In the Kale project, which is undertaken by REC International Investment-Rönesans Holding, flushing (chemical washing) was carried out on all heating and cooling lines by Deser. During the flushing process, the relevant chemical analyses were carried out and the washing process was monitored by our supervisors. The accredited results and the chemical values of the system water are reported, the welding chips, iron dust, and other pollutants are removed from the lines and than handed-over.
