The LSTE is a forced draft, centrifugal fan design cooling tower with a capacity range of 33 to 1,300 nominal tons (147 to 5715 kW). Standard construction consists of G-235 (Z725-Europe) galvanised steel with type 304 stainless steel available for the basin or the entire tower.
The LSTE Cooling Tower product line is highly efficient design constructed for long life and minimum maintenance. It is the ideal choice for forced draft replacement applications, low sound and indoor installations.
Warm water from the heat source is pumped to the water distribution system at the top of the tower. The water is distributed over the wet deck fill by means of large orifice nozzles. Simultaneously, air is forced through the air inlet louvers at the base of the tower and travels upward through the wet deck fill opposite the water flow. A small portion of the water is evaporated which removes the heat from the remaining water. The warm moist air is forced to the top of the cooling tower by the fan and discharged to the atmosphere. The cooled water drains to the basin at the bottom of the tower and is returned to the heat source.
The vertical air discharge of the LSTE design and the distance between the discharge air and fresh air intakes, reduces the chance of air recirculation, since the warm humid air is directed up and away from the unit.
