A new service introduced by Alisea consists in restoring the ATU (Air Treatment Unit): restoration work which is aimed at removing the oxidation present on internal surfaces, above all found in the humidification sections and in the collection tanks where water concentration is higher. This stage is very important to control of the hygiene of the air introduced into the environments since iron in an ionic state, generated by oxidation, feeds many microorganisms which can be harmful to health and so encourages the proliferation of bacteria inside the Air Treatment Unit.
When the conditions of these components of aeraulic systems are very precarious it would not be enough to carry out traditional maintenance work, but it is necessary to use more specific methods. The ATU restoration service offered by Alisea is unique in Italy and regenerates the conditions of treated units by restoring them to their initial state.
