Evaporative coolers are an energy-efficient and environmentally friendly solution for keeping residential and industrial spaces comfortable in hot, dry climates. However, excessive evaporative cooler noise levels can be disruptive and may indicate underlying issues within the system. Understanding what causes these noises, how to troubleshoot them, and how to maintain quiet operation is essential for ensuring both performance and comfort. Common Causes of Evaporative Cooler Noise Evaporative coolers, also known as swamp coolers, operate using a straightforward process: warm outside air is drawn through moistened cooling pads, where water evaporates and lowers the air temperature before it is circulated indoors....

Evaporative cooling systems can deliver exceptional comfort at a fraction of the energy draw of mechanical refrigeration, if they’re maintained with discipline. The following evaporative cooling maintenance tips present a practical, technically grounded checklist to maximize uptime, extend component life, and keep performance high through the most demanding parts of the cooling season. We’ll break the program into what you should do seasonally, daily, and annually, and then dive deeper into the three highest-impact subsystems: pads, water distribution/pump, and water quality/conductivity control. Seasonal Evaporative Cooling Maintenance Tips A seasonal maintenance window, typically late spring before startup and late fall before... View Article

Evaporative coolers are deceptively simple machines: a fan, a pump, a wetted medium, and a sump working together to drive sensible heat from air into liquid water that then evaporates. But behind that simplicity lies a complex chemistry set. The composition of the water circulating through the pads—the evaporative cooling water quality—governs not only immediate cooling performance (approach to wet-bulb, saturation efficiency, airflow) but also the longevity of media and metallic components, the frequency of service, and the total cost of ownership. Key Parameters of Evaporative Cooling Water Quality Water in an evaporative cooler does not behave like water in... View Article

In the realm of climate control and HVAC technology, direct evaporative cooling systems represent one of the most energy-efficient and cost-effective methods for temperature reduction, especially in arid and semi-arid climates. These systems harness the natural cooling effect that occurs when water evaporates into the air, reducing air temperature without the need for energy-intensive refrigeration cycles. Understanding the Principle: How Direct Evaporative Cooling Works At the heart of direct evaporative cooling lies a fundamental physical process: the absorption of heat during water evaporation. When unsaturated warm air passes over or through a wetted medium, it picks up water vapor. This... View Article
