THE WHIRLER™ is a fully automated online condenser tube cleaning system. It ensures completely clean condenser tubes which results in excellent improvement in plant efficiency and reduction in power consumption.
THE WHIRLER™ is a closed recirculating loop in which sponge cleaning balls are injected into the cooling water inlet line. The balls carried along with water flow and passes through the tubes to clean the inner tube surface. The cleaning balls are then collected at cooling water outlet line. These collected balls are again recovered in the system and the cycle repeats.
Fouling and scale formation increases energy consumption and ultimately cause system shutdown. Effective water treatment can minimize the possibility of high head pressure and excessive energy consumption caused by condenser deposition.
Fouled condenser tubes are common cause of high head pressures. Fouling increases the resistance of heat transfer from the cooling water to refrigerant. In order to maintain the same heat transfer rate, the temperature of the refrigerant must be increased. The compressor fulfils this need by increasing the pressure at which refrigerant is condensed. With a centrifugal chiller 1°F increase in a condensing temperature increases compressor energy consumption by approximately 1.7%.
