Unit cooling water
Thread Content
The cooling water used for the chiller unit has a conductivity of 1500 us/cm and a pH level of 8.9. Does this have an impact on the unit? For standard units, the required pH level for the cooling water is 6.5 to 8, with a conductivity of less than 100. Will this increase the likelihood of scaling and corrosion? If chemical treatment is used, will the residue of the chemicals harm the unit’s condenser?
Reply to 1# gongweihua: The conductivity is high, which increases the likelihood of scaling; it is best to address this by adding chemicals and carrying out waste discharge
A high conductivity indicates a high degree of ionization in the water, which first exacerbates electrochemical corrosion and then leads to an increase in precipitates and deposits. If the tubes inside the condenser are copper, corrosion has a greater impact. However, the alkaline pH is a favorable factor; it is possible to refrain from adding chemicals for now and to monitor any changes on the metal surface, taking appropriate action only if significant changes occur.
