Flushing and pickling operations were carried out by our company at Altınoran project, which is Turkey's largest life themed project and built by Sinpas Construction Industry Inc. in Ankara Çankaya. Flushing mechanical installation preparation processes and washing processes controlled with chemical analysis were carried out in heating systems and floor stations in the residences of the project consisting of 50 blocks. With this process, which is carried out on-line without disturbing the comfort of the residents, the impurities seen in the installations and the color, sediment and high ions in the water are removed, and it is aimed to improve the efficiency of the heating system.
