After an eight-week follow-up by us, accompanied by the Head of Maintenance, visual observation on the hot water tank and pictures. We found that the resistance and the walls of the tank were clean. The scale had loosened and fallen off, and it was a friable proof of the effect of the Vulcan treatment.
The condenser and the oil cooling system have problems such as scaling and biological slime. It needs to be cleaned once every 3 months. The normal scale inhibitor dosage is about 200 kg per month. Besides, algaecide needs to be added every year from April to October. The Vulcan descaler save this company 4,733 USD every year!
