As facility managers prepare for the warmer weather, Goodway Technologies is sharing a reminder not to forget about cooling tower cleaning. A well-maintained cooling tower is always important. Overdue cooling tower maintenance can have a costly impact on efficiency and equipment lifespan, but also pose a serious public health concern.
A dirty cooling tower can result in an overgrowth of infectious bacteria, such as Legionella, and cause an outbreak. According to a survey conducted by Goodway, 88-percent of respondents indicated that Legionella prevention was very important or extremely important from management’s perspective. More than half of survey respondents, comprised of facility managers and personnel in a variety of industries, also acknowledged the potential risk of Legionella from cooling towers comes up in conversation with leadership at least every few months.
Taking the right steps to prevent Legionella isn’t just a personal preference. The introduction of ASHRAE Standard 188-2015 established minimum risk management requirements for building water systems. These specifications provide guidance on logging, maintaining and cleaning cooling towers to mitigate Legionella breakouts.
“Facilities should also have a plan in place, should the possibility of contamination or concerns arise,” said Ray Field, director of liquid solutions at Goodway Technologies. “Our survey shows facilities put a great amount of effort toward implementing cooling tower maintenance programs, frequently conducting visual inspections and making sure a solid water treatment program is in place.”
Cooling tower maintenance should generally occur at least twice a year, preferably before and after the cooling season. The presence of scale, slime or sediment indicates a need to clean the tower. While its importance isn’t new, maintenance is gaining more awareness across engineers and facility management alike. Facility managers and contractors are at the forefront of cost savings for facilities and through proactive maintenance programs, can help deliver considerable cost savings.
What are some proper steps for cooling tower maintenance and cleaning?
Having the right equipment in your lineup
One component of getting the job done effectively and efficiently is having the right equipment. There are clean-in-place solutions that allow you to perform maintenance without shutting the system down. Goodway has a variety of solutions that can help make cleaning cooling towers easier and more effective such as:
