Watco Group developed an innovative solution that will improve chiller performance, maximise chiller efficiency as well as reduce fouling related costs by eliminating fouling and scaling and translating it into significant energy savings. One of the biggest energy consumer in most facilities are chillers which can usually consume more than 50% of the electricity. An efficient water management program is of utmost importance to control energy consumption, since the energy required for the chiller to operate accounts for a substantial amount of the facilities’ total energy requirements. Energy consumption depends on the efficiency of the chillers as well as the hours of operation, electricity cost, average load and the amount of fouling. Nevertheless, elimination of fouling and scaling is impossible, even when using the very best of water management programs. If the chiller are not efficiently running it will result in the following; Reliability of the equipment will decrease. Increase in maintenance intervals. Shortened lifespan of the equipment. A decrease in a chiller’s performance, even just a bit, can have a massive impact on its efficiency. For example, each increase of 1 degree Fahrenheit in the temperature of condenser water above full load design can decrease the chiller’s efficiency by 1 to 2 percent. A reduce efficiency of about 10 to 35 percent or even more will be the result of a neglected or failed water treatment program.Also, properly maintained condenser tubes will last significantly longer. When condenser tubes suffers from fouling, acid is used to remove the scales as well as abrasive cutters and steel brushes, which can shorten the life of the condenser tubes. It is quite expensive to replace these tubes prematurely. Investing in preventive maintenance such as the Eqobrush Automatic Tube Cleaning-Brushing System for Heat Exchangers and Chiller Condensers can prevent any extra these fouling related costs. What is Eqobrush? Eqobrush was created and developed to address the formation of deposits and other contamination at the microscopic level that occur during the regular process of operation. Fouling and scaling formation is avoided by high-frequency automatic tube brushing of heat exchanger cleaning or condenser tubes. Brushers nestled at each tube end regularly travel up and down the tubes, powered by the reverser water flow through the flow reversing valve. The contaminants at microscopic level will leave the system through a blow-down or a basin sump in the cooling tower. The system is intended to be integrated in the original plant installation or as a retrospective fit.Thus the necessity for plant shutdown, chemical cleaning, and physical cleaning is radically minimised. Aside from significant savings on energy consumption, the Eqobrush automatic tube cleaning system also provides substantial savings on other associated costs like process interruption or shut downs, chemical or physical cleaning and reduced water consumption as well. Benefits of Eqobrush The prevention of build-up of fouling in the heat exchanger has quite some advantages, such as: Reduce overall fouling related cost. Reduce electric energy consumption in chiller condensers. Reduce fossil energy consumption in industrial Heat Exchangers due to...Continue Reading
