring individual gases or a mixture of specific gases.
Our Solution: Carboactiv Corrosion Coupons – copper and silver-based coupons
Can be used to identify and measure corrosion sources – cost-effectively, easily, and quickly.
The corrosion coupons are based on copper and silver, meet the requirements of ISA71.04/ASHRAE TC9, and are installed in the environment being tested. They start to discolor through contact with corrosive gases and depending on the temperature and humidity of the ambient air. After a predetermined period of time, the visual difference indicates the potential risk of corrosion. However, only laboratory analysis can provide an accurate indication of the severity and causes.
We conduct laboratory analyses of your Carboactiv Corrosion Coupons in our own laboratories at MANN+HUMMEL.

Prevent corrosion with MANN+HUMMEL molecular air filters!
To prevent corrosive damage to plant parts and electronic control elements, the concentrations of corrosive gases in the environment should remain within severity level G1 Mild.
Suitable filtration systems or other remedial measures can be designed to cope with specific contaminants and sources for severity levels G1, G2, G3, and G4, depending on the corrosiveness of the ambient air.
