During aeration in the cooling tower, cooling water picks up airborne particles such as dust, soot and microbes. The high temperature of the heat transfer process transforms these airborne particles and soluble salts into scales, which clog up the condenser inner tubes, raising energy cost and degrading the performance of the entire system. Manual cleaning involves high labour cost and the hassle of chiller shutdown.

can be very costly since it directly results in increased electricity
consumption, interrupted operation, and increased maintenance costs.”
