The LPT is a low noise, low height, forced draft, centrifugal fan design cooling tower with a capacity range of 27 to 331 nominal tons (119 to 1455 kW). Standard construction consists of type 304 stainless steel cold water basin and G-235 (Z-725 Europe) galvanised steel casing with all type 304 stainless steel construction available.
The LPT Cooling Tower product line is a combination of EVAPCO’s extensive forced draft cooling tower experience and engineered solutions design philosophy. The result is the quietest, easiest forced-draft tower in the industry to maintain and operate. The LPT’s engineered design features are described below.
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(s) 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 LPT 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.
