Boiler systems encounter two gases, oxygen and carbon dioxide, dissolved in the water entering them during their working process. The presence of these gases causes corrosion in boilers and heating systems and will disable the device in the long term. Usually, dissolved oxygen in water is removed in two ways, physically and chemically.

Oxygen scavengers, oxygen scavengers, oxygen absorbers, anti-oxygen or (oxygen scavenger) are used to remove oxygen in various industries. The oxygen scavenger reacts with dissolved oxygen and prevents the reduction of oxygen to hydroxide ions, thus acting as a corrosion inhibitor.
