The wet bulb temperature is also the dew point of the ambient air. It is not possible or practical to design a cooling tower that can provide cooling water equal to or lower than prevailing wet bulb temperature of the air. Each tower system must be specifically sized for each geographic area’s prevailing summer wet […]

The Wet bulb temperature (WBT) is a site condition measured by placing a thin film of water on the bulb of a thermometer. A non-wetted thermometer reading provides ‘dry bulb’ temperature (DBT) reading. A comparison of wet and dry bulb readings allows the relative humidity to be determined from a psychometric chart or the air […]

Why Evaporative Cooling The advantages of evaporative cooling stem from several key factors. First, evaporative cooling process use the ambient wet-bulb temperature of the entering air as the heat sink, which is typically 10°F to 30°F lower than the dry bulb, depending on the local climate. The lower the temperature of the heat sink, the...

All cooling towers operate on the principle of removing heat from water by evaporating a small portion of the water that is recirculated through the unit. The heat that is removed is called the latent heat of vaporization. Each one pound of water that is evaporated removes approximately 1,050BTU’s in the form of latent heat. […]

An evaporative cooling tower is a heat exchanger that transfers heat from circulating water to the atmosphere. Warm water from the heat source is pumped to the top of the tower and will than flow down through plastic or wooden shells. As it falls downward across baffles, the water is broken into small droplets. Simultaneously, […]
