The cooling towers are often found in industries and manufacturing units, which are basically the heat removal devices. These are used to transfer the process or used water heat to the surrounding atmosphere. Some of the common applications of cooling tower include the cooling of the circulatory water that are used in chemical plants, oil refineries, petrochemical plants, power plants, process plants, natural gas plants, semi conductor plants, food processing units and several other…

A fan is a mechanical device, which produces a stream or flow of air/gas. The fans are used both at residential and commercial spaces serving different purposes. These are often used to move air or gases via ventilating systems. In industries, these are used to force air inside the hot steam boilers and help to reduce the temperature of machines and other equipment's. Fans function similar to the compressors, which is relatively at low pressures. These are basically divided as axial and…

The air foil fans are created and designed for moving the high volumes of clean air at low to medium kind of static temperature. Since 1975, it has been used for its promising performance and low energy consumption. The air foil fan blades are inclined backwards and they are created by using the same aerodynamic principals which are used to make an aircraft. The airfoil fans are among the competent centrifugal fans and put forward multiple utilities. These fan blades are also designed…

Axial flow fans - Impact axial flow fans have an aerodynamic profile with high blade twist angles and large chord widths that give the world’s best efficiencies. Energy efficiency improvements of 20-40% over earlier fans are not uncommon. Blade twist angles up to 44 degrees ensure airflow is uniform hence preventing turbulence. Impact fans are hollow and lightweight which reduces the moment of…
