PolarCool News & Tips

Evaporative cooling systems rely on water to lower air temperature efficiently. However, the quality of water used plays a critical role in determining system performance, maintenance needs, and overall lifespan. Using water with high mineral content, incorrect pH, or biological contaminants can significantly impact the efficiency and durability of your cooling system.

Evaporative coolers, also known as swamp coolers, are highly effective in dry climates, but how well do they work in humid locations? High humidity limits their performance because the air is already saturated with moisture, making further evaporation difficult. Typically, these systems work best when relative humidity is below 40–50%.

Understand how ventilation enhances the natural processes the human body uses to stay cool, including convection, radiation, and perspiration.

Learn how to size an evaporative cooler correctly. Calculate required CFM, adjust for environmental factors, and choose the right cooling fan for your space.
