Specification of Chilled Water Treatment
CHILLED WATER TREATMENT (CHWT) COOLING TOWER CHEMICALS
Chilled water system is part of a closed circuit water system as in the evaporator
Cooling Water system. In this part of the evaporator the system is closed, the problems are
often occurs is the problem of corrosion, this corrosion can occur due to the presence of oxygen
dissolved (the colder the water the higher the dissolved oxygen) and also the presence of carbon
dioxide. However, the problem of scale will also occur if the water used is
water containing hardness (Calcium and Magnesium the main forming of crust in water)
height (hard water).
CHWT MATCHEM contains:
1. pH Buffer, serves to control the pH in chilled water
2. Organic dispersant, to disperse sediment that occurs so as to prevent its occurrence
scale formation.
3. Nitrite base anodic inhibitors to prevent corrosion.
