Heat Exchanger plays a crucial role in many industries when transferring the heat from one medium to another. Fouling and Scaling of the Heat Exchanger Tubes are the significant aspects that influence the performance of heat exchangers when cooling water is used as a circulating medium. In GEA BGR, we provide an Online Tube Cleaning system for continuous cleaning of the Heat Exchanger tubes with the plant in operation.
Online Cleaning of the Heat Exchanger is carried out by passing slightly oversized Sponge Rubber Balls through the heat exchanger tube. Heat Exchanger tube cleaning system is a closed recirculating loop through which the Schmitz Cleaning Balls are injected into the Heat Exchanger cooling water. The cleaning balls pass through the tubes, clean the inner tube surface, and then collected by a ball strainer positioned downstream of the Heat Exchanger. Cleaning balls are re-injected by a ball recirculating pump skid through the ball injection nozzle installed on the Heat Exchanger cooling water inlet pipes.
GEA BGR observes our clients’ application and process requirements and provides equipment such as Zero Ball Loss Technology for smaller condensers accordingly. Our In-catch technology provides zero ball loss which is proven and running successfully in our Installations.
