Flushing and filtration processes, corrosion and bacteriological conditioning of the closed-circuit heating cooling systems, equipment, and BASF Freezing and Corrosion preventive heat transfer liquid Glythermin NF dosing were carried out in the annex building of the Republic of Turkey Presidency Complex, undertaken by Rönesans Holding. 

Throughout the works, the relevant water quality and control tests were followed by our certified supervisors from an accredited institution of European origin, and the target frost temperatures were tested in the section where the anti-freeze chemical was dosed and handed-over with the desired standard.

Our supervisors, who were educated in the UK and qualified for certification in flushing operations, have reported the whole process with international methodology.
