It's Cooling Wednesday, and today we're spotlighting the essential systems that keep industrial processes and HVAC systems running smoothly—cooling towers, chillers, heat exchangers—and the dedicated professionals who keep them in top shape.

We all know how crucial cooling towers are for removing heat from a building's process, but did you know there's more to the story? Cooling towers circulate water from a heat source, cooling it down by dropping it through the tower before returning it to the system. But what about fluid coolers and evaporative condensers? Fluid coolers use a tube bundle to keep inside, and outside water separate, while evaporative condensers use refrigerants like ammonia to tackle the heat.

Today's special guest, Loraine Huchler, President of Martech Systems, joins us to share a crucial reminder: "Monitoring and managing biofilm will automatically decrease your risk of Legionella and Legionellosis infections—not just in cooling water, but even in building water." Learn how to keep your cooling systems safe from Legionella by visiting our free Legionella Resources page, where you can find past episodes, articles, and the latest legislation updates.

Whether you're treating a cooling tower, chiller, or heat exchanger, snap a photo of your system today and post it using the tags #IWW24 and #IndustrialWaterWeek. Let's celebrate Cooling Wednesday together and keep the conversation flowing!
