Cooling towers that have not been cleaned can result in algae growth and flash evaporation that produces hard scale deposits or calcium fouling. If your chiller system has a cooling tower, keep in mind that the cooling tower can have a big impact on efficiency and present potential health risks, too. Does your chiller system have a cooling tower? Regularly provide updates on the positive results and impact of the routine maintenance to show the benefits. Share the information with everyone who is involved in facility management or comes in contact with the system. The program will only work if all the necessary parties are informed of the process and have received training on the system. Since every facility is different and may experience different types of scale, it is recommended to reach out to an expert for assistance in identifying the best approach and solution.Īfter developing a chiller maintenance program and outlining all the steps and action items, there is one final step to implementing a successful upkeep plan. It helps to reduce the buildup of contaminants on heat-transfer surfaces and slow the growth of harmful bacteria. Step 4: Sustain proper water treatment - A water treatment program can help maintain efficiencies between cleanings.Refrigerant levels can be tracked by using an air-purge time, checking the refrigerant sight-glass for bubbles, and using a gas analyzer to assess all the joints and connections. Keep refrigerant levels within the manufacturers’ recommendations. It also means that hazardous refrigerants are released into the air. Step 3: Ensure a leak-free unit - In addition to scale, leaks can also be detrimental to the efficiency and operation of the system.Goodway has a selection of chemical descaling solutions, mechanical tube cleaning solutions, and expert consulting services to find the proper cleaning approach. Pressure loss can also indicate tube corrosion. It is recommended to clean chiller tubes at least once a year, but regular monitoring can help identify when cleaning should take place. Even the smallest amount of scale can add thousands of dollars in additional energy expenses.
