Water treatment / Chemicals

Guldager is able to supply all cooling water systems related chemicals.

By adding chemicals inhibitors, biocides, dispersants etc. to the cooling water, it is possible to avoid or minimize the four main issues in cooling systems, namely corrosion, scale, fouling and bacteria growth. Furthermore, it is sometimes necessary to prevent freezing of the cooling water by adding anti-freeze/glycol.

To ensure such cooling systems are correctly maintained and operate at optimum efficiency it is essential that the correct cooling water conditions are established and then maintained at all times. This can be achieved using carefully selected cooling water treatment chemicals preferably based on a water and plant analysis.
